My position in the serp of google is 90, i have the best website in the niche, with a lot of articles, my seo onpage is good... or at least it say IBP... I have a lot of back links...1800... My website is 5 month old... do you think it can be the problem? Maybe the problem is that the blacklinks are from english websites and my web is in spanish? should i buy some quality backlinks with pagerank 5 or 6?????
