Website Crawlers tools are computer programs that perform scanning of the web. They read everything on the web. To be precise, they crawl the entire website following internal links which enable them to understand the structure of the website and the information present on the website. The scanning is performed to understand the content and topic on the webpage.
The
crawler stores the findings in an index which can be termed the largest library
across the globe. This information is utilized based on what the user is
looking for. When you ask the search engine about a certain topic, the engine
checks the index and offers a list of web pages that it finds relevant. The web crawler tool scans the web regularly so
that it can update the index.
