If you're researching diabetes and the word "diabetes" appears multiple times in a Web document, it's reasonable to assume that the document will contain useful information. Therefore, a document that repeats the word "diabetes" over and over is likely to turn up near the top of your list. If your keyword is a common one, or if it has multiple other meanings, you could end up with a lot of irrelevant hits.

And if your keyword is a subject about which you desire information, you don't need to see it repeated over and over--it's the information about that word that you're interested in, not the word itself. Some search engines consider both the frequency and the positioning of keywords to determine relevancy, reasoning that if the keywords appear early in the document, or in the headers, this increases the likelihood that the document is on target.

For example, one method is to rank hits according to how many times your keywords appear and in which fields they appear i. Another method is to determine which documents are most frequently linked to other documents on the Web. The reasoning here is that if other folks consider certain pages important, you should, too. If you use the advanced query form on AltaVista, you can assign relevance weights to your query terms before conducting a search. Although this takes some practice, it essentially allows you to have a stronger say in what results you will get back.

As far as the user is concerned, relevancy ranking is critical, and becomes more so as the sheer volume of information on the Web grows. Most of us don't have the time to sift through scores of hits to determine which hyperlinks we should actually explore.

The more clearly relevant the results are, the more we're likely to value the search engine. Information On Meta Tags. Some search engines are now indexing Web documents by the meta tags in the documents' HTML at the beginning of the document in the so-called "head" tag.

What this means is that the Web page author can have some influence over which keywords are used to index the document, and even in the description of the document that appears when it comes up as a search engine hit. This is obviously very important if you are trying to draw people to your website based on how your site ranks in search engines hit lists. There is no perfect way to ensure that you'll receive a high ranking. Even if you do get a great ranking, there's no assurance that you'll keep it for long.

For example, at one period a page from the Spider's Apprentice was the number- one-ranked result on Altavista for the phrase "how search engines work. There is a lot of conflicting information out there on meta-tagging. If you're confused it may be because different search engines look at meta tags in different ways. Some rely heavily on meta tags, others don't use them at all.

The general opinion seems to be that meta tags are less useful than they were a few years ago, largely because of the high rate of spamdexing web authors using false and misleading keywords in the meta tags. Google, currently the most popular search engine, does not index the keyword metatags. Be aware of this is you are optimizing your webpages for the Google engine.

It seems to be generally agreed that the "title" and the "description" meta tags are important to write effectively, since several major search engines use them in their indices. Use relevant keywords in your title, and vary the titles on the different pages that make up your website, in order to target as many keywords as possible. As for the "description" meta tag, some search engines will use it as their short summary of your url, so make sure your description is one that will entice surfers to your site.

The "description" meta tag is generally held to be the most valuable, and the most likely to be indexed, so pay special attention to this one. In the keyword tag, list a few synonyms for keywords, or foreign translations of keywords if you anticipate traffic from foreign surfers.

Make sure the keywords refer to, or are directly related to, the subject or material on the page. Do NOT use false or misleading keywords in an attempt to gain a higher ranking for your pages. The "keyword" meta tag has been abused by some webmasters. For example, a recent ploy has been to put such words "sex" or "mp3" into keyword meta tags, in hopes of luring searchers to one's website by using popular keywords.

The search engines are aware of such deceptive tactics, and have devised various methods to circumvent them, so be careful. Use keywords that are appropriate to your subject, and make sure they appear in the top paragraphs of actual text on your webpage. Many search engine algorithms score the words that appear towards the top of your document more highly than the words that appear towards the bottom.

It sometimes helps to give your page a file name that makes use of one of your prime keywords, and to include keywords in the "alt" image tags. One thing you should not do is use some other company's trademarks in your meta tags. I have, in fact, testified as an expert witness in such cases. You do not want the expense of being sued! Most of all the research including ours shows search engine parity with search results very similar on MSN, Yahoo and Google.

The best search engines rely very heavily on the number of text links pointing to a web site as a major factor in determining search engine rankings for important high traffic keywords. So if you think Google is the best search engine type "computers" on Google and see that Apple is number one, because of all the millions of text links pointing to Apple using the anchor text "computers". The funny part is when you click on to the Apple site, you only see ipod's.

So this focus on links can cause problems. Frankly this is a funny yet rare example as the link based algorithms are actually quite effective most of the time and Yahoo and MSN have followed Google and the PageRank technology Google developed. MSN is spending about 20X more on advertising than Google is.

I would not bet any money against Google however and the Microsoft stock price has been flat for the last 3 years. It is also the most popular search engine in the world.
