Google Inc., in an attempt to stretch out advertising beyond the computer-based Web market to mobile phones, announced on Wednesday the introduction of brand-image ads for mobile handsets.

According to a statement released on the Company’s website, the company said that the mobile images are designed in a manner to look like standard graphical display ads for desktop computer web pages, with the only difference in size.

The mobile image ads are said to be available in 13 national markets: Australia, China, France, Germany, India, Ireland, Italy, Japan, Netherlands, Russia, Spain, the UK, and the United States.

These ads are priced on a cost-per-click basis, and must have a linkage with web pages optimized to work on phones. The ads are targeted depending on the keyword entered by the user to search information.

“For advertisers, mobile image ads serve as a branding tool and have shown to have good click-through rates,” said Alexandra Kenin, product marketing manager.
