At a glance
What we observed in this category
Coupa holds the top composite score in this category at 41.2, ahead of SAP Ariba's 26.2, despite both sharing an identical visibility rate of 37.5 percent. The gap is driven entirely by citation: Coupa is cited in 50 percent of responses while SAP Ariba records zero citations. For a category where the average citation rate across 20 brands is just 11.9 percent, Coupa's citation dominance is the primary reason it leads, and SAP Ariba's zero citation rate is a significant AEO weakness given its otherwise equal named visibility.
Precoro is the sharpest example of visibility and citation diverging. It currently holds zero visibility yet a 75 percent citation rate, the highest in the category, placing it third overall on composite score. Stampli and Zycus show the same pattern at smaller scale, each scoring zero visibility but 25 percent citation. This split suggests AI responses in this category regularly trust and link to these brands as sources without naming them as featured recommendations, a meaningful distinction for understanding AEO performance here.
Google AI Mode is the dominant engine across all ten ranked brands, with every brand recording it as their top engine, confirming the AI citation environment in this category is almost entirely shaped by one platform. Among the top cited sources, precoro.com and coupa.com appear alongside third-party sites including youtube.com, g2.com, pivotapp.ai, and fraxion.biz. The presence of review and niche comparison sites in the citation pool indicates AI responses are anchoring on external editorial content, not solely vendor-owned domains.

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 →
