Crawl budget is the amount of resources Google is willing to spend crawling your website. It could be said that your crawl budget equals the number of pages crawled per day, but it’s not exactly true. Some pages drain more resources than others, so the number of crawled pages can vary even though the budget remains the same.

When allocating the crawl budget, Google will generally look at four things: your website’s popularity, update rate, number of pages, and the capacity to handle crawling. But even though it’s a sophisticated algorithm, there is still room for you to interfere and help Google manage the way it crawls your website.
