the keywords i want to rank high with are Browse at work does my site have enough of those keywords to have the potential to be ranked high?
There are several ways to check: - Compare with your competitors. - I can see that you are using adsense. If it display the correct ads (ads that have the keywords you want to target) then you are doing fine. In the end, having the correct number of keywords won't guarantee you a high position if it's competitive enough. If so, everybody could do that. You need to rely on more backlinks than keywords density.
