Web search leader Google Inc's global sales chief sidestepped questions on Tuesday over whether its foray into graphical display advertising has been a disappointment, saying the effort remains in testing mode.
"I think it's fair to say we have basically just started," said Sheryl Sandberg, Google's vice president of global online sales.
Sandberg was responding to a question from analyst Safa Rashtchy at the Piper Jaffray Global Internet Summit in Laguna Beach, California, about whether the company had gotten off to a slow start in its display ads business.
Her comments were Webcast on Google's investor relations Web site.
Google derives virtually all of its revenue from selling pay-per-click, text-based advertising as opposed to display advertising, such as banners on an Internet page, a market that rival Yahoo Inc continues to dominate.
The company has been experimenting for two years with running graphical advertising on affiliated Web sites supplied by Google rather than testing ads on its own search results pages.
Last month, it introduced a plan to offer "click to play" video advertising.

Rashtchy asked Sandberg whether Google planned to offer ad services to cover "all media," including the broader world of traditional media outlets.
Sandberg declined to specify in which additional media formats Google was prepared to offer advertising.
"Our long-run vision is that we will be working with advertisers ... in lots of formats," she said.
"I don't think we know how we will do it," the Google executive said. "We don't believe we have to have the perfect answer before launch."
Sandberg declined to comment on Google's ad sales, citing the company's policy against commenting on its future financial outlook.
Google shares rose $1.46 to $383 in Nasdaq trading.
