Why the google deletes my pages ?

Why the google deletes my pages from an index, was 650 now 265 ?

 

Not delete, Just discard the pages of no importance. It's their algorithm, nothing can be done, just optimize your pages and gain links in support to them.

 

Thanks for reply. I wil try....

 

you didn't specified your page

 

Yes, sometimes pages get dropped for no reason, and you never know why. Ah, Google...

 

we need to call to Sergey Brin and ask about it
P.S My site is internet store, it is very bad for us.

 

try to get quality back links.... avoid LE with no quality sites... 3 way is example

 

Just get good numbers of backlinks.

 

there is a set of formula they follow for indexing n nobody knows.. the index decreases as google crawls and finds details about the website.. removes duplicate and also spammed links to the original site..
