What is crawling in SEO?

This term is broad, and can also be used when referring to crawl “budget”, crawl “depth”, crawl “error” and more. Essentially, it all comes down to the processing of a particular URL. Crawling happens when a website is searched (crawled) by a bot/s. These bots analyze the code and content on a specific page, and gather information about the intent of your content. Crawlers (or bots) will also view internal and external links during the collection process, and index these pages.

While Google allocates crawl budgets to every URL, the amount you get is determined by a handful of things: the importance of a webpage according to its trust signals, the page’s link structure, etc.
