Google Base gets the latest push with Google adding a search box to certain results where users can easily search within the SERPs they just retrieved.
Loren Baker at Search Engine Journal noted some commentary from other search bloggers about the latest search within search from Google:
Scubajarhead on Webmaster World: “This is going to turn into a nightmare especially for the real estate searches. Thousands of real estate agents are just going to bulk upload data from the MLS and just cause a load of duplicate content.
“My clients spend thousands of hours creating unique content for their websites to get a first page listing for terms such as [large city] Real Estate. Its is very disheartening to see now Google directing traffic to their own product right on top of the natural listings. I think Google is heading down the wrong road with this addition to the SERPS. “
Philipp Lenssen sees this as another step toward Google Base directly competing with eBay:
It is getting closer to eBay Motors, certainly. A search for Honda Odyssey, the popular minivan, brings up a similar set of search boxes allowing the user to look for an automobile by location, make, and model.
