Ecommerce marketing statistics for 2026 show budgets flatlining at 7.7% to 7.8% of company revenue, even as acquisition costs keep climbing and channel performance keeps shifting.

Email still returns more per dollar than any other channel, at $36 to $45 for every $1 spent, while organic search remains the single largest source of both traffic and orders.

This roundup pulls together the current numbers across budgets, SEO, paid search, social, email, SMS, influencer and affiliate marketing, conversion optimization and customer acquisition cost, so marketers can benchmark their own program against 2025 and 2026 data rather than guesswork.

Quick answer: Ecommerce marketing budgets sit between 7.7% and 9.4% of company revenue depending on the survey, organic search drives roughly 24% to 44% of ecommerce revenue by channel, and email marketing delivers the highest return of any channel at $36 to $45 per $1 spent (Gartner, 2025; Omnisend, 2026).

Key stats at a glance

• Marketing budgets held at 7.7% of company revenue for a second straight year in 2025 (Gartner, 2025)
• Organic search generates 44.6% of ecommerce revenue, more than any other single channel (Omnisend, 2026)
• Email marketing returns $36 to $45 for every $1 spent, the highest ROI of any channel measured (Litmus/DMA, 2025 to 2026)
• Ecommerce customer acquisition cost has risen 40% since 2023, now averaging $68 to $84 (Mobiloud/First Page Sage, 2025 to 2026)
• Automated emails drive 37% of email revenue from just 2% of send volume (Omnisend, 2026)

Ecommerce Marketing Statistics: Budgets and Ad Spend

Marketing budgets stopped shrinking in 2025, but they have not grown either, and CMOs are redirecting what they have toward paid media and productivity tools rather than headcount.

1. Average marketing budgets held at 7.7% of company revenue in 2025, matching 2024, according to Gartner's CMO Spend Survey of 402 marketing leaders (Gartner, 2025).
2. Gartner's 2026 CMO Spend Survey put the figure at 7.8% of company revenue, up marginally from 7.7% the year before (Gartner, 2026).
3. The CMO Survey, run by Deloitte, Duke and the American Marketing Association, reported marketing spending at 9.0% of revenue in its Spring 2026 edition, with total marketing spend growing just 1.7% year over year, the smallest increase since 2021 (The CMO Survey, 2026).
4. Half of CMOs in the Gartner survey reported budgets of 6% of revenue or less, well below the reported average (Gartner, 2025).
5. Paid media consumes 30.6% of the average marketing budget, equal to 2.4% of total company revenue (Gartner, 2025).
6. Fifty-nine percent of CMOs said their 2025 budget was insufficient to execute their strategy, down five percentage points from 2024 (Gartner, 2025).
7. Thirty-nine percent of CMOs plan to cut agency budgets in 2025, and 39% plan labor reductions, as AI absorbs work previously handled by outside teams (Gartner, 2025).
8. Twenty-two percent of CMOs said generative AI has already let them reduce reliance on external agencies for creative and strategy work (Gartner, 2025).
9. Small and mid-sized ecommerce brands are projected to grow digital marketing spend 9% to 11% in 2025, even as larger enterprises hold budgets flat (NewMedia, 2025).
10. Typical ecommerce brands direct 7% to 12% of revenue toward marketing, while early-stage brands in growth mode often invest up to 20% (Omnisend, 2026).

Source	Reported budget as % of revenue	Date	Scope or method note
Gartner CMO Spend Survey	7.7% to 7.8%	2025 to 2026	400+ CMOs, mostly companies over $1 billion revenue
The CMO Survey (Deloitte/Duke/AMA)	9.0%	Spring 2026	Broader mix of company sizes than Gartner's sample
Ecommerce-specific benchmark	7% to 12% (up to 20% for early-stage brands)	2026	DTC and growth-stage ecommerce brands only

The gap between Gartner's 7.7% and The CMO Survey's 9.0% comes down to sample composition. Gartner skews toward large enterprises with over $1 billion in revenue, while The CMO Survey spans a wider range of company sizes, and smaller companies tend to report higher marketing spend as a share of revenue.

