I have no idea what weight even is or how it works. I tried searching google but all I got was lose weight now...Can someone help me out?
You can read through here: http://www.digitalpoint.com/tools/ad-network/ It is basically the amount of "power" you have within the network
It is a calculation of: PR Number of Pages Indexed Number of Ads That weight determines how often your own ads are shown
Then your weight will be displayed there. As far as changing it for the better you can: Get Google to index more pages Get a higher PR (see this forum for tips although basically you need more links to you) Put up more ads (5 is the limit)
