The transparency map: SEO firms publish rates 87% of the time, Demand Gen firms 60%
Across the 1,738 US growth vendors with public engagement data in The Wall’s index, rate-disclosure rates cluster tightly at the top and fall off sharply at the bottom — and where a category lands on the scale tells buyers something more useful than the rates themselves.
Rate transparency in the US growth-vendor market is not evenly distributed. Across the ten categories in The Wall's index, the share of firms with public engagement data that publish an hourly rate ranges from 87.4% at the top to 0% in one specific corner. The full ranking, computed against the subset of listings in each category that publish any provider data at all:
| Category | Rate disclosure | Minimum project disclosure |
|---|---|---|
| SEO | 87.4% | 95.6% |
| Creative Strategy | 86.5% | 95.8% |
| Content Marketing | 81.6% | 93.1% |
| Marketing | 80.9% | 94.1% |
| Social Media Marketing | 78.7% | 97.3% |
| Automation | 75.0% | 95.0% |
| Thought Leadership | 68.0% | 90.2% |
| Demand Gen | 60.0% | 93.3% |
| AI Marketing | 0%* | 0%* |
| Sales | —* | —* |
* AI Marketing and Sales are compiled from curated sources rather than public agency-review data; disclosure rates are not comparable.
Why the top of the ranking clusters so tightly
SEO, Creative Strategy, Content Marketing, Marketing, and Social Media Marketing all sit within a seven-point band — 78.7% to 87.4%. These are the categories where the client-services model is fully mature: buyers expect a rate band, sellers know that publishing one pre-qualifies inbound and saves discovery-call time on both sides, and the reference-review platforms these firms use make the disclosure explicit. A firm operating in these categories that doesn't publish an hourly rate is deliberately opting out of a market norm.
Why Thought Leadership and Demand Gen lag
The bottom of the ranking is a signal of a different market shape. Thought Leadership work (68% disclosure) is often priced per-engagement — a book program, a podcast series, a keynote push — rather than per-hour, so an hourly rate is genuinely a poor unit for what's being sold. Demand Gen (60% disclosure) is heavily performance-priced — cost per meeting, cost per SQL, revenue share — and traditional hourly rate cards misrepresent the commercial model.
Buyers reading these numbers should interpret them accordingly: an undisclosed rate in SEO or Marketing is a question worth asking; an undisclosed rate in Thought Leadership or Demand Gen is often just a reflection of how those disciplines commercially operate. What matters is that the firm can articulate some pricing structure by the first substantive conversation — not that it fits the hourly-rate mold.
What "0%" in AI Marketing actually says
AI Marketing's zero-disclosure figure is not a transparency failing. The category is young enough that most of its 34 US listings are compiled from curated industry sources rather than from the agency-review platforms where structured engagement data lives. That's information too: a buyer evaluating an AI-marketing firm should expect to rely more on direct evaluation and less on public engagement data than in any other pillar of the index.
How this was computed. Figures are computed from The Wall's index of 2,286 approved, US-based, machine-verified-live listings as of August 3, 2026. Engagement data (rates, minimum project sizes, team sizes, founding years, ratings) are provider-declared figures published on public Clutch profiles and are present for 1,738 of the 2,286 listings; percentages of "disclosed" values exclude listings that publish no figure.
