Is that the secret? Do I need to start blocking every RON ad I see?
As for ad targetting, I have used it, but it didn't get me anywhere near the "on-target" ads I get with AdSense. For example, some sites I have are B2B sites. But the ad targetting doesn't allow me to drill down far enough into the B2B category to make the ads relevant for the people reading the pages. The people who read my content aren't the people within a company who buy or make decisions about the things that are being advertised.
There are some pages where I would be willing to give YPN four days if I thought proper ads would show up. But many of my pages are time critical and my regular visitors find those pages quickly. Four days is too late - 2 days is too late.
But thanks for your reply. I think this tells me what I need to know. I may give YPN a chance on an unimportant page here and there. But in the meantime, AdSense is staying put until I hear that YPN has made significant improvements. I want YPN to improve and give AdSense some serious competition, but I'm not willing to knowingly sacrifice my income on their behalf.
