Indexing Problem In Google Serps Pages are being dropped from Google index...

[iGuest 3]

I took few hours to read this long post from Google Engineer Matt Cutt in his blog https://www.mattcutts.com/blog/indexing-timeline/ entitled "Indexing timeline" posted on 16 May,2006. It covers burning issues like why the pages of many websites are constantly being dropped from Google index with particular reference to link-exchange programs and Google's famous IBLs.
It also depicts in a nut-shell the changes in Google index that took place since the inception of BigDaddy. It appears that the big "G" is going to fire out websites participating in Link Exchange programs and contain irrelevant links.
The best part of this long post by Matt is that he has mentioned specific "example" sites to show why pages from those sites are being dropped constantly. The selection of example site is absolutely splendid and covers a broad spectrum.
There are a large number of thought provoking comments as well. Please spend some time to read that post by Matt, it is really helpful.
