At a glance
What we observed in this category
Chief Outsiders holds a commanding lead in this category, with a visibility score of 25.0% against a category average of just 1.2%, and a citation rate of 50.0% that is ten times the average of 5.0%. The gap between rank one and rank two is substantial: CMOx sits at 0.0% visibility despite a 37.5% citation rate. That spread of 25 percentage points in visibility between first and second place signals that Google AI Mode is concentrating named presence very narrowly at the top.
A notable divergence between visibility and citation exists in this data. CMOx carries a 37.5% citation rate with zero visibility, meaning Google AI Mode references it as a source but does not surface it in direct brand mentions. Authentic Brand shows the same pattern at 12.5% citation and 0.0% visibility. This suggests the AI treats some brands as supporting evidence rather than featured answers, a distinction that matters for how buyers actually encounter these firms.
The top cited sources in this category are dominated by third-party and aggregator domains, with linkedin.com, youtube.com, toptal.com, and growtal.com all appearing alongside chiefoutsiders.com as the only direct brand domain in the list. Geisheker.com, thegrowthsyndicate.com, and rightsideup.com also feature, indicating Google AI Mode anchors its fractional CMO responses on directory-style and platform content rather than on individual firm websites. All recorded activity in this audit is attributed to a single engine, Google AI Mode.

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 →
