Indexability
Indexability means how able a page or site is to be indexed by search engines. After bots crawl your site, they decide if each page gets stored in search results. This is a go or no-go choice where pages either get indexed or stay out of search results.
Search engines store pages in a vector database with thousands of dimensions to give each page an address. This is how they handle relevance. They save key data like URL, title, description, and ranking metadata for instant recall. Your Site Structure helps bots find pages while crawling. The Sitemap gives search engines a list of all URLs that exist on your site.
Poor indexability happens when Robots.txt blocks pages, Nofollow/Dofollow links prevent discovery, or pages become orphaned without Internal Links. Technical SEO fixes these issues to improve indexing chances. When people search on Google, they search the index for results based on Anchors, Body Content, and Clicks data that Google stores for each indexed page.
