At a glance
What we observed in this category
PageProof leads the online proofing software category with a composite score of 56.2, ahead of Ziflow at 52.5. Both share identical visibility at 37.5%, but PageProof's 100% citation rate versus Ziflow's 87.5% creates a meaningful gap at the top. The category average visibility sits at just 9.4%, meaning these two brands are appearing at four times the typical rate. That concentration at the top suggests Google AI Mode is consistently anchoring its responses around a very small shortlist.
Approval Studio presents the sharpest divergence between citation and visibility in the dataset. It holds a 100% citation rate despite 0% visibility, placing it third overall with a composite score of 30.0. Conversely, Filestage and ReviewStudio both achieve 37.5% visibility but record 0% citation, producing identical composite scores of 26.2. This split reveals that AI Mode names some brands frequently without linking to them, while citing others as sources even when they do not appear in direct responses.
Google AI Mode is the top engine for every brand in the dataset without exception, indicating no meaningful signal from other engines in this category. The top cited sources include pageproof.com, ziflow.com, and approval.studio as brand-owned domains alongside third-party authorities such as gartner.com, g2.com, and youtube.com. The presence of simple.io and guideflow.com in the citation list, neither of which appear as ranked brands, suggests the AI is drawing on review or tutorial content beyond brand homepages to construct its answers.

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 →
