How AI Search Is Recommending Enterprise SEO Marketing Agencies: Monthly Trends

Executive Summary

WebFX remains the coverage leader in September 2026, but its lead has narrowed. WebFX appears in valid recommendations in 66.1% of September 2026 observations, down 7.7 points from 73.8% in July 2026. This places WebFX 26.7 points ahead of the second-ranked brand, Searchbloom, which holds 39.4% coverage.

September 2026 was a month of significant movement, though no brand rose past its normal variation this period. WebFX, First Page Sage, iPullRank, and Seer Interactive each recorded a significant decline from July 2026 to September 2026. First Page Sage showed the sharpest single-month drop, falling 12.9 points in coverage from 41.8% in August 2026 to 28.9% in September 2026. NoGood was the strongest upward mover, adding 1.1 points sequentially to reach 13.0% coverage, though this gain stayed within normal month-to-month variation.

The category-level change came from a combination of several declines occurring together. WebFX fell 5.8 points from August to September 2026, First Page Sage fell 12.9 points, and Searchbloom fell 5.0 points sequentially. The current benchmark records coverage compressing across several brands at once this month; the data does not establish why multiple brands moved in the same direction.

Each monthly run begins with 800 prompt-surface observations (570 unique questions in September 2026) across the benchmark's defined AI/search surface universe. Of those, 800 mentioned a tracked brand or competitor; 514 were relevant and 286 were irrelevant. The public metrics use the 502 observations that survive both qualification stages. In July 2026, the equivalent run began with 800 observations (574 unique questions), with 446 relevant and 354 irrelevant, producing 446 qualified observations.

Key Findings

Benchmark Context

The report separates the raw collection universe from the qualified analysis set. Brand-level recommendation percentages are calculated within the qualified benchmark set.

The August 2026 run sat between these two months with 455 qualified observations and 800 source prompts.

Benchmark-Level Metrics

AI Recommendation Trend

The category leader held, but the middle of the field compressed as multiple brands moved down from their July 2026 levels.

The coverage table below shows each tracked brand's valid recommendation coverage in July 2026 and September 2026.

Four brands recorded movement beyond normal month-to-month variation from July to September 2026. The rest of the category's movement came from a combination of smaller changes that, taken together, reshaped the competitive spread.

What Changed This Month

WebFX

WebFX held the top position in September 2026 but recorded a significant coverage decline. Its valid recommendation coverage was 73.8% (329 of 446 qualified observations) in July 2026 and 66.1% (332 of 502) in September 2026, down 7.7 points. On a sequential basis, WebFX fell 5.8 points from 71.9% in August 2026.

Presence softened alongside coverage. WebFX was mentioned in 75.1% of September 2026 observations, down from 81.6% in July 2026. Notably, the brand's rank-one rate rose to 29.1% in September 2026 from 24.2% in July 2026.

The distinction to notice is that WebFX is appearing in fewer answers overall but is more likely to be the first name recommended when it does appear. The coverage decline and the rank-one gain are separate signals pointing in different directions.

Highest-priority diagnostic: Which prompt themes drove the coverage decline, and are those the same themes where rank-one frequency rose?

First Page Sage

First Page Sage recorded the largest sequential decline in September 2026, a movement that was significant. Coverage fell to 28.9% (145 of 502 qualified observations) from 41.8% in August 2026, down 12.9 points. From July 2026 to September 2026, the decline was 14.8 points from 43.7% (195 of 446).

Presence fell in parallel. First Page Sage was mentioned in 33.5% of September 2026 observations, down from 48.2% in July 2026. Top-three recommendation rate dropped 9.0 points from 26.9% to 17.9%, and rank-one rate fell 6.3 points from 15.5% to 9.2% over the same period.

The gap between First Page Sage and NoGood narrowed substantially, from a 32.0-point lead in July 2026 to a 15.9-point lead in September 2026. That narrowing is a category-level observation about the middle of the field, not an explanation of cause.

