Microsoft enriched mobile advertisement
Microsoft is following Google’s and Yahoo’s lead in placing click-to-call advertising on its Mobile Windows Live search. MSN is planning to display a click-to-call ad above the search results, making it easily accessible to the user.
Ad-to-call ads complement mobile search, since users are already using a phone. Users can click on an ad to place a direct call to the advertiser.
MSN is partnering with Ingenio to provide the ads for mobile search requests.
