One of the many sites I have is http://best4digitalcameras.com which has reviews of cameras.

It was doing quite poorly with adsense on the site. So I took those out and focused exclusively on affiliate links, as all the products on there are from Tigerdirect. Although there are only 20 something posts, it managed to make $47 for the first 3 weeks of January. And I haven’t updated anything for three months. The commission double after $50, so if it goes over $50, it goes straight to $100.

http://computer-reviews.net doesn’t make this much in a month, but has over 350 posts, although not updated for a very long time.

I stronly suspect that the digital camera site is just a market with more regular buyers, as opposed to the computer market. I also suspect that the keyword list I used for creating the most recent posts on the digital camera site helped a lot. Computer reviews also had a great run in the first few months when I was focusing on keywords with high Wordtracker KEIs.

I will need keyword research for starting the Google adwords campaign later, but the wordtracker subscription is expensive at $329 per year, but so worth it. The monthly option is $59 per month, which is steep. Might just prepare what I need to search for and then sign up for one month as it doesn’t need to be recurring.
