Having mainly focused on affiliate marketing, I want to seriously try my hand at adsense with a domain I bought a while back and haven't done much with yet. I've found a bunch of related low comp longtail keywords to use. Although their search volume is low, the comp is also low, and the CPC is in the $3-$6 range. I plan on writing a lot posts, focusing on one keyword per post.
Here's my question. What's the best way to get the ads to reflect the longtail keyword without engaging in keyword stuffing? I'm assuming the post title should be the longtail keyword, but is there a density to shoot for in the content to get the right ads?
I'm looking for advice from anyone with successful experience.
