At a glance
What we observed in this category
MailStore leads the email archiving software category with a visibility score of 50.0% and a composite score of 61.2, nearly 20 points ahead of second-placed Mimecast at 41.2. The category average visibility sits at just 11.2%, meaning MailStore is running at more than four times the average. This gap is meaningful because it suggests AI responses in this category are heavily concentrated around a single brand, leaving most of the 20 tracked brands with minimal or zero AI presence.
A notable divergence exists between visibility and citation across the top five brands. Google Vault, Smarsh, and ArcTitan all hold 25.0% visibility but record 0.0% citation, meaning AI mentions them without linking to their domains. Intradyn shows the sharpest reversal: 0.0% visibility but 50.0% citation, indicating its domain is being used as a source even when the brand itself is not named in AI responses. These splits suggest being named and being trusted as a source are distinct and separable outcomes.
The top cited sources list shows that AI responses in this category anchor heavily on vendor-owned domains, with mailstore.com and mimecast.com appearing alongside third-party sources including gartner.com, reddit.com, and youtube.com. Titanhq.com and intradyn.com also appear as cited sources despite neither brand ranking in the top three by visibility. All top engines recorded in the data point to Google AI Mode exclusively, confirming this audit reflects a single-engine landscape with no multi-engine distribution visible in the dataset.

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 →