For an ecommerce brand sizing its own budget, the DTC-specific 7% to 12% range is the more relevant anchor than either enterprise survey.

Marketing Channel Traffic and Revenue Attribution

Knowing which channel actually closes the sale, not just which one brings the most clicks, is what separates efficient budget allocation from guesswork.

11. Retail and ecommerce businesses derive 44.6% of their revenue from organic search, more than any other single marketing channel (Omnisend, 2026).
12. Organic search accounted for 23.56% of ecommerce website traffic in Similarweb's 2025 SEO Benchmark Report, the second-largest channel after direct traffic at 57.66% (Similarweb, 2025).
13. Paid search contributes approximately 19% of ecommerce website visits, and social media drives approximately 14% (NewMedia, 2025).
14. Email accounts for 19.8% of all ecommerce orders, close behind paid search at 19.9% and organic traffic at 21.8% (Lifesight, 2025).
15. Multi-channel ecommerce brands generate 26% more qualified traffic than brands relying on a single primary source (NewMedia, 2025).
16. High-performing ecommerce teams attribute 40% of new-customer growth to a combined SEO, paid search and social strategy rather than any single channel (NewMedia, 2025).
17. Affiliate marketing contributes 12% to 23% of total ecommerce revenue, depending on program maturity (Mailmodo, 2026; NewMedia, 2025).

Traffic or revenue channel	Estimated contribution
Organic search, revenue share	44.6%
Organic search, traffic share	23.6% to 43%
Paid search, traffic share	~19%
Email, share of transactions	19.8%
Social media, traffic share	~14%
Affiliate, revenue share	12% to 23%

The size of the range on organic search traffic share, from 23.6% in Similarweb's benchmark to over 40% in other trackers, comes down to whether AI-referred and branded direct visits get folded into "organic" or counted separately.

Whichever definition a brand uses, the pattern holds across every source: organic and paid search together outweigh every other channel, and no single paid channel comes close to matching email's share of completed transactions.

SEO and Organic Search Marketing Statistics

Organic search keeps compounding for ecommerce brands that invest in it consistently, and 2026 data shows the channel absorbing a new kind of traffic on top of the old kind.

18. The average conversion rate for organic ecommerce leads is 14.6%, meaningfully higher than most paid acquisition channels (Sixth City Marketing, 2025).
19. Ecommerce sites ranking on page one for commercial-intent keywords capture roughly 71% of organic clicks for those terms (NewMedia, 2025).
20. SEO-optimized product pages pull in approximately 24% more non-branded search traffic than generic category pages (NewMedia, 2025).
21. Product pages ranking first or second in search results have 2.72 times more referring domains than pages ranking third through tenth (Sixth City Marketing, 2025).
22. Traffic from AI sources to United States retail sites grew 393% year over year in the first quarter of 2026 (Adobe Digital Insights, 2026).
23. AI-referred traffic converted 42% better than non-AI traffic on US retail sites in March 2026 (Adobe Digital Insights, 2026).
24. AI Overviews appeared on 14% of shopping queries in March 2026, up from a smaller share the year before (SEOprofy, 2026).
25. Non-branded organic search generated approximately 68 times more revenue than ChatGPT referrals across the ecommerce sites studied by Visibility Labs (Visibility Labs, 2026).
26. Non-AI-Overview organic click-through rate declined 41% year over year, settling at 1.62% by September 2025 (Seer Interactive, 2025).
27. AI Overviews reduce clicks to the number-one ranked organic result by 58% (Ahrefs, 2025).
28. Improving Core Web Vitals produced a 33.13% conversion-rate increase for the retailer Rakuten 24 (Rakuten 24 case data, cited via SEO Sherpa, 2026).
29. A one-second delay in mobile page load reduces ecommerce conversion rate by 7.7% (Visionary Marketing, 2026).

