Web crawlers, like Googlebot, follow links from one page to another, gathering content and storing it for indexing. The efficiency of a web crawler is critical for SEO, as it determines how quickly and thoroughly a search engine can index a site’s content. Various factors, including site structure and loading speed, can affect how effectively a web crawler operates.
