A friend of mine is paying $100 a year for hosting. Since his niche is relatively small (maximum 100 views per month) I've suggested changing host to 000webhost to save those $100 or changing host to someone cheaper. He is afraid that by changing host his website will get de-indexed and will need to rank all over again. I told him that I believe this will not be the case but thought of asking just in case (Just in case the same thing holds where people buy high PR domains and google decides to take the PR away because the owner changed). What do you think?
