Classification of Search Enginescrawler-based (traditional, common) search engines
o Crawler based Ses, use Special software “bot” to automatically and regularly visit sites and create and supplement their web repositories(where data is stored and maintained for future retrieval).
o When Crawlers have found a page to scan, it retrieves this page via HTTP (like any ordinary Web surfer who types an URL into a browser's address field and presses "enter")
o Crawlers give more value to text that's closest to the beginning and end of the page, and the text wrapped in links.
Classification of Search Engines 2directories (mostly human-edited catalogs);Pages that are stored in their repository are
added solely By manual submissionrequire manual submission and use Captcha
images to protect from robot spam and verify Human entrys
When directory editors visit and read your site, the only decision they make is to accept or reject the page
Directories do not have Ranking systemsBest Knon directoires - Yahoo and DMOZ
Classification of Search Engines 3hybrid engines (META engines and those
using other engines' results); Have integrated directory linking to
them(Dmoz,Yahoo directory)directory generally depends on a mixture of
luck and content quality. Sometimes you may "apply" for a discussion of your website, but there's no guarantee that it will be done Or you may need to Seo your site
Yahoo and Google are in fact hybrid engines
Classification of Search Engines 4Meta Search Enginescombines results from a number of search
engines at the same time lays them out in a formatted result page’sallows the user to cover a great deal of
material in a very efficient wayMetacrawler uses seven of the most popular
search engines including “Altavista and Lycos”
Dogpiles is also a meta SE
Classification of Search Engines 5pay-per-performance and paid inclusion
enginesno way other than to pay a recurring or one-
time fee to keep your site either listed, re spidered
most major search engines offer a paid listing option(yahoo directory)
Search networks are often set up in an auction environment where keywords and phrases are associated with a cost-per-click or PCP
What you need to knowSearch engines (SEs) are classified into crawlers,
directories, META engines and paid-inclusion engines. Crawler-based SEs use software called robots, spiders, or
crawlers to add new pages to its database which is called an index. Directories use humans to manually fill their databases.
After your site has been included in an index of a crawler-based search engine, you will appear in its results, and your position for a certain search query depends on how relevant the spider finds your page for this query.
Your directory listings are quite influential to your positions in crawling search engines.
