I have new authority site, with articles that ate targeting low competition long tail keywords. Site Structure Example: Socialmedia.com Categories 1.Facebook Articles: Top 10 Facebook pages, How to build facebook fan page…. 2.Twitter Articles: Twitter Tips for Beginners, Twitter for Business… 3.Pinterest Atricles: Pinterest Marketing Tips and tricks, Pinterest marketing tools…. The Homepage is not static, so I am not trying to rank Categories (I am not even indexing them) as it may cause duplicate content…and the keywords are med-high competition. My goal is to rank the Homepage and the Articles. My Stats (according to google webmaster) The main keywords are med-high competition and I am not ranked for them. However, I am ranked in the 1st 100 positions for many long tail keywords. Some of them are in the first 30 results with 0 backlinks. Details related the homepage Should I be focused on ranking the homepage, or maybe I should focus on internal pages? Maybe I am making mistake by not indexing the categories? Also, it is not clear to me how to build link building strategy for the inner pages. Example, what if I build more than 100 inner pages (articles). In that case doing seo for each article is impossible as it will cost a lot of money. Any suggestions.
