making money with porn site

Porn is a hard nut to crack...
PS. What do you mean by "List videos from other sites?"...

This is not a good idea.
There are a lot of options that will be more beneficial for you.

It may sounds easy but just remember this is a niche has over optimized. To break in you better need hell of an advertising budget and SEO strategy in place. It is technically not worth it for new players as you can break through other niches easier with less cost

This idea may blow but let's see...

You have the right idea. What I would do is find videos from one source and embed them on your website. You'll send traffic to this video site of yours for a month. Once you get 500 to 1,000 views per day without spending money on traffic then, sites like this tend to self perpetuate. Just make sure you tag them with there proper categories, this is critically important.

You'll want to make sure that you have a news letter set up for these individual categories, according to your stats you will put that opt in for on that specific page because some people who watch specific videos really love only that type of video so they will opt in to get them delivered directly to their email.

Now you have two sources that you can use as income streams.

1. As the visitors come to your site you can sell traffic to advertisers who are trying to sell their products, services and games.

2. As your email list grows, you can send advertisements directly to their email that links out to the actual product or services.

I'm sure there are more ways you can draw income from this site.
