At a glance
What we observed in this categoryauto-generated
Yotpo holds the top composite score at 23.8, built on a citation rate of 50.0% despite visibility of only 12.5%. ReferralCandy and Referral Factory both score 21.2 and share identical visibility (25.0%) and citation (12.5%) figures, meaning the gap between first and second place is driven entirely by citation authority rather than raw mention frequency. That citation gap is material: Yotpo is cited four times more often than either of its nearest rivals, signalling that AI treats it as a more trustworthy source even when it appears less frequently in responses.
ReferralCandy and Referral Factory illustrate how a brand can achieve high visibility without proportional citation trust. Both appear in 25.0% of responses, well above the category average of 5.0%, yet their citation rate of 12.5% matches the category average of 7.5% only modestly. Friendbuy sits at 12.5% visibility but earns zero citations, showing that named presence alone carries no guarantee of sourcing. Extole, Viral Loops, and ReferralHero each earn 12.5% citations despite zero visibility, the inverse pattern.
Every brand in the dataset lists Google AI Mode as its top engine, confirming that this category's AI visibility landscape is essentially a single-engine story. The top cited external sources include tremendous.com, youtube.com, klaviyo.com, and reddit.com alongside brand-owned domains like yotpo.com, firstpromoter.com, referralcandy.com, and referral-factory.com. The presence of reddit.com and youtube.com in that source list suggests Google AI Mode is anchoring partly on community and video content rather than exclusively on vendor or review-site material.

How to read this 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.
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.
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.
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 30 days and refresh this page automatically.
