Which Google Search Works Best?

I have only tried the custom search type where you put the search bar into your site. I'm wondering about the other search, the one where you set up a custom search engine, the whole page being a search page. Has anyone had success with it? Hardly anyone uses my google custom search , and when the do they never click the ads. I'm thinking of ditching it and just putting in another search.

 

What are you trying to achieve by having the search bar in your site?

 

Having people use it to search and occasionally get a click on an advertiser, isn't' that the reason to use it?

 

I don't really understand, all searches are custom?

 

Sorry if i did not make myself clear, some are integrated into a site, via a search bar field and some are dedicated search engines, like a whole page for searching, that kind of thing.
