Can log monitoring make a difference for my site?
Logs are the only way to get detailed and complete information about Googlebot behavior. Consequently, almost all websites can benefit from seeing what pages are known (or unknown!) to search engines. Additionally, monitoring crawl frequency also indicates the importance given to a page and how fast it will be updated.
However, for very large sites and websites with frequent content changes such as online media, Googlebot monitoring is essential. These sites are much more sensitive to issues with crawl budget and rely on getting new pages indexed as quickly as possible. For these sites, knowing their crawl rate for different page types is essential to spotting and solving search visibility issues with a technical cause.
