Hello, I have a few site, my main site links to my future adsense site, would google care is the traffic is not related? example. my site cars.com links to linux.com would google penalize me? or what would happen? Regards
google would not care but the question is, will your car site visitor care about visiting your linux site and click on the ads? if the site/traffic is not related, then you will not get many people to click on the other site link
The answer is no. That's fine for adsense site which link to non-related site but promise they are not adult, gambling site that against adsense TOS
if google don't allow adsense on gambling related sites (one of which I have) why do they serve related ads on it, and pay me for it?
Google will not bother that as long as you have quality content on the site and don't look like a spammy site by linking out too much.
