At a glance
What we observed in this category
Dropbox Fax leads the online fax services category with a composite score of 41.2, more than 10 points clear of second-placed iFax at 31.2, and nearly 13 points ahead of FAX.PLUS at 28.8. That gap is significant because the category average visibility sits at just 5.0 percent, meaning Dropbox Fax's 37.5 percent visibility represents a dominant outlier position. Dropbox Fax also rose from rank 4 to rank 1, adding 12.5 visibility points and 25 citation points in the most recent period, signalling accelerating momentum rather than a static lead.
iFax presents the sharpest divergence between visibility and citation in the dataset. Its visibility of 12.5 percent sits at the category average tier, yet its citation rate of 75.0 percent is the highest of any brand, including the overall leader. RingCentral Fax shows the inverse pattern: zero visibility but a 50.0 percent citation rate, matching Dropbox Fax on citations despite never appearing as a named brand in responses. This split suggests AI systems are referencing these brands as trusted supporting sources without actively featuring them as primary answers.
Every brand in the top 10 lists Google AI Mode as its top engine, confirming that this category's AI visibility landscape is entirely shaped by a single engine. The top cited sources list includes ifaxapp.com, fax.dropbox.com, ringcentral.com, and pcmag.com alongside emitrr.com and iplum.com, indicating the AI is anchoring on a mix of brand-owned domains and third-party review or comparison content. The presence of pcmag.com and emitrr.com in cited sources suggests editorial roundups are a meaningful input into how Google AI Mode constructs its responses 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

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 →
