At a glance
What we observed in this category
Equinix leads the colocation category with a composite score of 55.0, well ahead of Digital Realty at 43.8 and QTS at 26.2. The gap between first and third place is substantial enough to suggest Equinix is treated as a default reference point by Google AI Mode. Both Equinix and Digital Realty share identical visibility scores of 62.5 percent, yet Equinix's citation rate of 37.5 percent versus Digital Realty's 0.0 percent is where the real separation emerges, making Equinix the only top-two brand that is both named and trusted as a source.
Several brands show a clear divergence between being named in AI responses and being cited as a source. CoreSite has zero visibility but a 50.0 percent citation rate, the highest citation figure in the dataset. Iron Mountain Data Centers similarly holds a 37.5 percent citation rate with zero visibility. DataBank and TierPoint each carry 25.0 percent citation rates against only 12.5 percent visibility. This pattern suggests Google AI Mode draws on these brands as reference material without surfacing them as recommended providers in generated answers.
Google AI Mode is the top engine for every brand in this dataset without exception, confirming the audit is effectively a single-engine snapshot. The top cited external sources include datacentremagazine.com, gartner.com, encoradvisors.com, and reddit.com, alongside brand-owned domains ironmountain.com and coresite.com. The presence of coresite.com and ironmountain.com as cited sources aligns directly with those brands' high citation rates despite low or zero visibility, indicating the AI is pulling structured or authoritative content from their own 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 30 days and refresh this page automatically. How AI search ranking works →
