crawl budget refers to the number of webpages search engine crawlers like Googlebot are willing to crawl and index on a website within a given time frame. it is determined based on factors such as website size, Server performance, and crawl demand. Websites with a large number of pages or frequent content updates may have a higher crawl budget allocation from search engines. However, crawl budget limitations can arise If a website has low-quality or low-value content, excessive URL parameters, or inefficient internal linking structures that hinder effective crawling and indexing. If a website exceeds its crawl budget or has crawl budget limitations, search engines may not index all of its content, leading to indexing issues and reduced visibility in search results. webmasters can improve crawl efficiency by optimizing website performance, removing low-value pages, and enhancing internal linking.
