Crawler

A crawler, also known as a spider or bot, is a program used by search engines to scan and index websites. It works by following links on web pages and collecting information about the content and structure of each page. This information is then used to create a searchable index of the web, which allows users to find relevant results when they search for specific keywords or phrases. Crawler technology is essential for search engine optimization (seo), as it helps search engines understand the content and relevance of a website’s pages. By optimizing your website for crawlers, you can improve your search engine rankings and drive more traffic to your site.
