All right, so I've been building niche sites for a long time now, almost a year, and I've never ran into this problem. I need some opinions and advice from those of you who have also experienced this same issue. I'll get into the details below: I've gotten really good at SEO and analyzing the 1st page of Google for a certain keyword phrase to see if I can rank on it or not. I setup niche sites with exact match domains and proper on-page SEO and they ALWAYS get indexed on one of the first 3 pages, usually page 1 or 2. They will fluctuate for a little while due to the Google Dance, but they always come back and then some normal off-page SEO gets them to page 1. I have done this countless times without fail, but over a week ago, I ran into a problem which I feel is the "Sandbox" and I need to know how to get out of it if I can. I bought 6 new exact match domains and built 6 WP blogs on them using the same strategies I always do. All the proper on-page SEO was done (keyword in title, meta tags, description, etc.), and the first page competition is weak. I know that even a brand new site should be ranking somewhere on pages 1-2 due to the exact match domain and on-page SEO. Anyway, all 6 of those sites are indexed according to Google, but they are not showing up anywhere in even the first 10 pages for my keyword phrase when normally my sites always index high up if I did good keyword research. Normally I wouldn't be concerned if it was just a site or two, but since all 6 of them are nowhere to be found, and they are indexed, it's a bit suspicious to me. I know the first thing most of you will ask is about the competition, but I can assure you it's very weak as I did all the research before selecting these keywords. My only guess is that I got all 6 of these sites sandboxed for some reason, but I'm not sure why. I haven't done any aggressive linkbuilding or even added Adsense yet so they can't think they are MFA sites. Do you think maybe Google is catching onto me and see that almost every site under my IP is a niche site so they are just not ranking the new ones I build? I don't know of any other reasons. So those of you that have experienced this, what do you think it is and what's the solution here? Thanks for the help.
