UPDATE:Hello again, everyone

...
We've been talking about how ad-placement can noticably affect your Google AdSense revenue -- both in a good way and in a bad way.
This time, here's what one guy did to his personal Website, and how it affected his Google AdSense revenue...
Thomas Zehetner is a german fellow who has his own 'technology news' portal,
PCFreunde.de . This has been only a "hobby" Website; Thomas used to do it merely because it's fun for him. But when he heard about Google AdSense, he decided to give it a try. There were actually some results, but nothing as spectacular as he would've hoped for.
So he decided to changed his ad-placement from the side of his pages and "into the content." Now, this is important. Remember when we talked about GPSWorld.com? This wasn't a "content" Website; it was corporate. Their content was only interesting for people for are actually looking for a certain product with a purchase in mind.
But Thomas' Website is different. It IS a content Website. His visitors come back to his Website because he provides information they'd like to know and stay up-to-date on it. So you see, when people visit his Website, they "focus" on the content. They don't want to be distracted by looking at Sidebars, Top-Banners, or any of that. Their eyes are riveted to the content itself, and the content alone.
So when Thomas placed the AdSense ads INSIDE his content, what happened to AdSense's revenue? Well, it
tripled. Yup, that's right... three times more.
So what's the lesson we can learn from this? Simple, really. Content Websites have much, much better chances of promoting anything they want to as long as they make sure it shows IN the content itself. Of course, that requires that you first offer great content with amazing value so that people actually WANT to go to your Website constantly to read it.
All the best,
