If you are running any search campaigns in the USA or Canada you should be aware that this week that Bing is starting to take over the natural search on “Yahoo search” results.
Once this has taken place, in their own words
“Bing will power 5.2 billion monthly searches, which is 31.6 percent of the search market share in the United States and 8.6 percent share in Canada”.
If you are running US or Canadian Paid Search on Yahoo they also inform us that there is a transition tool available to help you migrate your account over to the Bing interface. You will be invited over the next few weeks if you are an existing advertiser.
If you wish to have a sneak preview of their beta tool, you can see it here –>The Microsoft transition tool
