At a glance
What we observed in this category
Allied Universal and Securitas share the top position with identical scores across every metric: 37.5% visibility, 12.5% citation, and a composite of 30.0. Both tripled their visibility from 12.5% in the prior period. The category average visibility sits at just 6.7%, meaning these two brands are running at more than five times the average. GardaWorld trails at 25.0% visibility and a composite of 17.5, creating a clear three-brand tier above a long tail of brands scoring zero.
GardaWorld presents the sharpest divergence between visibility and citation in this dataset. It appears in 25.0% of AI responses but carries a 0.0% citation rate, down from a positive citation delta in the prior period when citation dropped by 25.0 points. Sunstates Security inverts this pattern entirely: 0.0% visibility but a 12.5% citation rate, giving it a composite of 3.8. This means Google AI Mode references Sunstates Security as a source without naming it prominently in answers.
Google AI Mode is the dominant engine for every brand in this dataset. The top cited sources in the category are not brand-owned domains but third-party platforms, including reddit.com, indeed.com, youtube.com, and niche sites such as investigativeacademy.com and securitybasegroup.com. Brand domains like aus.com and securitasinc.com are not listed among the top cited sources, which suggests AI responses about this category anchor on community, employment, and directory content rather than official brand pages.

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 →
