This month, the company introduced a search-within-search feature that lets users stay on Google to find pages on popular sites like those of The Washington Post, Wikipedia, The New York Times, Wal-Mart and others. The search box appears when someone enters the name of certain Web addresses or company names — say, “Best Buy” — rather than entering a request like “cellphones.”
The results of the search are almost all individual company pages. Google tops those results with a link to the home page of the Web site in question, adds another search box, and offers users the chance to let Google search for certain things within that site.
The problem, for some in the industry, is that when someone enters a term into that secondary search box, Google will display ads for competing sites, thereby profiting from ads it sells against the brand. The feature also keeps users searching on Google pages and not pages of the destination Web site.
