Although I not a professional SEO guy, here are few things I've learned in 5 months of IM and I would like to share them with you; 1. .info domains can rank well, but they require a little bit more work, preferably white hat. 2. Even if you have a traffic peak, if the articles are shitty written, the visitors will exit the site quickly; 3. In some cases, Infolinks can be better than Adsense. Even if the CPC is low, at least there way more clicks (in my case); 4. even if you are some minor grammar errors but still have a good and informative content, visitors will stay and read and even comment or submit the articole to their social media accounts; 5. Yahoo Answers is a great way to get traffic, especially if you have multiple sites and you do not post links to the same site all the time. Moreover, if you spend some time on giving helpful replies, then other people will get on your site; 6. Do not expect to make huge sales with Amazon, especially if you have a new review site. 7. It's important to learn how to make keyword research, or otherwise, you will find out that your micro niche is harder than you expected. 8. Pay attention at your page loading time. If your page loads extremely slow, analytics may count the visitors, but they won't have patience for your site to load. 9. There is no such thing as luck. You can't big clicks, huge affiliate sales and lots of fans in the same time, especially if you want to do this without investing anything. Next set in 5 months from now on.
