I got a blog which is from 2005.It got changed in 2012 into a blog about forex.There are now over 200 high professional unique articles. When i check webmaster tools i can see that arround 800 keywords are listed on google for my blog. The issue is the blog itself isn't getting much traffic even it has a PR5 and some heavy links from big sites. I'm getting daily arround 50 clicks from google. Checking webmaster tools i saw that my keywords are ranked from 30-120 which means not a single one is on the front page and getting the most possible displays. How would you systemeticly increasing these 800 keywords to get them on the first page without risking any punishment ?
