A crawler shouldn’t attempt to crawl pages that change frequently. Crawlers shouldn’t visit pages that have changed less often than the average website freshness and age. He should then stop the crawler visiting the site again.

This strategy works well for large collections of links. It allows crawlers discover new backlinks, and other types. Its main benefit is the ability of indexing web pages without worrying about security.
