What is Crawling?
Crawling is the first step search engines take to discover and analyze web pages. Crawlers (also called spiders or bots) like Googlebot visit websites, follow links, and download page content. The collected data is then indexed and made available for search. Crawl frequency depends on various factors: website authority, update frequency, server speed, and internal linking. Webmasters can control crawling via the robots.txt file - certain areas can be excluded from crawling. The XML sitemap helps crawlers find all important pages. Crawl budget is an important factor for large websites.
