Yahoo's new tools match users and ads

Yahoo is about to announce new tools to help marketers target their online adverts better, The Wall Street Journal  says.

The new services include presenting graphical adverts to users who've used Yahoo's search engine, customizing offers based on which web sites a consumer has visited and what they have done on those sites.

Another service that is expected to go live next month will allow marketers to buy text adverts next to search results that are targeted to users during a certain time of day or based on factors such as their age and gender, according to the paper.

At the announcement, Yahoo is to urge marketers to stop thinking about search and display advertising as separate products and to take advantage of the tools to bridge the two, Yahoo execs told the WSJ in an interview.
