Site index not updated

My Google Site index is not upated for the last 1 month or so. Google bot visits my site regularly but it is not updating. What could be the problem?
Does anybody has solution for this problem?

Thanks

 

I have the same problem

 

Just like PR and link:site, these indexes are exported at (seemingly) irregular intervals. I've seen pages indexed in less than a week, or longer than two months.

 

just because a BOT visits - it doesn't mean it is indexing necesarily. The Big G has many BOTs doing many things.

Generally the indexation of the is based on a handfull of factors including backlinks, freshness,site age, authority and so on..... some sites get a new cache of a page every 2 weeks... some ..every day. It will vary from site to site.

There is also the issue of datacenters - while everflux is the norm and dta refreshes are constant - some DCs can show different results from time to time.....

In the end... keep on link building... always increases indexation.

 

The real truth is that GoogleBot each time indexes all the pages and stores at different datacenters ,

I have seen some datacenters displaying different no of indexed pages for my site!

 

Freewebspace is true.

googlebot visits your site different ips if you take care. you must check the index of google datacenter
