I have pulled the COOP from all my sites untill this mess is worked out. I have one pr4 site with 75,900 indexd pages with a weight of 162. That is horrible. Also the weight that the site above had was pointed to another site, and now that the weight is gone the second site is not showing any pages in google now. There needs to be another way for the COOP system to assign sites the correct weight, because google is certainly not the answer anymore. There needs to be a backup plan. Though some might dissagree, but google could be checking who runs link networks by doing exactly what they are doing now with the index. I predict that it will only get worse.[SIZE=-1][/SIZE]
Not sure if this problem has got to do with the coop weight. http://forums.digitalpoint.com/showthread.php?t=86819
From that, I go back to the part where google could be checking for the COOP and other link networks that use the site: operator to generate weight value. Breaking the site: operator for a short time would be enough for google system to see which sites had a large decrease in backlinks and then tag them as being in a link network.
would not work , as backlinks would not decrease because there would still be the same number of ads in the system as weight is relative. So if you had a coop of two people with 5 weight each its the same as having two with 50k weight each. having more weight in the system does not create more ads in the system.
Google is messing up with webmasters. don't reasons. First 4/4 pr update. and now index pages problem
