Steve over at Ramblings from the Marginalized recently sent me this question.
I’ve noticed your AdSense revenue has been looking very good as of late. I’ve also noticed a lot of the same ads showing up on your site.
Is this because you are getting more people paying for CPM ads on your site?
I’m just curious what percentage of your AdSense comes from CPC as opposed to people paying for impression based ads.
To find out the answer I need to log into my Google AdSense account. Many webmasters don’t know this but the Google stats can show the breakdown between normal contextual ads and SiteMatch ads. For those how don’t know, Google SiteMatch ads are CPM ads purchased directly to the site instead of having Google select the sites for you based on keywords. How do you know if there are any SiteMatch ads running on your blog?
Go To Advanced Reports
In your Advanced Reports AdSense stats, you’ll see a drop down menu that say “Show data by.” By default, it’s set to show data by page. Change this to Individual Ad. A check box will appear that reads, “Show data by targeting type – contextual or site.” Make sure that box is checked. Then select the channels you want stats for and hit display report. You will get something like this.
The blog served 554,708 Google 300×250 ads last month. Of those, 110,945 were SiteMatch ads. However, the SiteMatch ads accounted for $344.06 of the $1,077.63 ad income. In other words, SiteMatch ads were 20% of the inventory but accounted for 32% of the income. Are you getting any SiteMatch ads on your blog? If so, how much of the total AdSense income do they account for?
If you wish to buy a SiteMatch Google ad on this blog, you can do so here. Remember to bid high or your ad may not show up.

One of the most common complaint (or excuse) I hear from potential new bloggers is they don’t know how to install WordPress. Terms like FTP and CPanel are like a foreign language and setting up a database might as well be setting up the space shuttle for a launch. Because of the technology barrier, many would-be bloggers never start their blogs...
