I've had a site for the past 2-3 years that now has 30 or so articles, it ranks top 10 for a number of mid-low traffic keywords; but I seem to have run out of keywords to target for articles.
The top 3 keywords, I am ranking as:
1 - #9 (40,000 EXACT searches)
2 - #7 (21,000 EXACT searches)
4 - #5 (9,900 EXACT searches)
It's receiving 150-200 UV a day, achieving minimal Adsense earnings; what do I do at this point?
