we've have similar problem about the ads. Thanks for the tips here that you share duds. One thing that i ask to all concern , how is it important to have a good traffic in alexa and pg in google before you get to monetize your blog.
To be brutal, you say on your header "Another technology blog" and that´s just what it is; another blog in an overcrowded marketplace. There is nothing there to encourage people to explore the site. Your use of English is poor, and that doesn´t encourage people to "trust" or "believe" what you are writing. You have very few backlinks to your site, and this will not help with your ranking or your traffic. The layout, although fairly clean, is extremely boring. There is nothing on the page that screams "LOOK AT ME!!!" This is not intended to be a personal attack or anything like that. I hope it is constructive critisism. If you don´t think it is, then I apologise in advance.
To all the experienced and knowledgeable folks out here: I too have a small blog and I am not earning much out of it. Can we enter a mutual set-up wherein we click each other's ads on a periodic basis? Is this feasible?
Few Quality post with good keywords can drive good traffic to your site. Place the adsense ads in different format and color and do a research
