I have a website www.xyz.com which is basically informational site.
PR of this website is 4.
i have another website with subdomain store.xyz.com, which is actually my online store.
The home page of my subdomin is only PR 2 webpage.
When i use google webmasters tool to check the google crawler frequency, i found that the googlebot visits store.xyz.com every 3-4 days, but only crawls 50-60 pages and leaves.
also it keeps visiting the same pages every time. there are some pages that haven't been crawled for last 3 months and there are some pages that have been crawled every 3-4 days.
note: All pages are very well reachable by human as well as by crawler.
can anybody help me knowing googlebot's behaviour.
