Hi, I am afraid that using Adsense in my site could affect my yahoo, msn SERP. (If I am yahoo / MSN why would I drive traffic to a site that promotes my compettitors business). Just bringing two places down on SERP will hurt more than 30-50% of business. Same with using YPN. Google might downgrade my sites results. Anyone know for sure whether this is not the case? Best regards. Tony.
Thats good news. (still I am skeptical. Probably you will recieve more traffic if you drop adsense. But then what is the use of extra traffic if it doesnt bring some revenue..)
