What is Algorithm Update?
Definition
A change to Google's ranking systems. Major named updates (Core Updates, Helpful Content, Spam updates) are announced; smaller changes happen daily.
Why it Matters for AI Search
Tracking algorithm updates helps diagnose ranking changes. If your traffic dropped on a specific date, check whether it aligns with a known update — that tells you whether the cause is algorithmic, technical, or content-related.
