I'm currently using Adsense only for content, but also want to use the "Custom Search" for Adsense option. I've set it so that the search results will open in a page of my blog because that gives me a lot of freedom in terms of design. I could also place some of my Adsense ads around the search results. However, I'm not sure if that's allowed. Usually we're allowed 3 ad-units per page and I can't control how many ads the Google Search is displaying. So, can I put some Adsense ad-units on the Google Custom Search page or not?
Besides the 3 ad units , you are also allowed to put Google custom search page. It is allowed and i am also using this in my blogs.
