After doing nothing but whitehat on a site with 3 keywords for about a month (Site was 4 months old)I achieved G ranks, 22,9,8. That is where I hit the wall and didn't move at all. The first keyword is highly competitive or at least getting that way quick, the other are the same way. I just made an investment (or I hope) into it by doing some blackhat seo work. I began yesterday and already all my ranks have dropped out of the top 100 but still indexed. Everyone always says it comes back stronger, do you think with all the whitehat work getting me that far that blackhat will take it to the next level?
