For too many years, Yahoo is always second, behind search giant Google. Yahoo has always been the follower of Google such as its successful adsense and adwords program. However, it looks like Yahoo is finally leading a new way in its recent launched of SmartAds, an advertising product that will allow marketers to offer custom and relevant advertisements on the fly based on a user's behaviour.

Here's how it works, for example, if a user is browsing for hybrid cars in Yahoo Autos and had previously selected San Francisco as his or her default location in Yahoo Weather, Yahoo's SmartAds platform can assemble and deliver a display ad in real time to showcase a hybrid vehicle from a major auto brand, as well as local dealer information and current lease rates.

Yahoo SmartAds will utilise demographic, geographic and behavioral targeting to create more Relevant Advertisements for the user. Using the new technology, ads will be created on the spot, utilising several known factors about a user, including recently-visited sites, location, age, and income. The search engine's recent $680 million acquisition of Right Media will allow SmartAds to appear on the ad provider's extensive advertising network
