Every brand is scored 0–100 on eight signals — citation, trust, entity strength, coverage, source diversity, consistency, freshness, and expert mentions — measured from real answers given by AI engines to real buyer questions. The ranking is the score order, with no paid placement.
Is Customer.io still worth using in 2026?+
Customer.io ranks #3 of 3 tracked Marketing Automation Tools brands with a Signal Score of 76/100, which puts it among the most AI-visible options in its category.
Why does AI visibility matter when choosing an alternative?+
Buyers increasingly ask ChatGPT, Gemini, Claude, and Perplexity for recommendations instead of scrolling search results. A brand that AI engines never name is invisible at the moment a decision forms — so how a tool is represented in AI answers is now part of how easy it is to evaluate, adopt, and get support for.
