Crawling in SEO refers to the process by which search engine robots, also known as “spiders” or “crawlers,” scan and index the pages of a website. The purpose of crawling is to discover new pages and to update existing pages in the search engine’s index so that they can be displayed in the search engine results pages (SERPs) when relevant to a user’s query.
When a search engine’s crawler visits a website, it starts by following links on the website’s home page and then continues to follow links on subsequent pages, discovering and indexing new content along the way. The crawler stores information about the website’s content, structure, and other elements in its index, which is used to generate the search results.
Crawling is an important aspect of SEO because it allows search engines to understand the structure and content of a website and determine its relevance and quality. By improving a website’s crawl ability, website owners and digital marketers can help ensure that their website is properly indexed by search engines and appears in the SERPs for relevant keywords and phrases.
Overall, crawling is a crucial part of the search engine optimization process and plays a key role in determining the visibility and ranking of a website in search results.
