I have never promoted them, but generally, you need to get the offers that your visitors are interested in. So for example, on a MILF site, you do not want to promote teen dating products, it will not sell at all. It is a good idea to research on Google for related sites in your niche and see what they do, you can learn from this a lot.

A blog can be about anything you want and the best thing is that it can be very simple. Here is an example of a good blog: blog.mrpinks.com.

Are you going to produce the content, buy it yourself or you are going to just download and share it on your site? I would avoid doing the latter because not only it is illegal, but also this way you will not make much money, because people can watch full movies on your site so why should they sign up for other site and spend cash?

It looks like your site is down at the time I was reading your topic. Generally, if you are looking for affiliate programs then search on Google for this kind of query: nude girl affiliate program or milf adult affiliate programs, you get the idea. I can also tell you that the MetArt is a very good sponsor and they should sell well, at least it is what I have heard from other webmasters.