Organic search metric	Benchmark
Conversion rate, organic leads	14.6%
Revenue share from organic search	44.6%
Page-one click share, commercial-intent keywords	~71%
AI-referral traffic growth, YoY (Q1 2026)	+393%
AI-referred traffic conversion lift	+42%
Non-AI organic CTR decline, YoY	-41%

AI Overviews are compressing click-through rates for standard organic listings, but the traffic that AI assistants do send converts at a noticeably higher rate than average, so ecommerce brands should judge SEO health on assisted revenue and structured-data visibility, not clicks alone.

Paid Search and Google Shopping Statistics

Paid search still captures the highest-intent shoppers, but rising costs are compressing the margin between what brands spend and what they get back.

30. The average cost per click across all industries on Google Search Ads rose to $70.11 in cost per lead in 2025, up 5.13% from $66.69 in 2024 (Omnisend, 2026).
31. Google Ads cost per click rose 12.88% year over year in 2025 across major industries (WordStream/LocaliQ, 2025).
32. Eighty-seven percent of industries experienced higher Google Ads costs in 2025, driven by increased advertiser competition (WordStream/LocaliQ, 2025).
33. Median return on ad spend across all Google Ads campaigns dropped 10.03% in 2025, even as advertisers spent more per click (Focus Digital/Triple Whale/Varos, 2025).
34. The average ecommerce ROAS for Google Ads sits in the 2:1 to 4.5:1 range, with the median at 2.95x in late 2025 (Omnisend, 2026).
35. Ecommerce and retail advertisers pay $3 to $4 average cost per click on non-brand search terms, cheaper than most other verticals (Quimby Digital, 2025).
36. Retargeting campaigns deliver approximately 27% lower cost per acquisition than cold prospecting campaigns (NewMedia, 2025).
37. Ecommerce brands with mature first-party audience data see roughly 19% lower paid acquisition costs than brands relying on third-party targeting (NewMedia, 2025).
38. Privacy regulation changes, including iOS updates and GDPR enforcement, have degraded paid ad targeting precision by an estimated 40% (Omnisend, 2026).
39. Google Shopping's average cost per click is $0.66, 87% cheaper than standard Search's $5.26 (Foundrycro/Tinuiti, 2026).
40. Shopping campaigns convert at a rate approximately 30% higher than standard text ads (Sixth City Marketing, 2025).
41. The average conversion rate for Google Shopping ads remains under 2%, reflecting competitive, price-sensitive product search (Sixth City Marketing, 2025).
42. Performance Max Shopping campaigns typically deliver 10% to 20% higher ROAS than Standard Shopping campaigns (OwlClaw, 2026).
43. The share of advertisers using Performance Max jumped from 60% in 2024 to 71% in 2025 (Rudys.AI, 2026).

Google Ads metric	Benchmark
Cost per lead, 2025	$70.11, up 5.13% YoY
Cost per click, YoY change	+12.88%
Average ROAS range	2:1 to 4.5:1
Median ROAS, late 2025	2.95x
Google Shopping cost per click	$0.66
Shopping vs. text ad conversion lift	+30%
Performance Max adoption, 2024 vs. 2025	60% to 71%

Rising cost per click and falling median ROAS in the same year means the same paid search budget now buys fewer profitable conversions than it did in 2024.

Shopping campaigns remain the more cost-efficient paid format for product-based ecommerce, since a $0.66 cost per click paired with a 30% conversion lift over text ads still outperforms Search on a blended basis even at a lower per-click conversion rate.

Social Commerce and Paid Social Advertising Statistics

Social platforms have moved from brand-awareness spend to full-funnel commerce channels, though returns vary sharply by platform and category.

