At a glance
What we observed in this categoryauto-generated
Exclaimer leads the email signature software category with a visibility score of 50.0% and a composite score of 61.2, more than 16 points clear of second-placed CodeTwo at 45.0. That gap is significant because the category average visibility sits at just 7.5%, meaning Exclaimer appears in AI responses at roughly 6.7 times the category mean. Exclaimer also rose from rank 4 to rank 1 this period, gaining 12.5 visibility points and a striking 50.0 citation points, reinforcing its accelerating dominance in Google AI Mode.
A notable divergence between visibility and citation exists lower in the rankings. Rocketseed and Bybrand both hold 0.0% visibility yet carry 62.5% citation rates each, matching CodeTwo's citation rate despite CodeTwo having 37.5% visibility. This means Google AI Mode references Rocketseed and Bybrand as sources or context without surfacing them as named answers, a pattern that signals citation without prominence. Brands like Mail-Signatures and Letsignit show the same pattern at lower citation levels, suggesting the AI uses them as corroborating sources rather than primary answers.
Google AI Mode is the top engine for every brand in this dataset, indicating the category's AI visibility is almost entirely concentrated in one engine. The top cited sources list includes exclaimer.com, rocketseed.com, newoldstamp.com, bybrand.io, and codetwo.com alongside third-party domains youtube.com, attrock.com, and anniemargaritayang.com. The presence of those two non-brand editorial and video sources suggests Google AI Mode is anchoring responses partly on review and tutorial content, not solely on vendor sites.

Sources AI engines trust in this category

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.
