Different Search Engines And How They Search The Web
The amount of the collection of facts on the Web is almost measureless
, and determining every answer that bears relevance in a humongous group of data can be tricky, in view of the fact that even the bulkiest search engines and Web directories would not even reach 20 percent of the entire 800 million pages out in cyberspace
What's the difference between a search engine and a searchable Web directory? Search engines such as AltaVista create Web site databases automatically by crawling through the Web and indexing pages by following all the links they find
A handful of search engines are considered a combination of both techniques, but yahoo among other Web directories, are people maintained
Due to multiple different factors, there is truth to saying that Web searching can sometimes be complicated Every search engine possesses its own advantages and disadvantages yet each also has a distinction of its own
Based on various groups of priorities, the response is formulated One of the determinants that search engines consider in accomplishing a list is to set apart the Web pages containing the keywords
They go to the top of the list of results if the keywords happen to be near the top of the Web page over even in the beginning paragraphs
Sometimes the subject keyed in would appear several times in the Web page and this affects its rank on the search engine result list, thus some Web writers will mention words on several times on purpose to cram up search engines
The way the search engine ranks the sites in the list is based on a lot of other considerations Meta tags, defined as series of HTML codes that bears information not visible to users, will fall under the list of ways for search engines to gauge the interest level of pages being ran for the search list
One of the Meta tags usually used is the keywords tag, which permits Web masters to stress the weight of particular words and phrases inside a page
Some search engines such as hotbot and info seek, respond to this indicator while others such as Lycos ignore it To spare themselves from the agony of repeating words on the Web pages over and over, companies use paid links so as to spam their pages to the search engines
Those who want to get the topmost position in the list just have to pay Simply typing the word books will bring about a search result where a widely known online bookseller will be named
A summary accompanies the Web address in the search results and it is also making mention that every time a person clicks through their site, an online bookseller gets to pay the resultant amount of a quarter, two dimes and a nickel
AltaVista joins the elite club of bigtime search engines by having multiple million indexed Web pages There is a problem due to the occurrence of links that will not bring out a result list, although the initial port is very efficient especially for beginners
It does not encompass enough, not even their intricate searches There are three ways by which your search can be done, Boolean search parameters with a little twist, prioritizing keywords, and specifying searches by date
Moving on to the next search engine, Google applies a text matching operation which is geared to screen and just return results that contains the keywords in the search field, a process many search engines miss out
It does not just bypass the linking pages' comments about it but rather takes a look at them Adding up to Google's special traits is Web page caching, which is defined as having the search engine save copies of Web pages that it links to
Last but not the least is Google's ?I'm feeling lucky? option which adds to why we can say Google is a very commendable search engine
Focusing on the getting the right result first is a skill Google has mastered so basic searches like company names can land directly to the relevant site rather than first going to the list of both relevant and irrelevant information
