Google is making it easier for advertisers to send smartphones text and image advertisments that preserve their original design.
The move will help mobile publishers earn revenue and fund more mobile-specific sites and web content, Google said in a blog post this morning.
Sales of high-end mobile phones like iPhone, Android, Symbian and the Palm Pre already make up one of four new phone sales, and market analyst Gartner estimates that global sales of smartphones will soar by 27% in 2009, to 177 million units.
Most smartphone are internet-enabled, but different screen formats meant that not all ads appeared as their publishers wished.
The new advertising products include search ad options for high-end phones and AdSense for mobile applications.
Google said the new ad server will automatically detect whether the user is using a smartphone and serve the appropriate ad. This means publishers won't need to change their websites to target smartphones specifically.