44. Social media generates roughly 14% of ecommerce site visits, though social commerce traffic converts around 18% lower than search-driven traffic (NewMedia, 2025).
45. Facebook and Instagram ads average a ROAS between 2.5:1 and 3:1 for ecommerce broadly (Omnisend, 2026).
46. For visual product categories like fashion and home decor, Instagram alone achieves a ROAS of 8.83:1 (Omnisend, 2026).
47. The average ecommerce ROAS across all paid social platforms dropped to 2.87x in 2025, down 4% year over year (rule1/Triple Whale, 2025).
48. Facebook's median ROAS climbed to 2.79x during Q4 peak periods in 2024, compared to 1.86x for the full year (Focus Digital, 2025).
49. Meta's ROAS during Black Friday and Cyber Monday 2024 increased 17% year over year, with conversion rates surging 32% (Focus Digital, 2025).
50. TikTok ads average a ROAS of approximately 1.51 to 2:1, though the platform's ROAS increased 5.85% year over year even as click-through rates fell 12.5% (Triple Whale, 2026; Omnisend, 2026).
51. TikTok Shop grew US ecommerce sales 407% in 2024, reaching $15.82 billion and capturing 18.2% of total US social commerce spend, and as reported by CNBC, sellers and retailers have kept flocking to the platform even under the threat of a US ban (Omnisend, 2026; CNBC, 2024).
52. TikTok Shop's share of US social commerce spend is projected to reach 24.1% by 2027 (Omnisend, 2026).
53. TikTok's average cost per mille fell 28.48% year over year to $4.08, remaining cheaper than Meta's $15.06 median (Triple Whale, 2026).
54. Short-form video campaigns generate roughly 1.7 times higher click-through rates than static social ads (NewMedia, 2025).
55. Advantage+ Shopping campaigns with broad targeting outperform manually targeted Meta campaigns by 15% to 25% in ROAS (Meta Q3 2025 Marketing Summit data, cited via The Jonas Agency, 2026).

Platform	Average ROAS
Instagram, visual product categories	8.83:1
Facebook and Instagram, general	2.5:1 to 3:1
Cross-platform ecommerce average	2.87x, down 4% YoY
Google Ads, ecommerce	2:1 to 4.5:1
TikTok Ads	1.51x to 2:1

Paid social ROAS figures diverge by as much as 4 times depending on which report and which quarter is cited, largely because Q4 holiday performance runs well above the annual average and category margins change what counts as a "good" number.

A fashion brand quoting an 8.83:1 Instagram ROAS and an electronics retailer quoting a 2.5:1 Facebook ROAS can both be performing exactly as expected for their category.

Email Marketing Statistics

Email remains the highest-ROI channel in ecommerce, and the gap between automated and broadcast performance keeps widening rather than closing.

56. Email marketing returns $36 to $42 for every $1 spent across most digital marketing benchmarks (Litmus and DMA, 2025 to 2026).
57. Retail, ecommerce and consumer goods brands specifically average $45 per $1 spent, above the cross-industry figure (Litmus, 2026).
58. Omnisend customers generated approximately $79 in ecommerce revenue for every $1 spent across email, SMS and push combined in 2025, an omnichannel rather than email-only benchmark (Omnisend, 2026).
59. The average ecommerce email open rate is 18.20% (Lifesight, 2025).
60. Average click-through rate for ecommerce emails sits between 2% and 3%, though campaign email click rates fell to 1.22% in 2024 (Lifesight, 2025; Omnisend, 2026).
61. Average click rate across all industries reached 2.09% in 2025, up from 2.00% in 2024 (MailerLite, 2025).
62. Ecommerce email campaigns convert at approximately 2.5% on average (Lifesight, 2025).
63. Ecommerce emails reach a deliverability rate of 96%, with a bounce rate of 0.69% and a spam complaint rate of 0.02% (Lifesight, 2025).
64. Email traffic accounts for 9% of total traffic on ecommerce websites (Lifesight, 2025).
65. Automated emails account for just 2% of total email volume but generated 37% of all email-driven ecommerce sales in 2024 (Omnisend, 2026).
66. Automated emails converted 2,361% better than standard campaign emails, with 52% higher open rates and 332% higher click rates (Omnisend, 2026).
67. Klaviyo's ecommerce data shows automated flows generate approximately 41% of email revenue from just 5.3% of sends (Klaviyo, 2026).
68. Welcome emails achieve an 83.6% average open rate, the highest of any automated email type (Omnisend, 2026).
69. Cart abandonment emails achieve an average conversion rate of 18.64%, contributing approximately a 4.43% sales boost across ecommerce sectors (Lifesight, 2025).
70. Sending a cart abandonment email within one hour of abandonment converts at 6.33%, compared with lower rates for delayed sends (Lifesight, 2025).
71. Only 50% of the top 100 ecommerce businesses deploy cart abandonment emails at all, despite the return (Lifesight, 2025).
72. Segmented email campaigns generate a 27.6% higher open rate and 11.4% higher click rate than non-segmented sends (Lifesight, 2025).
73. Only 57% of the top 100 ecommerce businesses send segmented emails to newly registered users (Lifesight, 2025).

