I bought an expired domain some weeks ago, the domain had the same niche which i am building now. I added 5 articles (for every kw i target 1 article). But i am not ranked in top 200 for any kw, is it normal? I can remember when i used a brand new domain, added some articles i was already ranking for long tails and some of my target kws, but in this domain nothing! So is it bad to use expired domain as money site?
