If you work in SEO, it can be very useful to know how often the search engines are crawling your website and exactly which pages they're crawling. This is important because if you're suffering from crawling issues, then some of your website might not be being indexed by the search engines. This would mean these pages wouldn't appear in the search results, which would mean fewer website visitors – a situation you obviously want to avoid. Thankfully, there's a way you can check with 100% accuracy how often and which of your webpages are being crawled: log analysis. This video explains why log analysis is so useful for SEO and when it is especially useful to conduct one.
