Indexing

Definition

Indexing is the process by which search engines like Google add web pages to their database (index) after crawling them. Once a page is indexed, it becomes eligible to appear in search results. The process involves: crawling (discovering the page via links or sitemaps), rendering (processing HTML, CSS, and JavaScript to understand the content), and indexing (storing the processed content in Google's index). Not all crawled pages get indexed — Google may skip pages with thin content, duplicate content, noindex directives, or low quality. You can check your indexing status in Google Search Console's Coverage report. To encourage indexing: submit your XML sitemap, ensure good internal linking, create quality content, and avoid noindex tags on important pages.
