DogPile.com is technically still live, and today it fetches results from Google, Microsoft Bing, Yahoo!, and other search engines. It’s largely a relic of the past, and we’re keeping our previous reporting on it live on our site as a time capsule of sorts.
Up to three quarters of their search results are pay per click listings from Google, Yahoo! and Bing. They also have a relationship with the people at WordTracker, enabling members to access data about which phrases are being searched.
Dog Pile is a “meta” search engine – it querries multiple search engines (Google, Yahoo! and Bing) and gives you pages and pages of results, indicating the source of the result inline. Unfortunately, too many of those results are paid listings for the search to be of any real use.
A typical search results page includes approximately 20 results. A search for “seo services” resulted in a list of 21 results, 16 of them sponsored links.
Dogpile Web Search is part of InfoSpace, Inc., which also owns MetaCrawler, WebCrawler, WebFetch, all meta search engines.
