My site has 40,500 pages indexed in google, but not all pages are cached in a regular interval although it is doing well in google, yahoo and msn. What is the reason for difference in caching dates of my site.
Please anyone help me.
Thanks for your support.
But I have one more question to you. Will the http://example.com and http://www.example.com have different SERPs effect as you say that these are treated as different domains? And also that is there any bad effect of using htaccess file?
