Search engines help users locate information on the web. They crawl websites to index their content, then serve search results based on relevance algorithms like PageRank. Search engine optimization (SEO) aims to improve a website's visibility in search results through on-page techniques like optimizing titles, meta tags, and keywords as well as off-page techniques like getting links from other popular websites. It is important for SEO that search engines can properly crawl and index a website.
