The server log file records every single hit on the site. Doing research on the log file allows you to find out which pages are being crawled by the bots/crawlers and you will also be able to find out which pages the bot has problem crawling. Besides, it also let you know how visitors arrive on your site for example by organic search queries or a referral site.
