some days back my website lets say ABC shows 2345 number of searches in google ... But today it just get down and showing 1024 number of pages in google search .. Can anybody tell me what could be the reason ?
It's called Google and this happens quite a bit. At least I see it a lot. Sometimes you will get different returns just by refreshing the page.
Another good reason might be you got results from different data centers, which usually are not synchronized with their contents and results.
