SERP features are search result elements such as snippets, People Also Ask, local packs, images, videos, and AI modules.
SERP features affect visibility. They can push organic links down, answer the query directly, or create new citation surfaces.
Feature tracking is most useful beside normal position data, so teams can explain traffic changes without guessing.
Use bisibility when you want classic Google rank checks, BYO provider credentials, owned Postgres history, API access, and agent-readable discovery surfaces.
