Yahoo Site Blocking will allow advertisers to define up to 250 sites or pages they want to not display their ads on. So if you do not want your ads to show up on the sites or pages of some Yahoo Publisher Network sites, you will have that granular control within a few weeks. Google also has this feature, by the way.
Most advertisers are excited for the launch of this feature, as portrayed by forum threads at Search Engine Watch Forums, WebmasterWorld and DigitalPoint Forums. But some are skeptical it will work for their benefit, at least right off the bat.
I won't hold my breath that it will work. I tried the blocking they can do now and it had a negative affect on my client's account and Yahoo could not explain why. How can I block aprox 300 clicks per day with 3 conversions and have the account clicks RAISE by more than 300 and conversions were cut in half.I had them remove the blocking and the account showed improvement
I would suggest great CAUTION when first using this feature. They still haven't gotten some publishers to UN-MASK their traffic that STILL shows in teh Non-reffered category when it is truly REFERED traffic. How can blocking go into place if that has not been resolved?
I will try the blocking again, but I will do it ONE publisher at a time until I figure out which ones cause problems when they are blocked........
