At a glance
What we observed in this category
Parexel leads the pharmacovigilance services category with a composite score of 16.2, ahead of IQVIA and Cognizant who both sit at 12.5. The gap matters because Parexel's advantage is driven almost entirely by citation share (25.0%) rather than visibility alone, suggesting AI treats it as a more authoritative reference point. IQVIA, despite holding the top rank in the prior period, has shed 25.0 visibility points and dropped to second, making the lead position more contested than the current snapshot implies.
Freyr Solutions presents the sharpest divergence between visibility and citation in this dataset: 0.0% visibility but a 25.0% citation rate, matching Parexel's citation figure. This means Google AI Mode names Parexel and Freyr equally often as sources but surfaces Freyr in far fewer overall query responses. Accenture shows the inverse pattern, achieving 12.5% visibility with 0.0% citations, indicating it appears in AI summaries without being pulled as a reference source. These two cases confirm that being named and being trusted are distinct signals in this category.
Google AI Mode is the dominant engine across all 20 brands in this audit, with no other engine recorded as a top performer for any brand. The top cited sources in the category are dominated by third-party aggregators and market research platforms, including mordorintelligence.com, sphericalinsights.com, and marketgrowthreports.com, alongside community platforms like linkedin.com and quora.com. No brand's own domain appears in the cited sources list, which indicates AI is anchoring pharmacovigilance answers on secondary and aggregator content rather than vendor-owned material.

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 →
