When buyers ask AI engines about leading SEO agencies, WebFX stands out as the leader with a visibility percentage of 25.0. Other top brands in this category include Searchbloom and Victorious, both of which frequently appear as top recommendations. WebFX is especially notable for its 37.5 percent citation rate, securing its position as the most recognized choice.
The current rankings reflect the sources AI engines frequently cite, with heavy reliance on domains like outerboxdesign.com, clutch.co, and youtube.com. Many of these are aggregator or review sites which offer a broad view and comparison of services, boosting the visibility of brands like WebFX by providing consistent and comprehensive evaluations to the AI.
For buyers, this list is a guide to which SEO agencies the AI engines favor, often due to recent reviews or in-depth third-party validations. When choosing from this list, consider each brand's topical authority within specific subcategories of SEO, ensuring their strengths align with your needs for specialized services.
At a glance
What we observed in this category
WebFX and Searchbloom share the top composite score of 28.8, each recording 25% visibility and 37.5% citation rates against a category average visibility of just 6.2% and average citation of 9.4%. That gap is substantial: the leading pair are appearing and being cited at roughly four times the category norm. Victorious sits third at a composite of 26.2, so the top three are tightly bunched, but the drop to OuterBox at 22.5 and NP Digital at 17.5 marks a more meaningful step down in overall AEO performance.
The most telling divergence in this category is between brands the AI names and brands it actually cites as sources. Victorious has 37.5% visibility, the highest single visibility figure in the set, yet records 0% citation, meaning Google AI Mode surfaces it in answers but does not link back to it. OuterBox is the mirror case: 0% visibility but 75% citation, making it the most-cited brand in the data while barely appearing in generated answers. First Page Sage and StudioHawk follow the same citation-without-visibility pattern, signalling a clear split between narrative presence and reference authority.
Google AI Mode is the dominant engine across every brand in this dataset, with no outliers anchoring to ChatGPT or Perplexity. Third-party sources feature prominently in the top cited list alongside brand domains: clutch.co, designrush.com, and reddit.com all appear, which means AI-generated answers in this category draw on review aggregators and community discussion, not solely agency websites. OuterBox's own domain (outerboxdesign.com) appears first in that cited-sources list, reinforcing its unusually high citation rate despite its visibility decline from rank 1 to rank 4.

How to read this AEO ranking
Four things worth knowing before you act on the numbers above. These are the same definitions across every industry page — for category-specific observations, see the What we observed section above (where available) and the per-brand insights inline in the ranking.
Visibility = being named
A brand's visibility % is the share of AI answers that mention it by name in the response prose. This is who AI engines actively recommend to the buyer. More on visibility →
Citation rate = being trusted
Citation rate is the share of AI answers that include the brand's domain as a clickable source link. This is what the AI treats as authoritative evidence, different from being named. More on citation rate →
Top engine differs by brand
The "top engine" column shows which AI surface each brand performs best on. Big gaps between a brand's score across engines usually points to specific content or schema gaps. How AI engines pick sources →
