1. Yea the Heatmap can def. help you, but if that doesn't work don't be afraid to change the position of your ads again (its all about experimenting) 2. Also things like having the right format will help. The large rectangle is used a lot and from experience is the most effective. (Note: I don't know if you have already applied this since on this PC + Browser the Ads are blocked) 3. And yes quality, unique content (Make sure to add some of your own personality to them instead of copy pasta) will help. 4. Stick to a shedule for more loyal visitors (Also benefits yourself). 5. Also color; choose a color that goes well with your background/site (Makes it look like Adsense is a part of your pages/Can result in more clicks) 6. Alternative to 5, you can also use Red Titles with a black description, + the blue/red URLs (Also widely used and effective). Those are just a few tips that have been proven effective (But as I've learned, experiment). I have a detailed guide about everything related to increasing your income but I'm not sure if I can link to that or anything so I'll keep it at that. Good luck!
