Hi, I know its an old thread but I want to share my experience. Im using sedo for parking. IT depends of where "viewers" will click. Some ads worth more. I have a killer name that recived 13k views a month and another about 3k. The ratio off earning vs views with the killer name is way less than the other. Both haven't good cpc. The key is to have a domain that will make users click on ads.
One is a online streaming website "typo" that I registered 1 year before the other website when out! I guess my domain is better haha. Im usig the 2 click method beacause it shows "categories" so they click once then they click on a ads.
With the second one I use 1 click beacause the name has lots of backlinks redirecting to it so viewers click on a link they found (my domain) then they try to click the ads that they are looking for.
Tip one, get a good name.
Tip two, choose the right category for parking
tip 3, choose the best template and type of ads.
hope it helps
