This indicates a strong recognition for Orb in the field, making it a prominent name when considering solutions in this category.
The rankings reflect the sources AI engines pull information from most frequently. Leading mentions come from withorb.com, blog.alguna.com, and billingplatform.com among others.

At a glance
What we observed in this category
Orb leads the usage-based billing software category with a composite score of 40.0, well ahead of second-placed Lago at 35.0 and third-placed BillingPlatform at 27.5. The category average visibility sits at just 6.2%, making Orb's 25.0% visibility and 75.0% citation rate a significant outlier. Orb also rose four rank positions from its previous standing, meaning the gap at the top is both large and widening, which concentrates AI-driven discovery risk for all competing brands.
The most striking divergence between visibility and citation appears at ranks 4 and 5. Subscript holds 37.5% visibility (the highest of any brand in the data) yet carries a 0.0% citation rate, and Metronome mirrors this with 25.0% visibility and 0.0% citations. By contrast, Maxio has zero visibility but a 50.0% citation rate, and Lago combines only 12.5% visibility with an 87.5% citation rate. Being named in AI responses and being trusted as a cited source are clearly distinct outcomes in this category.
Google AI Mode is the top engine for every brand in the dataset without exception, confirming that this category's AI visibility landscape is currently a single-engine story. The top cited sources list includes withorb.com and getlago.com alongside third-party domains such as blog.alguna.com, ledgerup.ai, solvimon.com, and hyperline.co, suggesting the AI anchors on specialist niche publishers and competitor-adjacent content rather than large general-purpose review platforms.

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 →
