“Crawl Budget” refers to the amount of resources that search engines allocate to crawling and indexing a website. It includes factors such as the number of URLs that a search engine will crawl per day, the time spent on each page, and the frequency with which a site is crawled.
A website’s crawl budget is limited, meaning that search engines will only crawl a certain number of pages from a site in a given time frame. As a result, it is important for website owners to optimize their sites for search engine crawlers in order to ensure that their most important pages are crawled and indexed.
This can be done by reducing the number of low-quality pages on a site, fixing broken links, improving page load times, and using sitemaps and robots.txt files, among other strategies.
