seo Information

The Total Index - To find out how many of your pages are present in Google's Total Index, search the following on Google:   site:yourdomainname.com

In the smaller text below the search box, and above the search results, Google will report the number of pages in the Total Index (primary plus supplemental). You should know how many total pages are in your site. If the number of pages in Google's total index is substantially lower than the total number of pages in your site… you have some work to do.

The Primary Index - To find out how many pages are in the primary index, search the following on Google: site:yourdomainname.com/*         The number of pages reported are the number of pages in the primary index. Google considers these to be the best candidates in your site for ranking on popular phrases.   If the ratio of pages in the primary index to pages in the total index is under 10%, then you have a serious problem. Ideally with some good work, you can get the ratio north of 30% or even 40%.

The Supplemental Index - To find the number of pages in the supplemental index, simply subtract the number of pages in the Primary Index, from the number of pages in the Total Index.
