Search engines crawl websites to discover content and store it in databases — a process known as indexation. Once content has been indexed, it can be served up on search engine results pages (SERPs) for relevant search queries. Site audits are an essential tool to evaluate how easily a search engine can discover, crawl, and index everything from individual elements of a webpage all the way up to an entire domain.
