AI search trackers
Each AI engine picks sources and brands differently. Here is how the six engines Yozigo tracks compare, and a tracker page for each.
How do the six AI engines compare?
We compared every answer Yozigo recorded on each engine from 4–10 October 2026: 37,176 answers in total. ChatGPT reads the most sources, Perplexity names the most brands, and Google AI Overviews gives the shortest answers with the fewest brands. Google AI Mode and Copilot figures come from a smaller sample of two brands.

Which engine should you track?
Track the engines your buyers use. ChatGPT, Perplexity, Gemini and Google AI Overviews cover most people and are included on every Yozigo plan. Add Google AI Mode for Google-heavy markets and Copilot for B2B buyers who work in Microsoft 365; both are on Momentum, Authority and Enterprise. Because each engine names different brands, being visible on one says little about the others.
