The amount of time and resources that Google devotes to crawling a site is called the site's crawl budget. A crawl budget is critical for SEO as it affects how search engines find and index your site's pages. It depends on two things: crawl limit and crawl demand. search engine bots are also known as crawlers or spiders. When a crawler visits a web page, it reads an HTML code and extracts other elements such as text, images, links, and metadata. The crawler then processes the extracted data and stores relevant information about the page in the search engine's INDEX. This index is a massive database containing information about all the web pages the search engine has discovered. Once indexed, the search engine algorithms determine the relevance and quality of each indexed page based on a lot of factors. This information is then used to RANK the pages in search results when a user enters a search query.
