Metasearch and vertical search engines

[dimpy.handa]

Some web sites are simply search engines that collect results from multiple independent job boards. This is an example of both metasearch (since these are search engines which search other search engines) and vertical search (since the searches are limited to a specific topic - job listings).

Meta search engine submits your query to several other search engines and returns a summary of the results. Therefore, the search results you receive are an aggregate result of multiple searches.

Vertical search engine is a Web-based search engine that indexes content specialized by location (local venues and activities), by topic, typically for consumers, or by industry, geared to businesses (B2B). Instead of returning thousands of links from a query, as is common on a general-purpose search engine such as Google and Yahoo!, vertical search engines deliver more relevant results to the user.

For each search query search engines typically do most or all of the following

Accept the user inputted query, checking to match any advanced syntax and checking to see if the query is misspelled to recommend more popular or correct spelling variations.
Check to see if the query is relevant to other vertical search databases (such as news search or product search) and place relevant links to a few items from that type of search query near the regular search results.
Gather a list of relevant pages for the organic search results. These results are ranked based on page content, usage data, and link citation data.
Request a list of relevant ads to place near the search results.
Searchers generally tend to click mostly on the top few search results, as noted in this article by Jakob Nielsen, and backed up by this search result eye tracking study.
