At a glance
What we observed in this category
MadCap Software Services holds the only meaningful AI visibility position in this category, with a 12.5% visibility score and a 75.0% citation rate against a category average visibility of just 0.6%. Its composite score of 31.2 dwarfs the second-ranked brand, 3di Information Solutions, which scores 3.8. That gap is not marginal. It signals that Google AI Mode has effectively anchored the entire category around a single brand, leaving 18 of 20 tracked brands with zero composite score.
3di Information Solutions presents a notable divergence: it holds a 12.5% citation rate despite 0.0% visibility, meaning Google AI Mode references it in answers without surfacing it as a named recommended brand. Ranks 3 through 10, including recognisable names like Scriptorium, Acrolinx Services, and Write the Docs, show zero on both metrics. This pattern suggests that being known in the industry does not translate to AI citation or visibility without specific content signals that the engine is rewarding.
The top cited sources list reveals that Google AI Mode is anchoring heavily on community and freelance platforms such as reddit.com, upwork.com, and youtube.com alongside specialist sites like timelytext.com, devdocs.work, and heretto.com. Madcapsoftware.com appears directly in the cited sources list, which aligns with its dominant citation rate of 75.0%. The presence of reddit.com and medium.com suggests the engine is drawing on user-generated and editorial content rather than purely brand or vendor domains when constructing answers in this category.

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 →
AEO rankings move month to month
AI engines re-crawl and re-rank on shorter cycles than classical search. We re-audit every brand on this list at least every 90 days and refresh this page automatically. How AI search ranking works →
