(Xinhua/Agencies) In a bid to strengthen its online adverts and attract users, Yahoo Inc. will launch several tools Tuesday to help marketers better use its services amid global meltdown.

Yahoo senior officials in a Wall Street Journal report were quoted as saying the new services include targeting graphical adverts to users who have searched for particular terms in Yahoo’s search engine and customizing the offers in adverts based on what Web sites a consumer has visited and what they have done on those sites.

Yahoo, the leading provider of online display advertising, has been under pressure for nearly a year following unproductive merger talks with Microsoft Corp., Google Inc. and Time Warner Inc’s AOL.

‘Targeting a site with a couple hundred thousand users…I don’t call that targeting. I call that wasted effort,’ the paper quoted Joanne Bradford, Yahoo’s senior vice president of U.S. revenue and market development, as saying. ‘Size does matter.’

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.

Bradford and Michael Walrath, a senior vice president at Yahoo, will discuss the new features during a keynote address at a conference in Orlando, Florida, on Tuesday, the paper said.
