At a glance
What we observed in this category
Justworks leads the PEO services category with a visibility score of 62.5%, more than double the 25.0% held by third-ranked Rippling PEO and six times the category average of 10.0%. This gap is significant because it reflects a concentrated AI narrative: Google AI Mode surfaces Justworks in the majority of relevant queries while most of the 20 tracked brands sit at 0.0% visibility. Justworks rose from rank 4 to rank 1 with a visibility delta of 50.0 percentage points, the largest single-period movement in the dataset.
The most striking divergence between visibility and citation sits with Rippling PEO. It holds only 25.0% visibility, yet its citation rate is 75.0%, the highest in the category by a wide margin. Justworks and Insperity show the inverse pattern: both have 0.0% citation despite visibility of 62.5% and 37.5% respectively. This means Google AI Mode names Justworks and Insperity frequently in responses but does not anchor those claims to their own domains, whereas Rippling is cited as a trusted source even when it appears less often.
The top cited sources list reveals that Google AI Mode draws heavily on third-party editorial and aggregator sites including businessnewsdaily.com, business.com, forbes.com, and uschamber.com. Rippling.com is the only brand domain appearing directly in the cited sources list, which explains its anomalously high 75.0% citation rate. Specialist directories such as peo-marketplace.com and alphaapexgroup.com also appear, suggesting AI responses in this category are grounded in review and comparison content rather than brand-owned pages for most competitors.

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 →
