Mainly 3 types of Search Engines are seen
1) Crawler-Based Search Engines - Crawler-based search engines use automated software programs to survey and categorise web pages. The programs used by the search engines to access your web pages are called 'spiders', 'crawlers', 'robots' or 'bots'.
2) Directories - A 'directory' uses human editors who decide what category the site belongs to; they place websites within specific categories in the 'directories' database.
There are two major directories
Yahoo Directory (www.yahoo.com)
Open Directory (www.dmoz.org)
3) Meta Search Engines - Meta search engines take the results from all the other search engines results, and combine them into one large listing. Examples of Meta search engines include:
Metacrawler (www.metacrawler.com)
Dogpile (www.dogpile.com)

Search engines ask for keywords or phrases and then search the Web for results. Some search engines look only through page titles and headers. Others look through documents, such as Google, which can search PDFs. Many search engines now include some directory categories as well.
Here are the most popular search engines:
- Google;
- Bing;
- Yahoo!;
