No. of Index Pages - Huge differences - Google/Yahoo/MSN

One of website I'm analyzing has huge differences for no. of indexed pages.
It is about 1:4:3 (Google:Yahoo:MSN)

I'm aware that sitemap is not good for this website and fixing it for Google.

What could be the other possibilities for such huge difference?

 

looks like mine is 66:16:1

 

any thoughts on it?

 

It could be a vast number of reasons. They all index at different rates and with different algorithms. They are each their own beast. So, they will each view your site differently. It is very typical to have drastic differences in the number of indexed pages in the major search engines. Not much you can do except follow the golden rules for each and hope for the best possible results.

 

And the golden rule would be?

 

Blogs seem to be able to hold more pages than regular sites at times but as far as why there is such a major difference who knows? I think Live counts images as "pages" in some cases which throws our count way off.

 

different search engines value different sites differently so while google might index one site, msn will not. So it all depends...

 

For my sites, MSN index almost all pages where Google is only indexing 30% of total pages

 

Mine is like:

156:181:125

I need those pages, which need to get indexed, so i can get better results,

And that's i am having in G.

No worries, with the difference.
