I am beginning to suspect that Google is already acting on co-op sites with high weight.... If you are running a high weight co-op advertisment, check your main target pages cache in Google and report back to this thread.... I'm noticing suspiciously long delays in page cache on sites with high weight.... I've already checked a few I know of in the game and there caches are aswell suspiciously long overdue... My last cache on target April 20th, way too long...
I run co-op in a sub-directory on my main site. It has PR5 and over 150k pages. That's over 25,000 weight. So I guess it is high. The index page of the directory is showing 4 May 2005 03:35:27 GMT The index page of the site itself is showing an older chache of 28 April. No ads on there.
Wherever the ads are pointing too, the target.... so index should be your homepage and our saying april 28... not too bad, but mine shoud be daily and it's way back there..... weight 20,000 checked another 50,000 weight site, same thing... another bigone too, but I'm guessing it's a big weight..... When more people respond we see what everyone thinks...
What exactly are you saying? Are you saying that you are pointing all of your ads at the home page of one site?
When I was running co-op ads I noticed that I had cache dates of 10 days or so. This is really long, and my content does update daily. I would collect weight from my main domain and then push ads to certain pages one directory under the domain with various anchor text (never using all the weight with one anchor).
My cache dates are mostly the 28th of April (Were the 18th up until a few days ago) but in order for this thread to be useful you need control sites that don't have the Coop pointing to them. In my case my other sites have the same Cache dates on most pages
Google has been having a problem keeping updated caches of pages, period! I have brought this up in this forum as well as another forum. The experiment page I have been documenting has had 4 times within the last year when Google "forgot to update" it. The longest period was last summer when the page went from June 22nd to August 20th without an update. During that time the page slipped from #25 to NOT FOUND in Google. This last time Google "forgot" it from April 20th until May 3rd. Each and every time this happened, I had to open the source of the page, save it, and re-upload it to the server. When I did this Google updated the cache within hours. The page I am talking about is not in the co-op. You can read about it here... Watch Your Cache Dates!!!! Caryl
