Hi, For one of my sites, webmaster stats had 9 pages with links now it has 7 pages. Why did google drop two pages even though they still have links pointing to them?
I have seen it happen to one of my blog all the time. Don't worry and keep on building those back links.
You know google update his data- base everyday, so it's normal, and you should keep on get backlinks,and then you can find that more and more page have indexed.
