A SERP is the search engine results page returned for a query, including links, ads, features, maps, and AI modules.
SERPs are no longer just ten blue links. They can include snippets, People Also Ask, local packs, products, videos, and AI answers.
A visibility tool should keep enough SERP context to explain why a ranking changed.
Use bisibility when you want classic Google rank checks, BYO provider credentials, owned Postgres history, API access, and agent-readable discovery surfaces.
