Market demand and agency growth
Two numbers matter here: how much clients spend on advertising, and how much of that turns into agency revenue growth. WARC covers advertiser spend; Promethean Research covers agency performance.
$1.17T
WARC says the global ad market is on track to reach $1.17 trillion in 2025.
WARC forecast 7.4% growth for 2025. For agencies, where the money goes matters more than the total.
90.3%
Nine in ten ad dollars now go to online-only platforms.
WARC puts 90.3% of 2025 ad spend into online-only platforms. Digital execution and measurement are now the baseline for any marketing agency.
$274B
Paid search alone is forecast to reach $274 billion in 2026.
WARC expects paid search growth to slow as people search on platforms like Amazon and TikTok, but it remains one of the largest budget lines agencies manage.
7.5%
Average digital agency revenue growth came in at 7.5% in 2025.
That is up from 5% in 2024, the low point, but about half the 13% average Promethean recorded from 2015 to 2020 (2024 report). Its 2026 report puts the average over the last five years at 12%. Large agencies grew 2.7x faster than small agencies in 2025.

7.1%
The average digital agency allocates 7.1% of revenue to sales and marketing, including salaries and media spend.
Promethean says this level of investment, while common, usually falls short of the growth targets agencies set. Its 2026 report gives 7%. Most agencies still get most of their leads from referrals.
Source: Promethean Research, 2025 Digital Agency Industry Report
AgencyPro’s reading: ad spend keeps growing, but agency growth has not kept pace. In Promethean’s 2026 data, agencies that cut services in 2025 grew about 13% and averaged 30% net margins, while agencies that added services averaged 10%.
Agency count, size and specialization
The agency market is large and made up mostly of small firms. Most of them now position as specialists.
| Agency size (FTEs) | Share of agencies | Typical positioning (AgencyPro note) |
|---|---|---|
| Under 10 FTEs | 59% | Owner-operator studios; highest average net margins |
| 10-49 FTEs | 29% | Specialist shops building management layers |
| 50-249 FTEs | 9% | Mid-market firms with formal ops and BD functions |
| 250+ FTEs | 2% | Large independents and network-adjacent shops |
Source: Promethean Research, 2025 Digital Agency Industry Report. Promethean presents these shares with its count of more than 50,000 agencies in the United States and Canada (its observational data set, not its survey sample); together, 88% have fewer than 50 FTEs. The 2026 report, which adds Mexico and counts 71,000+ North American agencies, gives 87%. The positioning column is AgencyPro’s description, not Promethean data.
84%
The overwhelming majority of digital agencies identify as specialists.
Promethean reported that 84% of agencies identified as specialists in 2024, with the trend leveling off at that point. 77% specialize by service mix and 57% by industry. Its 2026 Digital Agency Growth Guide gives 86% for 2026, a different survey year, so the two figures are not a measured change.

59% / 29%
Promethean sizes the market at 59% under 10 FTEs and 29% at 10 to 49 FTEs.
Only 9% of agencies have 50 to 249 FTEs and 2% have more. Most owners should benchmark against small peers, not holding-company economics.

71K+
Promethean counts more than 71,000 digital agencies in North America in 2026, up from about 50,000 in its 2024 checks.
The count has grown at a 12% compound annual rate since 2018; adding Mexico this year contributed under 2,000. Worldwide, Promethean identifies more than 200,000 agencies.

54%
The number of digital agencies in the U.S. and Canada grew 54% from 2018 to 2023.
Promethean also notes the share of agencies with 0 to 10 FTEs fell from 73% in 2018 to 64% in 2023, while the 11 to 50 FTE group rose from 21% to 27%. More agencies were created and the average agency got larger.

