I try to find out how the system is working. WEIGHT!!! The weight based on google API results and number of ads what you implemented onto your site. You can use the google site - with command site:yourdomain.com(net, info, etc) - but the result not equivalent of the same value what the API tool provide. So, if you have a new site what G. not indexed your weight always is 0 so your ads (link) will not shown on the network. Your site must indexed on google before you can enjoy the advantage this network! Advice: 1. Go to http://www.google.com/apis/ and create an account. They send you a licence key via e-mail. ( If you have one and you need another one use another name and e-mail, your wife's for example) 2. Go to http://www.searchenginelab.com/products/gapis/ download this free tool and use command; site:yourdomain . If the results is 0, or the value is low, you have to working on G index. You have to "build" inbound links to your site on other ways. After your site is indexed you can enjoy what this network give you. Csaba
Nice post. You could also use the digitalpoint's free keyword tracker to figure out how many indexed pages that you have.