Ecommerce email metric	Benchmark
Average open rate	18.20%
Average click-through rate	2% to 3%
Average conversion rate	~2.5%
Deliverability rate	96%
Automated email share of revenue (from 2% of sends)	37%
Welcome email open rate	83.6%
Cart abandonment email conversion rate	18.64%

Source	Reported email ROI per $1 spent	Date	Scope or method note
Litmus	$36	2025	Cross-industry average, all email types
DMA (UK Marketer Email Tracker)	$42	2025	Different survey base than Litmus, UK-weighted
Litmus, retail and ecommerce specifically	$45	2026	Retail and ecommerce vertical only
Omnisend	$79	2025	Combined email, SMS and push, not email alone

The $36 to $79 spread on email ROI is not four contradictory numbers so much as four different definitions of "email."

The lower figures isolate email-only campaigns across all industries, the $45 figure narrows to retail specifically, and the $79 figure blends in SMS and push notifications, which is why it should never be quoted as an email-only benchmark.

SMS Marketing Statistics

SMS has moved from an experimental add-on to a measured channel with its own automation-versus-campaign performance gap, mirroring what happened in email years earlier.

74. Omnisend's analysis of 321 million SMS messages sent by 150,000 ecommerce brands found standard SMS campaigns convert at 0.12% (Omnisend, 2026).
75. Standard SMS campaigns recorded a 12.39% average click-through rate across the same dataset (Omnisend, 2026).
76. SMS campaigns achieved 96.6% deliverability across the 321-million-message dataset (Omnisend, 2026).
77. Automated SMS messages reached a 20.32% click-to-sent rate, well above standard campaign performance (Omnisend, 2026).
78. Automated SMS converted at 0.77%, more than six times the 0.12% campaign average (Omnisend, 2026).
79. Each automated SMS message generated $0.74 in revenue on average, compared with $0.15 for a standard campaign message (Omnisend, 2026).
80. SMS send volume grew 40% year over year in 2025, following a 31% increase in 2024 (Omnisend, 2026).
81. Sixty-seven percent of ecommerce businesses planned to increase their SMS marketing budgets in 2025 (Omnisend, 2026).
82. Only 39% of online retailers have adopted SMS as a marketing channel, according to eMarketer, leaving a wide adoption gap relative to email (eMarketer, cited via LaunchMyStore, 2025).
83. SMS generates approximately 2.4 times higher click-through rate than email for time-sensitive campaigns like flash sales (NewMedia, 2025).
84. SMS cart recovery flows retrieve approximately 11% to 15% of abandoned checkouts, complementing email recovery sequences (NewMedia, 2025).

SMS metric	Standard campaign	Automated
Click rate	12.39%	20.32% (click-to-sent)
Conversion rate	0.12%	0.77%
Revenue per message	$0.15	$0.74
Deliverability	96.6%	96.6%

The automation gap in SMS is proportionally even larger than the one in email: automated messages convert at more than six times the rate of standard campaigns and generate nearly five times the revenue per message.

