Google plans to extend the product search capabilities on its main search engine in the fourth quarter, in time for Christmas.

A Google official shared the news with attendees at the Professional eBay Sellers Alliance (PESA) Summit in San Francisco this week, according to people at the conference.

When people search for products on, the system will present them with another search box so that they can refine their query, wrote Bear Stearns analysts in a note published on Friday.

After people refine their query, Google takes them to a second page populated with product results from the Google Base listings service, wrote the analysts, who attended the Google official's presentation.

"Ranking will be determined by the attributes that the sellers listed for the product as well as by relevancy," the analysts wrote.

Currently, Google has no plans to create an income stream with this product-search capability through display ads or listing fees, but that could change, they wrote.

So long, Froogle

The plan also involves de-emphasising Froogle as a destination website and moving its comparison-shopping capabilities to, because, as the Google official explained, most product searches happen on, according to the note. can already detect if someone is looking for real estate to buy, and asks users to refine their queries before delivering listings from Google Base. Thus, the plan outlined at the PESA conference would apparently be a significant extension of this existing feature toward multiple product categories.

Jonathan Garriss, PESA's executive director, got very excited after learning at the conference of Google's plans. "Anything that improves product search and helps shoppers find what they want is always positive for a merchant like me," said Garriss, CEO of Gotham City Online, an apparel store on eBay that also has its own site.

Garriss already feeds product information from his store to Google Base. But after talking to Google officials at the conference, he plans to improve it. "It will make it a it smarter search. Google is giving us an opportunity to do that," Garriss said.

PESA groups about 600 large eBay sellers that collectively generate over 70 million eBay transactions and $1 billion in eBay gross merchandise volume annually.

Base station

Google Base was introduced last November as a service for individuals and organisations to post content to the Google search index, including products for sale.

From the beginning, Google said that Base isn't meant as a destination site, but more like a database to feed information to Google search sites, like To stress this point, Google recently removed the search box from the Google Base site.

The Bear Stearns analysts didn't immediately reply to requests for comment.

A Google spokeswoman declined to comment, saying only that Google has integrated content from Google Base, and from other Google products, into search results for some time.

A recent sign that Google was working on its product search was the removal of the link to Froogle on, said analyst Greg Sterling, of Sterling Market Intelligence.

"Everyone was surprised and Froogle's traffic immediately suffered, but Google wouldn't opt out of the shopping search space," Sterling said.

Presenting product listings via is another move by Google to integrate vertical search services on its main search engine, which is by far its most popular site, Sterling said. In addition to real estate listings, also detects searches for topics like movies and recording artists, and treats them with special results.
