CTR Theme Plus (for WordPress) makes it easy to build informational websites monetized with AdSense that get awesome click-through rates (CTR). AdSense provides hands-off recurring income, but usually these sites leave a lot of money on the table by having bad designs or underoptimized ad placement.
The idea behind CTR Theme Plus is to make it dead easy for you to build an army of high-earning AdSense sites. If we charged a fee for each installation, that would kind of defeat the purpose, right? Install it on as many domains as you want. You also get access to Support and Theme Upgrades for one year from the date of purchase.
