yes it does increase you weight to increase number of coop links. There is no documentation as to the calculation, so you will just have to test it. Good luck...
From what I have read three things influence weight, number of pages Google has indexed, pagerank of site, and number of ads per page.
Thanks for your answers. But doesn't that mean to become big I have to be big? I always read about weights above 10,000 in this forum and I do have only about 700 - collected from 5 websites. Can I get somewhere at all with this little weight? And what can I do if my site is relatively small? I'd like to keep it small because no one reads all that stuff. Generating a thousands pages site doesn't help anyone (only my weight :-( ???).
You will get somewhere however the amount of links will be small. Many of the users here with large amounts of weight will probably get it from 3 possible places Owning forums (Nintendo does that I think mainly) Sites that grab content from RSS feeds A large site which they have spent years creating Or somthing else
You can add.... A large site which they have spent an hour creating. Heck, five minutes if it's a script site like an Amazon site. (Made for co-op pages. Exactly the same thing as all those made for AdSense sites.) It's not very hard to go to the content section, buy content and get 20,000 of fat from it when it gets PR....if it stays indexed and has nice PR, like 5 or more.
I never heard that number of impressions figures in in a direct weight. Expect number impressions is actually a function of weight.
