Hi, I have built more than 100 blogs(12 domain names totally), and I have average $4.5 of daily income from google. I have reached my shared server account's max number of files. Which means the average ROI of my blogs is very very low. So I have some questions to ask below, hope someone can give me advice: 1. How do I make my blog's ads more related to my content? I found most of my blogs have unrelated ads because I put those blogs under one domain name. 2. How do I get more traffic besides usings tweet and suto social poster plugins? In this case, I have too many blogs. 3. How do I know what niche bring me most profit? I create blogs for hunderds of topics. And the average CTR is too low, it's pretty hard to know what blogs really get clicks, not just by accident. 4. Any way to upgrade one auto blog's profit to $10/day?
