10 Meta-Search Engines Reviewed and Compared

Meta-search engine is a web-based service that aggregates data from a number of search engines. A meta search engine doesn't have a database of indexed pages of its own. Instead it "sends a user's query to multiple search engines and blends the top results from each into one overall list."

Being in Search Engine Marketing, you may want to know how meta-search engines work, so here's a good reference source for you.

Some helpful features meta-search engines offer are:

  • search results clustering (i.e. search term grouping and classification based on the word derivations and phrases). Like I previously suggested, this feature can be effectively used for keyword research and brainstorming);
  • related term suggestions (also used for expanding keyword lists);
  • search terms linguistic and textual analysis (e.g. keyword definitions).

Besides, some newly launched meta-search tools offer a few really creative and innovative approaches: combining regular search engines and social media sites (e.g. FuzzFind) or outlining the results on a map showing the links between different search engines (Langreiter.com) , etc.

However, most (if not all) meta-search tools are no better than an individual search engine as neither of them seemed to develop an effective blending technology and relevancy leaves much to be desired:

Clusty Ask.com, Gigablast, Live, NY Times, ODP, Shopzilla, Yahoo news, Yahoo stocks Term clusters TLD stats Boolean operators (OR, -, +), filetype and language restricted search Low, too many "sponsored results" News,images, logs, shops
DogPile Google, Yahoo, Ask, Live Search suggestions (related terms); recent searches - Boolean operators ("", -) High Images, audio, video, news, Yellow Pages, White Pages

IBoogie AllTheWeb, MSN Term clusters "Add your source" option - Low Images, news
Kartoo N/A Search results on a map Term clustering - Low Images, video

Fuzz Find Google, Yahoo and MSN and from Del.icio.us Sort the results based on any of the sources - No High No

So does meta-search have any future? Well, it does. In today's web 2.0 (and emerging web 3.0) Internet there are plenty of promising ways for meta-search to evolve:

  • aggregate data from several search engines and rate them based on social media voting (e.g. Yoople);
  • blend several social bookmarking services;
  • make up a really unique blending and ranking algorithm;
  • aggregate data from different vertical search engines, etc.
