Search Engines

Search Engines
 
What would I know about them? As much as the college textbook for computer science majors tells me I suppose, if I read it completely. But even if I do, I am too old to bother about exams, so I will truthfully have to say "I know nothing of interest to software designers."
 
What the college textbook in fact has to say is that search engines make use of techniques of computer science known as far back as the 1970s. The layman will find very little of interest here; the working programmer knows more than the book.
 
I have written something about the development of the internet in my lycos page, which refers to geocities help files for further information on search engines. As it happens, geocities is soon to close, so I have to rewrite in my own words most of this information here in anticipation of my link turning obsolete.
 
  • Definition A search engine such as Google, is an online tool that helps users of the World Wide Web find the sites and information that they are looking for. The user enters  a word or phrase into a search box, and the search tool displays results that are generally organised in order of relevance. Most search engines use automated programs (sometimes called spiders or search crawlers) to look for relevant information based on the users’ keywords, and search not only web sites’ content but also their web addresses, number of pages, and links.
  • Note The Yahoo! Directory is not a search engine. Placement and inclusion are determined by Yahoo!’s editorial staff.

The help files note that

"Search engines change their page ranking and relevancy formulas frequently to keep sites from artificially boosting their rankings above where they would normally be based on their content. The trick that works to boost your ranking today may actually in the future based on changes that are made.

One example is the keywords meta tag."

The article "Death of a Meta Tag" is cited.

  • Definition Meta tags are little bits of HTML code that provide information about a page but are not visible by the user in the browser. Most search engines examine a page’s meta tags, which usually include a page title, description, and keywords, to index the page and help determine its ranking in relevant search results. Although not the only way to elevate your site’s search engine rankings, adding meta tags to your pages can help.

Page ranking and relevancy formulas are in fact the innovation of Google, and finally led to the dominance of Google over other search engines.

The normal web user will be ordinarily interested in how to make the best use possible of existing search engines. From the point of view, what geocities has to tell web site owners is the following:

  1. Organise Your Site, and Say something!
    A well organised proffessional looking web site will attract visitors, encourage them to stay longer, and prompt them to refer their friends.
  2. Create Links
    When determining determining your site’s ranking in their results, many search engines consider the number and quality of links on and to your website.

I don’t know whether the information in this posting, which contains only two links will be of any use to the reader!
