Ask.com is currently the fifth most popular search engine on the Web. It lets users search the Web for links, images, videos, driving directions, and news, along with local city listings and shopping links for products.
In a space so heavily dominated by Google, Ask.com does one thing that no other search engine does: display results from other search types on the same page. This lets you see a wide gamut of results, all at once. It also differs from other search engines in allowing users to customize and skin various elements of the engine from a large catalog, which changes the look and feel of the site entirely.
Ask.com is also the proud owner of Dictionary.com, Thesaurus.com, and Reference.com, though the company has not integrated any features of those sites to the search page. With current competition from Bing, it remains to be seen how Ask.com will fare going forward. It's simple enough to use, but may not have enough incentives to keep users coming back.
