Even though there are lots of spots to place codes, I would recommend you to limit the ads to a reasonable number. Otherwise, search engines will punish your site as made for ads or popularly called as Made For Adsense (MFA).

I tested the theme with one of my hobby site with three ad spots. I placed one ad on the left side bar and two others inside the content area which randomly rotates for each post. However, I am yet to see any earnings.

You should not expect to make any earnings from the day you installed the theme if your site is new. It takes time for the search engines to list the site and become popular.

From my point of view, CTR theme may not be suitable for fresh sites unless the site brings traffic directly from search engines like Google, Yahoo and Bing, which of course will take time. You will be required to work hard to create quality and site specific backlinks to get any returns from the theme.

I would recommend the theme for established niche sites with unique content if the webmaster agrees to compromise on the site design. You should test the theme on a site which is already earning revenues from ad services.

The theme also includes a separate document which examines several link building techniques. I hope the tips provided by the developer will help beginners a lot. The developer also provides free updates as and when they are released and a license for unlimited domains.
