type in google "yourdomain.com" , if your site not on first position may be google penalized your site.
Thnx for ur reply. But sume1 told me that if ur site's cache is not done between 5-6 days than its mean that site is penalize by Google. Is it true ?
It is 100% wrong. Google takes some time to update. You can update something in those posts and then you will see that google have indexed. For blogs, every time a comment is posted, it is indexed that many times.
