Different Types of Search Engines
Written by: Diane | September 9th, 2008Search engines have different ways of searching through your website to find out which results you should be ranking for, and how high. There are 3 types of search engines;
Crawler- Based: A 'Crawler' or 'Spider' automatically crawls through the code on your website to search for keywords and other information which helps them identify whether your website is relevant enough for pages to be indexed on the search engine. Your website can be crawled and still not have pages indexed, you can check this on Google Webmaster Tools. An example of a crawler search engine would be Google.com
Human- Powered: These types of search engines, such as Open Directory, depend solely on people to search through websites and create listings. This takes much more time and these search engines tend to have less results pages, although those results may be more specific to what you are searching for
Hybrid: These are a combination of the two types of search engines described above.
As well as the different ways that search engines search through your websites, they also take into account different factors that they find. For example, some search engines take into account the On-Page SEO, and others Off-Page SEO, Site Design, User Analytics, Structure or Links.
More information about all of the above is given in our SEO Training courses, or during an SEO project.
