I have a website but the revenue of google ads is zero what kind of content should i put?

The only way to make money online is to work at it like you would anything else. First find something that people are interested in. One of the best ways to make money is to write. Then advertise your site (spend some money). If people are interested they'll keep coming back. Try to come up with a slick design. If you have the money, or can go somewhere to access dreamweaver, dreamweaver templates are some of the best in the business. I would advise blogging.
