well its javascrpit (adsense) and search engine bots cant search jvascripts and btw yahoo cant do that as it would get a lot of negative response from around the world and google could also do the same
I never thought about that. So does Google hate Yahoo and MSN ads. If so that just seems a bit un-ethical to drop rank for sites displaying these ads.
No, I don't think Yahoo & MSN care about this. There are just too many sites running AdSense to penalize them all
no that doesn't matter on your rankings or else majority of website will be not be there on yahoo or msn
I don't think that this exists. The ads by other network would not be under or over rated by other search engine. Most of the time google itslef mentions that google adsense and google search engine both are totally different things.
i notice that yahoo will demote you. i have a very good rank in yahoo, i used to have a Google Ads and yahoo remove me from top ranking. if i target yahoo search result i will not put Google adv.
if they did rank them differently it would be unethical for them. Also, it would undermine their entire ranking system. People would lose confidence in the SERPs.
