Frequently Asked Questions
Why do AI answers change over time?
AI answers are rebuilt from live retrieval and evolving models, so they drift as pages update, reviews accumulate, competitors optimize and indexes refresh. A brand can be named one month and gone the next - which is why monthly answer snapshots are worth keeping.
How do I use this diff checker?
When you run your monthly AI visibility checks, copy the answer text into a note. Next month, paste the earlier answer and the fresh one here: the tool highlights every removed and added word and specifically flags whether your brand name appeared, disappeared or survived.
My brand was removed from the answer - what now?
Treat it as an early warning, not a verdict: re-check the basics (crawler access, consistency, review velocity, content freshness) because a regression there is the usual cause. The free DigiMSM AI Visibility Audit traces exactly which layer slipped.