Brands still running SMS as a broadcast-only channel are leaving the highest-performing part of the channel unused.

Influencer and Affiliate Marketing Statistics

Influencer spend keeps growing faster than overall marketing budgets, and 2026 data shows performance improving fastest at the smaller end of the creator scale.

85. The global influencer marketing industry is projected to reach $32.55 billion by the end of 2025, up from $24 billion in 2024 (Influencer Marketing Hub, cited via Social Snowball, 2025).
86. Average annual influencer marketing budgets increased 171% year over year between 2024 and 2025 (CreatorIQ, cited via Dash, 2026).
87. Some brands now direct 20% to 50% of total marketing spend into influencer marketing, even as overall budgets stay flat at 7.7% of revenue (CreatorIQ, cited via Dash, 2026).
88. Average influencer marketing ROI is $5.20 for every $1 spent, though top-performing campaigns reach $18 to $20 per dollar (Influencer Marketing Hub, 2025).
89. Micro-influencer campaigns with 50,000 to 100,000 followers saw conversion rates rise 46% year over year to 1.3% (Captiv8, cited via EMARKETER, 2025).
90. Nano-influencer campaigns under 50,000 followers saw revenue per click jump 74% year over year, the largest gain of any tier, with average order value reaching $193 (Captiv8, cited via EMARKETER, 2025).
91. Macro-influencer conversion rates improved from 0.45% to 0.7% as ad standardization on larger accounts matured (Captiv8, cited via EMARKETER, 2025).
92. Seventy-three percent of brands say they prefer micro and mid-tier influencers over larger accounts, citing stronger engagement-to-cost ratios (Later, 2025).
93. Creator-driven affiliate revenue is projected to reach $1.3 billion in 2025, an 86% increase from 2022 (Impact.com/Acceleration Partners, 2026).
94. Influencer-led ecommerce traffic converts roughly 21% to 22% better than standard paid social campaigns in creator-driven categories (NewMedia, 2025).
95. Ecommerce brands blending influencer and affiliate efforts see up to a 46% increase in affiliate-driven sales (DesignRush, 2026).
96. Influencers and affiliate marketers were responsible for approximately 20% of US ecommerce revenue on Cyber Monday 2024 (DesignRush, 2026).
97. Shopify reports affiliate campaigns deliver an average ROAS of 12:1, well above most paid advertising channels (Shopify data, cited via DesignRush, 2026).

Influencer tier	Conversion rate change	Other tier-specific gain
Nano (under 50K followers)	Not separately reported	Revenue per click +74% YoY; AOV $193
Micro (50K to 100K followers)	+46% YoY to 1.3%	Established as the engagement sweet spot
Macro (500K+ followers)	0.45% to 0.7%	Improving via ad standardization

The tier-by-tier data shows influencer performance improving across the board in 2025, but for different reasons at each level: nano accounts are winning on revenue per click as niche trust compounds, micro accounts are winning on conversion rate as brands concentrate spend in that tier, and macro accounts are winning mainly because ad formats have caught up with their reach.

Conversion Rate and AI Personalization Statistics

Conversion rate optimization is one of the highest-leverage investments in ecommerce marketing, and AI-driven personalization is now the fastest-growing lever inside that category.

