I posted my question in the Adsense review forum but only got 1 response so hopefully I can get more this time. My website is www.myspace-crash-codes.com It is high in traffic but the CTR and eCPM are dreadful. I recently changed the site theme so I'm wondering if that could have caused the huge decrease in earnings. Can you check out my site and tell me some different ad placements maybe to better optimize the ads?
People looking for myspace stuff aren't going to click many ads that aren't related. Your adsense block currently have 0 related ads. I would try an affiliate that might match your target audience.
You might also try adding the unrelated advertiser urls to your filter. In your AdSense account you will see a competitive ad filter where you can enter urls of sites you do not want ads to appear for. It may be that there arent enough related advertisements, but you could try the filter to see what happens
In my opinion, swap the places of Expert Articles and Free Articles Directories. I feel it will be better, and will give you better targeted ads. Try optimizing the webpage to get targeted ads. It may just work.