43%
Specialist agencies grew 43% faster than average in 2024.
Promethean links the gap to shorter sales cycles and easier wins when an agency is seen as the expert in a niche. In 2025, design agencies grew 3x faster than blended agencies.
Source: Promethean Research, 2025 Digital Agency Industry Report
87%
87% of North American digital agencies have fewer than 50 full-time employees.
Blended agencies (design, development and marketing) dominate. Marketing-only agencies make up 19% of the market, development shops 11% and pure design shops 6%.
Source: Promethean Research, Digital Agency Industry Report (2026)
AgencyPro’s reading: benchmark against agencies that look like yours. A 12-person specialist shop should compare itself with other small specialists, not with holding companies or enterprise consultancies.
Service mix and AI adoption
Web development and design are still the most common agency services, but their share is slipping while AI services grow from a small base.
| AI adoption stage | Agencies | Broader enterprise |
|---|---|---|
| Implemented across the business | 34% | 78% using AI in at least one function |
| Actively implementing now | 28% | 71% regularly use gen AI in at least one function |
| AI-related services offered | 17% (up from 10% in 2023) | Not applicable |
Sources: Promethean Research, 2026 State of Digital Services FAQ; McKinsey, The State of AI 2025.
69% / 67% / 60%
Web development, web design, and digital strategy are still the most common agency services.
All three declined from 2023 to 2025: web development from 75% to 69%, web design from 73% to 67% and digital strategy from 68% to 60%.
Source: Promethean Research, 2025 Digital Agency Industry Report
10% -> 17%
AI development and implementation nearly doubled as an agency service from 2023 to 2025.
Promethean tracks AI-related services at 10% of agencies in 2023 and 17% in 2025. It is still a minority service line.
Source: Promethean Research, 2025 Digital Agency Industry Report
34% / 28%
One-third of agencies say AI is already implemented across the business, while another 28% are implementing it now.
Promethean measures AI maturity across eight functions, including coding, design, copywriting and project management. Its 2026 industry report adds that 70% of agencies changed their service mix in 2025.
78%
Across industries, 78% of organizations used AI in at least one business function, up from 72% in early 2024.
From McKinsey’s survey of 1,491 participants in July 2024, published March 2025. Clients use AI in-house too, so agencies need to sell judgment and execution quality, not tool access.
71%
McKinsey says 71% of organizations regularly used gen AI in at least one business function, up from 65% in early 2024.
Client teams can now produce first drafts themselves. Agencies selling content volume face the most pressure; strategy, QA and integration work less so.
AgencyPro’s reading: keep the core services that fund the business. Add AI work where clients already ask for it, and drop services that add complexity without margin.
Methodology notes
- •AgencyPro did not survey agencies for this page and has no original industry data of its own. Every figure is secondary: it summarizes published third-party research and links each figure to its source. Paragraphs marked “AgencyPro’s reading” and the positioning notes in the size table are AgencyPro commentary.
- •Agency counts and long-run figures come from Promethean Research’s 2026 Digital Agency Industry Report, which combines surveys of 1,452 agency leaders, 3,172 employee positions and observational data on 200,000+ agencies. 2025 growth, margin and AI figures come from its 2026 State of Digital Services survey (119 agency leaders, February 2026, 74% US).
- •Size distribution, specialization and service-mix shares come from Promethean’s 2025 Digital Agency Industry Report (2024 data unless stated). Its survey figures come from 1,062 agencies, a sample Promethean says skews toward larger agencies; the size distribution is shown with its separate observational set of 50,302 agencies in the United States and Canada.
- •Agency counts use different populations by year: about 50,000 in the United States and Canada (2025 report), 71,000+ in North America including Mexico (2026 report, which says Mexico added under 2,000) and 200,000+ worldwide. Compare like with like.
- •WARC and McKinsey figures describe the market agencies sell into. They are not agency revenue benchmarks. WARC figures are forecasts built from media-owner and platform data; McKinsey’s figures come from its July 2024 online survey of 1,491 participants across industries.
- •The 54% agency-count growth figure (2018 to 2023) and the 73% to 64% small-shop share come from Promethean’s 2023 Digital Agency Industry Report, now cited directly.