98. Average ecommerce conversion rates in 2025 range from 2.1% to 3.4% across most product sectors (NewMedia, 2025).
99. Pages that load in under two seconds achieve the highest ecommerce conversion rates, and every additional second of delay costs approximately 7% in completed purchases (Mailmodo/NewMedia, 2025).
100. Returning visitors convert 2.3 to 2.4 times better than first-time visitors (NewMedia, 2025).
101. Product listings featuring customer reviews drove 38% higher conversion rates for electronics and appliances, and 23% higher conversion for clothing, compared to listings without reviews (Sixth City Marketing, 2025).
102. Ecommerce businesses tracked a 144% conversion rate increase when users actively engaged with review content on product pages (Sixth City Marketing, 2025).
103. Mobile conversion rates run 30% to 40% lower than desktop on average, with mobile averaging 2% against desktop's 3% (NewMedia/Mailmodo, 2025).
104. Seventy-nine percent of all Shopify traffic arrives via mobile, yet mobile cart abandonment reaches 77.8%, compared with 67.1% on desktop (Sixth City Marketing, 2025).
105. McKinsey's 2024 research found personalization can drive up to a 15% revenue uplift and a 30% increase in marketing efficiency for ecommerce businesses (McKinsey, 2024).
106. Companies that grow fastest derive 40% more revenue from personalization than average performers (McKinsey, cited via Envive, 2026).
107. Personalization improvements can lift marketing ROI by 10% to 30% by reducing waste in broad, untargeted campaigns (McKinsey, cited via Envive, 2026).
108. Product recommendation engines can drive up to 31% of ecommerce site revenue in sessions where shoppers engage with them (Barilliance, 2026).
109. Amazon generates 35% of its purchases from personalized recommendations, the widely cited industry benchmark for recommendation-driven revenue (Barilliance, cited via Envive, 2026).
110. Ecommerce brands using personalized product recommendations generate roughly 11% higher conversion rates than those without (NewMedia, 2025).

Ecommerce vertical or segment	Conversion rate
General ecommerce, 2025 range	2.1% to 3.4%
Organic ecommerce leads	14.6%
Google Shopping ads	Under 2%
Mobile average	~2%
Desktop average	~3%
Returning visitors vs. first-time	2.3x to 2.4x higher

The consistent finding across every personalization study cited here, regardless of who ran it, is that the revenue gain concentrates in sessions where a shopper actually engages with a personalized element.

Installing a recommendation engine without driving engagement with it captures none of the 15% to 31% upside these figures describe.

Customer Acquisition Cost and Marketing ROI Statistics

Rising acquisition costs are the defining pressure in ecommerce marketing right now, and they make channel-level ROI numbers more important than they were even two years ago.

111. Average ecommerce customer acquisition cost sits between $68 and $84 across categories, up 40% since 2023 (Mobiloud/First Page Sage, 2025 to 2026). According to Wikipedia's overview of the metric, customer acquisition cost is typically weighed against customer lifetime value to judge whether an acquisition channel is actually profitable, not just cheap on a per-click basis.
112. The historical trend is sharper still: the average cost to acquire a new ecommerce customer grew from $9 in 2013 to $29 in 2022, a 222% increase over nine years (LoyaltyLion, citing industry research, 2025).
113. Referred customers carry 16% higher lifetime value than non-referred customers and are four times more likely to refer others themselves (Mobiloud, 2026).
114. Influencer-generated content delivers roughly 30% lower cost per acquisition than brand-produced content in comparable campaigns (Mobiloud, 2026).
115. Brands investing consistently in SEO report roughly 28% lower blended CAC over time, as organic traffic compounds without proportional cost increases (NewMedia, 2025).
116. Customers acquired through email deliver roughly 20% higher lifetime value than customers acquired through paid social alone (NewMedia, 2025).
117. SEO delivers an average ROI of approximately $7.48 per dollar invested, a 748% return over a 12-month horizon (Omnisend, 2026).

How These Statistics Were Compiled

Every figure in this article was verified against the most recently published version of its source rather than pulled from memory or a search snippet.

The source hierarchy prioritized primary releases from research organizations such as Gartner, McKinsey, Omnisend, Similarweb, Litmus, DMA, Klaviyo and EMARKETER, followed by established trade press reporting that names its primary source.

No competitor listicle was cited as a source. Figures older than 2023 appear only where the historical comparison is the point, most notably the 2013-to-2022 customer acquisition cost trend, and are flagged as such in the sentence.

