The term ‘search engine,’ including Life Science SEO, is referred to as a program on the Internet designed to search information on the World Wide Web. Broadly speaking, a search engine is characterized by crawler-based search engines, human-powered directories, and hybrid search engines. All these three types of search engine collect the information in their own devised ways, i.e. by means of
- crawler-based searches
- human-powered directories
- hybrid searches
Crawler-Based Search Engines

A normal or standard web query hardly takes less than a second. However, there are several different processes involved before the query results have been delivered to the information seeker. Following are given steps which are required to be completed before delivering the query results to a person seeking any particular information:
- First, the query is sent to the index server by web server. Index servers usually contain the content similar to the way it is given at the back of a book. Index servers help to find the pages containing the keyword.
- The query is then sent to the doc servers where the stored documents are retrieved. For each query result, snippets are created.
- Finally, the query results are delivered to the user.
Human-Powered Directories
Human-powered directories or human-powered search engines like Open Directory Project (http://www.dmoz.org/about.html) usually based on the human listings. Directories are designed slightly different than search engines and the site indexes of directories are also different from search engines. DMOZ as mentioned above and Yahoo! are the two most suitable examples of web directories. Both these directories deliver results according to the category. Both the directories comprise of millions of indexed sites. The directories usually searching the results in the description yielded.
Hybrid Search Engines
Hybrid search engines are the search engines wherein crawler-based and human-powered search engines are both involved in a single query. Hybrid search engines normally favor listings over one another.
