Yahoo is currently testing Bing powered ads, on paid search amounting to about 3% of all searches made on the Yahoo network. Yahoo has been kind enough to provide a PDF document that outlines the key differences between the adCenter platform and the Yahoo platform. This was released in a effort to transition advertisers smoothly to the new Microsoft adCenter, which currently is the least used of the 3 largest search engines (Google, Yahoo, & Bing).
Here are some key differences between the ad networks that you’ll need to know:
- Distributing is done on the ad group level with adCenter, but account level with Yahoo.
- Microsoft will enable the same domain blocking capabilities by the time Yahoo is transitioned over.
- Microsoft offers more (better) match types than Yahoo does, giving more control to advertisers. Yahoo has been know to have very liberal match types which some advertisers don’t like.
- Microsoft’s keyword mapping is more normalized, so you will likely need to add more keywords to your adCenter campaigns, but it does give you more control.
- Geo-targeting isn’t very robust in adCenter, whereas Yahoo works well with this.
- Microsoft will add more negative keywords to adCenter, matching Yahoo’s current limits.
- Ad title copy length is 25 characters on adCenter, from 40 characters on Yahoo. Titles will take a drastic cut in characters.
- Minimum bids are 5 cents on Microsoft and 1 cent on Yahoo. This most likely won’t affect many people.
