Adsense on multiple sites and passing of PR

[ownerrim]

Just curious if anyone has thoughts regarding this scenario. You operate a site with adsense. You build a second site on some other topic and use the first site as the initial source of PR. Will running adsense on both sites be a signal to google that pagerank should not be allowed to pass from the first site to the second, since the adsense code would make it obvious that you own both sites?

[howiejs]

this is a GREAT question. Running adsense across your "mini net" or network of sites shows the ownership --- even if the hosts / whois is different!

K, scenario.

1. Find a competitor who makes lots of $$$ with AdSense.
2. Create a porn site.
3. Put HIS Adsense code there.
4. Use atomatic clicks software to make him some extra $
5. Watch Google kick him out of Adsense.

I don't think Google should use Adsense code for PR purposes.

I don't think Google should use Adsense code for PR purposes.

And I don't want them to, but do they?

[ownerrim]

right. in other words, do google-bot and mediabot sometimes have tea together and compare notes on what they've found in their daily travels?

[ogletree]

Google says no and I have never seen proof that they do.

Which means you're safe until you're not.

You can bet they keep the info. They may not use it. Perhaps not now. Perhaps not ever. Ormaybe they just want to keep the info in cases when they're chasing a SE spammer and only use it there. No way to know.

You would have thought that the same payee for both sites is a pretty good indication. But from message #3 above even same payee is not 100%.

There are tons of other ways Google can detect a "network"... from whois to your IP, to sophisticated analysis of links, to Toolbar, to the sites you do backlink checks for, to the IPs of your sites. Individually they sometimes may not reveal too much. Put them together and it's awesome!

Sorry... I get my own network with seven quality sites (good PR) on a server with the same IP and every one link each other in every page (more than 50.000) from january 2000. I got Adsense in every site from june 2003.

Where is the fault?
