Search engines typically start crawling websites from a list of URLs known as a "seed list." This list is compiled by the search engine's algorithm and typically includes popular or authoritative websites in a particular topic or industry.
The search engine's crawler, also known as a spider or bot, will begin by visiting the URLs on the seed list and then follow any links on those pages to discover and crawl new pages. The crawler will also revisit previously crawled pages to look for updates or changes.
Search engines use complex algorithms to determine the relevance and importance of a website, based on various factors such as content quality, inbound links, user engagement, and more. As the crawler indexes more pages and gathers more data, the search engine's algorithm will continually adjust and refine its rankings to provide the most relevant and useful results for its users.

To summarize, search engines start crawling from a seed list of URLs, usually consisting of popular or authoritative websites. They follow links on those pages to discover and crawl new pages, and they also revisit previously crawled pages for updates. The search engine's algorithm then determines the relevance and importance of a website based on various factors, and continually adjusts its rankings to provide the best search results.
