    Crawling is the process search engines discover updated content on the web, such as new sites or pages, changes to existing sites, and dead links.
    To do this, a search engine uses an algorithm that can be referred to as a 'crawler', ‘bot’ or ‘spider’ which follows an algorithmic process to determine which sites to crawl and how often. As a search engine's crawler moves through your site it will also detect and record any links it finds on these pages and add them to a list that will be crawled later.
    This is how new content is discovered.
