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.

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

using other engines' results); Have integrated directory linking to

enginesno way other than to pay a recurring or one-

time fee to keep your site either listed, re spidered

Search networks are often set up in an auction environment where keywords and phrases are associated with a cost-per-click or PCP

Page 16: Search Engine Optimisation

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.
