I recently found a killer niche (im not sharing) I first made a site targeting my country, which has been doing really well. I am now working on the same sites with geo targeted domains. Here are a few tips that I have to share about what makes this site do so well: Its a solid niche, about 15 000 searches a month, with no direct competition The site basically gets the user to fill in a form to get the info they want. The form could be done and processed on 1 page, but instead i drag it out to 7 pages. Each page display a few ads and other content, which get randomly positioned in a few divs, as in the ads on the first page are not in the same place on the second page. This increased the CTR nicely, because peoples eyes normally spot the ads, and then ignore that area while on the site. By moving the stuff around, people are forced to read the ads. Try it out on your sites!
