What I've been doing is extremely simple but it came to me a few months back and it's been working like a charm for me. Yes it's extremely simple and sounds obvious but if you're going to hate on it then keep moving because I'm making an awesome ROI doing this. I started noticing that almost every time I logged out of my hotmail account and was forwarded to msn.com, there was the exact same ad in the exact same ad spot. It was one of those "eat this and lose weight" type of display ads that shows a close-up of some type of weird looking food and you can't really tell what it is. The idea here is to make people click out of curiosity and then attempt to hook them with something either in or after the article they wanted to read. So anyway, I knew msn was a high volume site so the person running these ads was obviously spending a lot of money on the campaign considering that I was personally coming across the ad this often. Then I decided to try copying this exact same strategy with a VERY similar ad. Then I made the site I would use for my landing page, which was also very very similar and I utilized the exact same monetizaton strategies as the other guy's site too. The hardest part of this process was securing the advertising space on msn because I needed to use either the same ad space as the other guy or a very similar ad space. I ended up settling for a different, yet similar ad space and ran my campaign 24 hours a day (intermittently) so I could see which hours were most effective, if any. This particular campaign was turning almost a 450% profit right off the bat without optimizing anything, just running the campaign 24 hours a day. Enough said. Since that campaign I've copied 7 other campaigns on slightly smaller websites and 5 out of the 7 ended up being very profitable. The other 2 sucked for some reason but it only cost me $50 to find that out, so who gives a shit. I just dumped them and kept the other 5. Of those 6 campaigns, 3 of them are still running as we speak and are still profitable. The key here is being able to recognize an ad campaign that is running A LOT for several consecutive days, and then following that ad and see if the person is still running it a few weeks later. If they are, copy it. Everything. The ad itself, the landing page, the strategy and monetization method(s), the website and the ad space. If you can't beat or share with the guy currently in that space, use the next best ad space available. But don't deviate from the campaign you're copying unless you're an expert in a certain area and think that something else will work even better. Otherwise, remember that this is based on copying something that's already working and doesn't need to be messed around with. Sometimes weird things work so even if something seems odd with their strategy, copy it anyway and see if it works. You should only make very slight changes where it's necessary so you're not literally copying everything cause obviously that's not gonna fly. There's a lot of detective work involved here and you need to get good at recognizing a winner, but it works for me.
