Search Engines

If a web search engine was "drawn" on paper, it might look like a sun with lines for rays (links). Plus, superimposed amongst the "rays" would be triangles, squares, and diagonal lines between and among all the different "rays".

As an example, Website A is about Cats and contains 55 pages. From it's main page, it contains 110 internal links (within Website A) and 32 external links (going outside Website A). On each of it's 55 pages, it also contains internal and external links. Let's say this Website A has a good amount of traffic or uses keywords, so it appears in the top 20 entries of Google Search for "cats".

Looking at the main page with 32 external links (going outside Website A), we (or a web-bot spider) can follow each of these links to see where it goes. Let's say 2 links go to individual friends' sites; 6 links go to major Cat Food companies and their websites have information how-to pages; and the rest go to single pages on let's say Wikipedia, Answers.com, WikiAnswers, Encyclopedia Britannica, and other sites that have entries about the subject of cats.

Web spiders crawl each link to where it ends. This creates the "rays" in our drawing.

But webs also have internal links. So this website about cats may link from it's main page to a page on "characteristics of cats"; "types of cats"; "breeds of cats"; "cat vocalizations"; "cat products"; "cat books" etc. Each of these pages is it's own entry point into the entire website (so it's a "ray"). But, these pages can criss-cross to each other (one or several) as well as link to outside sites. This criss-crossing is what makes the other shapes that we could superimpose on top of the "rays" in our drawing.

In many ways, web indexing can be compared to using paper to brainstorm with the main topic in the center of your paper. Under one topic, you could write bunches of words or phrases all over the page (not on lines, neatly - instead, just anywhere). If you drew lines from each thing you wrote back to the center of the paper, they could overlap (superimpose) or go directly back to the center. Now, let's say on this that 9 of your classmates also did a brainstorming paper and drew their lines back to the centers of their papers. If you then took all 10 of your papers and tried to "link" one or more lines, in a logical way, your papers could all overlap.

In addition, just as Website A might link externally to Website B, there might be a Website K and a Website W that link backto Website A. So every website has what it links to, plus websites that link to it. This would also be as though 10 more students had brainstormed on separate papers and then tried to logically link onto the 10 original students we described above.

Search engines on the Internet take the hodgepodge of millions of different websites and the "links" through the TOPIC (the keywords). When you search for "breeds of cats", the search engines show you those results-- it wouldn't show you "breeds of zebras" (unless a cat page mentions zebras!). But what you don't see is how one website links to the next, because web content is kept in folders. You'd need to look at the URLs to see the folders and make an outline to really understand how one website is put together. Additionally, you'd need to list all the external links.... then, go to those sites to do more outlines of those sites, showing how they also link into the first site.

New webmasters should, in fact, draw or outline their site before starting to make webpages. This helps to visualize how each webpage will link to another webpage, and so on, and helps to organize the content and the website.

For example, if you wrote "What is Einstein's theory of relativity?"

Bing:

Result 1:

-

Google:

Result 2: 2. Physics. a theory, formulated essentially by Albert Einstein, that all motion must be defined relative to a frame of reference and that space and time are relative, rather than absolute concepts: it consists of two principal parts.

OLD/Invalid Answer:

Bing is much worse than Google, because if you type something specific in it comes up with results that are mostly nonsense and off-topic. For example, if you wrote "What is Einstein's theory of relativity?" The first result would be... "Get great discounts on Einsteins theory of relativity!" and the rest would be equally obnoxious.