Where credible sources disagreed, such as marketing budget percentage of revenue or email ROI per dollar, this article shows the range with each source and its scope named rather than averaging the figures or picking one silently.

This page was last reviewed in September 2026 and will be updated as newer benchmark reports are published.

Conclusion

Three patterns run through this data. First, budgets have stopped shrinking but have not grown either, which means every channel now has to justify its share of a fixed pool rather than a growing one.

Second, the gap between automated and manual execution, whether in email, SMS or paid social targeting, keeps widening, and the brands capturing outsized returns are the ones investing in that automation layer rather than broadcast campaigns.

Third, acquisition costs are rising faster than most other marketing line items, which raises the relative value of every channel, like organic search, email and referrals, that produces customers at below-average cost.

For 2026 planning, this points toward the same conclusion from several directions: ecommerce marketing statistics consistently reward channel diversification over single-channel dependency, and they reward measurement discipline enough to know which channel is actually driving the number a brand cares about, rather than the one that is easiest to attribute.

FAQ

What percentage of revenue should an ecommerce business spend on marketing?

Most established ecommerce businesses spend between 7% and 12% of revenue on marketing, while early-stage brands in growth mode often invest up to 20% (Omnisend, 2026). Enterprise-wide surveys like Gartner's report a lower average of 7.7% to 7.8%, largely because their sample skews toward much larger companies with more efficient marketing at scale.

What is the average ROI of email marketing for ecommerce?

Email marketing returns $36 to $42 per $1 spent across most industries, and retail and ecommerce brands specifically average $45 per $1 spent (Litmus and DMA, 2025 to 2026). That makes email the highest-ROI channel measured in this data, ahead of SEO, SMS and paid advertising.

How much does it cost to acquire a customer in ecommerce?

Average ecommerce customer acquisition cost sits between $68 and $84 across categories in 2025 to 2026, up 40% since 2023 (Mobiloud/First Page Sage, 2025 to 2026). Costs vary significantly by product category and acquisition channel, with referral programs and organic search consistently producing the lowest CAC.

What is a good ROAS for ecommerce paid social ads?

Ecommerce ROAS averages 2.87x across paid social platforms as of 2025, though it ranges from around 1.5x on TikTok up to 8.83x on Instagram for visual product categories like fashion (Omnisend, 2026; rule1/Triple Whale, 2025). What counts as "good" depends heavily on product margin, since a 2.5x ROAS can be more profitable than a 4x ROAS in a higher-margin category.

What do ecommerce marketing statistics show about SEO investment?

Yes. Organic search generates 44.6% of ecommerce revenue by channel and delivers a 14.6% average conversion rate, both higher than most paid channels (Omnisend, 2026; Sixth City Marketing, 2025). SEO also produces an estimated $7.48 return per dollar invested over a 12-month horizon, and that return compounds over time rather than stopping when spend stops, unlike paid media.

How much does SMS marketing convert compared to email?

Standard SMS campaigns convert at 0.12% on average, well below email's approximately 2.5% conversion rate, but automated SMS messages convert at 0.77%, more than six times the standard campaign rate (Omnisend, 2026). SMS performs best as a complement to email for time-sensitive promotions and cart recovery rather than as a replacement for it.

Do micro-influencers really outperform larger influencers for ecommerce brands?

On conversion rate, yes: micro-influencer campaigns saw conversion rates rise 46% year over year to 1.3% in 2025, while macro-influencer conversion rates sit at 0.7% (Captiv8, cited via EMARKETER, 2025). Larger influencers still deliver more total reach, so the right choice depends on whether the campaign goal is conversion volume or broad awareness.

How much does AI personalization improve ecommerce conversion rates?

McKinsey's research found personalization can drive up to a 15% revenue uplift and a 30% increase in marketing efficiency for ecommerce businesses, with the fastest-growing companies deriving 40% more revenue from personalization than average performers (McKinsey, 2024). The gain concentrates specifically in sessions where shoppers engage with the personalized element, such as clicking a product recommendation.