Highest-priority diagnostic: Which surfaces and prompt types drove the September drop, and which competitor now captures the recommendations First Page Sage previously held?

iPullRank

iPullRank recorded a significant decline from July to September 2026. Coverage fell 5.8 points from 16.6% (74 of 446) in July 2026 to 10.8% (54 of 502) in September 2026. The brand was effectively flat between August and September 2026 at 10.8%.

Presence dropped from 16.6% to 13.0% of observations across the period. The absolute counts are small: iPullRank received 54 valid recommendations in September 2026 versus 74 in July 2026. Its rank-one rate stayed essentially flat at 2.8% in September 2026 versus 2.7% in July 2026.

The sharpest movement happened in August 2026, when coverage fell 5.8 points; September was flat. Readers should treat these as two distinct events rather than one continuous slide.

Highest-priority diagnostic: What changed in August 2026 to cut iPullRank's recommendation count, and what kept it flat in September?

Seer Interactive

Seer Interactive also recorded a significant decline from July to September 2026. Coverage fell 6.4 points from 16.8% (75 of 446) in July 2026 to 10.4% (52 of 502) in September 2026. The brand ticked up slightly from August, up 0.7 points from 9.7%.

Presence fell from 16.8% to 11.6% of observations across the period. Rank-one rate held at 1.4%, and net sentiment remained positive at 0.9. The absolute counts are small: 52 valid recommendations in September 2026 versus 75 in July 2026.

Highest-priority diagnostic: Which evidence sources or surface behaviors are associated with Seer Interactive's reduced presence and recommendation counts?

NoGood

NoGood was the category's upward mover in September 2026, though the gain was not beyond normal variation. Coverage rose 1.1 points sequentially from 11.9% in August 2026 to 13.0% (65 of 502) in September 2026. From July 2026 to September 2026, the gain was 1.3 points from 11.7% (52 of 446).

Presence rose from 12.8% to 14.1% of observations over the period. The absolute counts are small: 65 valid recommendations in September 2026. NoGood's rank-one rate was 2.8% in September 2026.

Highest-priority diagnostic: Which prompt themes account for NoGood's added coverage, and is the gain concentrated in one surface or spread across surfaces?

Buyer-Intent Interpretation

Every qualified observation in each month of this series fell into the Brand Recommendation cluster. The benchmark did not generate qualified observations in the Pricing & Value or Multi-Brand Comparison clusters for July, August, or September 2026. The public benchmark therefore shows which agencies win direct recommendations, but it cannot yet answer questions about price positioning, value perception, or head-to-head comparison outcomes across this vertical.

Brand Opportunity Summary

The benchmark identifies where attention is warranted; a company-level analysis is needed to explain why.

Evidence and Interpretation Notes

The aggregate metrics are built from prompt-level observations (query, surface, recommendation outcome, rank, sentiment, and citations where exposed). Company-level analysis can go deeper into prompt, competitor, surface, and evidence patterns. Source presence is not automatically treated as proof of causation.

• Coverage percentages are computed within the qualified benchmark set of 502 observations for September 2026, distinct from the 800 raw prompt-surface observations collected.
• Small-count brands (Avenue Z, iPullRank, Seer Interactive) carry more measurement uncertainty; their movement should be read alongside the absolute counts, not the rate alone.
• Significant movement flags changes beyond normal month-to-month variation; it identifies changes worth investigating, not their cause.

Next Step

The Public Benchmark Shows Where a Brand Is Winning or Losing. A Company-Level Audit Shows Why.

Beneath each aggregate percentage are the questions that matter commercially: which high-intent prompts are won and lost, which competitor takes the recommendation when a brand loses, what attributes AI systems associate with each option, and which external sources shape those answers. A benchmark movement is the signal to investigate, not the explanation itself.

A company-specific AI visibility audit maps those prompt, surface, competitor, ranking, sentiment, and evidence-source patterns into a prioritized visibility strategy. It turns the benchmark's directional signals into a concrete picture of where a brand holds authority, where it is vulnerable, and what is driving the difference.
