I had quite over 248 pages indexed by Google. 2 of those pages were ranking almost on the 3rd spot. I noticed that a few days ago my number of indexed pages dropped by 14. Today almost 20. Any ideas why this is happening and why these pages which ranked so high and well are no longer on Google index?
Could this be because I commented on blogs and linked back to my site? Isn't that what Link building is all about?
Thanks for your helpful answers.
