Thank you very much Alex for your advice.
Does anyone has any idea about Yahoo/Overture?
I believe Overture feed has more Ads and better RPC for where I live, so far.
If you check
www.assistant.com, you will see they are using Overture feed and I don't recognize their template from any PPC company, so I assume they got their own direct account with Overture.
The reason I am interested in is not just possibilities of getting more cut by dealing directly but also possibilities of controlling/optimizing for my own needs. In assistant.com, I see Korean ads and localized targeted search results and I guess it is because I am visiting their site from Korea. In contrast, I see no localized/targeted ads in my parking page in parked.com.
I used to park at namedrive which use Google feed. Their localized ads were OK but since couple months ago, the revenue dropped to alomost none. I guess they blocked click(not traffic because I can still reach my parking site and see localized ads provided by Google) from where I live. Which doesn't make sense because I parked all my Korean ccTLD domains.
I wish I could have parking pages like assistant.com so I can park all my great ccTLD domains. Well, I can guess there will be a lot of headaches if I want to deal directly with overture but what the hell! I want to know, at least.
