When it comes to Identity verification APIs, AI engines often point to Veriff as the leader in the field, with a visibility percentage of 37.5. Other notable mentions include Persona and Didit, making them top choices for those seeking well-regarded brands in the Security category.
The rankings are significantly influenced by data pulled from several key domains, such as vouched.id and didit.me. If these sources are aggregator or review sites, it means that AI references consolidate various reviews and expert opinions, bolstering the credibility of the rankings seen here.
For potential buyers, noting how AI engines prioritize recent reviews and third-party validations can be crucial. When selecting a brand from the list, consider platforms with high topical authority in Identity verification, as they are more likely to be validated by AI through comprehensive, up-to-date information.
At a glance
What we observed in this category
Veriff leads the identity verification APIs category with a composite score of 41.2, nearly double Persona's 25.0 in second place. That gap is significant because the category average visibility sits at just 8.1 percent, meaning Veriff is performing at more than four times the typical brand in this space. Persona's rise from rank 8 to rank 2 in a single period, with visibility jumping from 0 to 25 percent, signals the standings are still actively shifting rather than settled.
Didit presents the sharpest divergence between visibility and citation in the dataset. Its visibility is 0.0 percent yet its citation rate is 75.0 percent, the highest citation figure of any brand in the top 10. This means AI is pulling Didit's domain as a trusted source without naming it directly in responses. Onfido shows the inverse pattern, with 25 percent visibility and 0 percent citation, suggesting it is named in answers but its own domain is not being cited as a reference.
Google AI Mode is the top engine for every brand in this category without exception. The top cited sources list is dominated by smaller or adjacent domains including vouched.id, didit.me, in.springverify.com, ondato.com, and regulaforensics.com, alongside review aggregator g2.com. This suggests Google AI Mode is anchoring its answers on third-party comparison and specialist content rather than pulling primarily from the major vendors' own domains, which explains why brands like Didit earn high citation rates despite near-zero direct visibility.

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 →
