I must see that question on different message boards at least a couple times a day. The obvious reason it's asked is because the person asking is looking for short cuts to riches and forgets one simple thing. Any webmaster that has found a good niche doesn't want to tell anyone about it, because if he does, it won't be a good niche for long. Why? Because a good niche is one that not every webmaster on the planet is promoting.

What I'm about to say is a generalization because even saturated niches like 'teens', are good niches for the webmasters that have been promoting that niche for a while and have built up a solid traffic base. However, for a newbie, the obvious -- and thus popular -- niches like 'teens', 'big tits', 'porn stars', and 'MILFs' are not good niches.

One of the common answers to this question is to pick a niche you like because it's easier to promote something you're familiar with and have an affinity for. That's not a bad answer because if you don't understand the Goth genre, for example, it's not likely that you're going to be able to promote it effectively. The problem with that answer is that for most webmasters, the niches they are most comfortable with will also be the most popular and now we're right back to the big drawback to promoting those niches, which is over saturation.

What are the best niches? The ones that aren't being over promoted yet are not so bizarre that only a few people on the planet will be interested. Obviously, Midget Mud Wrestling is not an over saturated niche, but then again, how many surfers do you actually think would join a site with that kind of content?

Another point to remember is that you need to be flexible. If you find a few niches that work well for you, it probably won't be long before other webmasters discover your little gold mine and begin mining in the tunnel right next to you, and the next thing you know, the vein runs out. When you see your sales slipping, don't stubbornly hang on. Move on.

I know that webmasters don't like to think of themselves as surfers, or admit to it anyway, but personally, I think if you aren't a porn surfer, you are going to have a tough time in this business. How else are you going to know what's going on? What's hot and what's not? If you want to find a good niche, do some surfing and use the search engines. When you think you've found a good niche, do some searches and make sure you aren't the only person that thinks so.

Next, do some looking to see if you can find TGPs that specialize in that niche. Look for toplists, linklists, directories or any sites that you can use to promote the site that either focus on that niche or at least have a category for it. Once you're sure you can get targeted traffic, find a sponsor with a website that features your chosen niche, and go make some money. And when you see someone post on a message board asking "What's the Best Niche?", tell them 'teens' and 'big tits'.
