I recently got a penalty for my site which is for my local offline business. It is not that competitive but I dont want to be hit again and have down time as it is really affecting my business. My plan is to get top 5 with 3 different sites all going for the same keywords. Can I get penalty/sandboxed if G sees that Im trying to do this? It would also serve as split testing to see which site performs the best. Any precautions I should take. OR is it all good?
