Expected Behavior

Search engine crawlers systematically index websites to power search engines by discovering, analyzing, and cataloging web content. They visit sites on dynamic schedules determined by algorithmic priorities rather than fixed intervals. Crawl frequency depends on factors like site popularity, content freshness, update frequency, and domain authority. These crawlers typically respect robots.txt rules and throttle their requests to avoid overwhelming servers.
