Yahoo Search Run by Bing

The bid landscape will not make much sense in the beginning of this new environment, so having some baseline performance prior to this period on MSN's Bing will be a competitive advantage. Any quality score or historical data from Yahoo probably won't be moved to MSN. If you are not expert on bidding for keywords and phrases, it's crucial you test carefully to not completely blow an ad budget. A smart strategy is to be positioned where people are spending most of their time on the internet- their social networks. Social media advertising can be targeted according to demographics. Contribute content and get involved in social networking. This will help you build brand recognition, credibility and visibility and help a ppc campaign get better conversions. If you choose to run on Yahoo only, including their partner sites is coming soon. This will help an advertisers' performance. Yahoo has taken it a step further to allow advertisers to run on their partner network only. This additional targeting tool may help niche players who want to bid specifically for a Yahoo network partner. This can be done by targeting the Yahoo partner network only, and then blocking referring sites that don't match their criteria. The ability to block poor referring partner sites can greatly improve results and that's different compared to Google.(excerpts from SEW)
