What is Crawling in SEO?
Search engine spiders crawl the web to find and index new pages. The crawlers can only find new pages through links from other sites, so they must know where to go to get there. The crawling process also involves preparing data for indexing. Website owners can submit sitemaps to have their pages crawled by Google. Managed web hosts will also submit your pages for crawling. In some cases, crawling is optional.
Web crawlers require resources from the server to index content. They make requests to the server, which must respond to those requests. Some website operators do not want too much indexing as it can overwhelm the server and increase bandwidth costs. So, make sure you understand the difference between crawling and indexing.

Search engines use a crawler to find new information and make decisions. It starts with a handful of trusted sites, which serve as a base to evaluate other websites. It then expands its crawl across the entire web by following links that visitors clicked on. To get more information about crawling, you can perform an SEO audit. A crawler also helps the search engine determine the relevance of a web page and helps find relevant information for users.
The crawler is an automatic navigator, also known as a “bot” or a “spider”. Google sends out these robots constantly, and they crawl web pages to find relevant content. The crawler loads these URLs in a queue, and visits them at a later time. When a new page is published, a crawler will add it to its Caffeine index, which is a massive database of discovered URLs.
Crawlers operate on search engines and add information to their index. Search engines use this index to generate relevant links for users. When a user searches for a certain topic, the bots pull information from the index to create a list of relevant websites. Googlebot is one of these robots. It also uses sitemaps submitted by website owners. It does this job on behalf of Google. Its mission is to collect as much information as possible from the web.
Crawlers can encounter errors while accessing URLs. Occasionally, they encounter errors, such as 5xx errors. These errors indicate server errors or not-found errors. To resolve these problems, check Google Search Console’s Crawl Errors report. You can also check server log files to see how often a spider crawls a page. The server log files can provide useful information on crawl rate and budget.
