A search engine is a very large directory which stores millions of websites. Each search engine uses a different algorithym to depict where abouts a website should appear the in the Search Engine Results Pages (SERPS) for any given phrase entered to the search engine.

A directory is a search tool much like a search engine but with a few major differences. Directories tend to employ human editors to review and rank websites submitted to their database. Yahoo! is the most well known example of a directory. Most directories catalog websites based on a variety of topic categories such as Business and Economics, or Arts and Culture. Most directories demand payment before assigning a website review to one of their editors.

All our websites are created with search engines in mind and the website design is compliant with search engine guidelines. It is a good idea for your website to be re-evaluated in time as over a period of time the search engines do alter their rules and algorithms and you will want to be certain that your website is kept up to date and complies with new rules etc.

The "Title" of a web site is probably the single most important element for natural search engine positioning. The Title is placed within the "head" of the html, is generally 12-15 words long and should be descriptive in nature.

Keywords are the most vital part of your website as they are the basis for the search engine and the users to understand the products and services offered by the website. For more details see SEO toolsunder Keyword Suggestion Tools (12)

The "Description" of your web site also resides within the "head" of your html and is usually a sentence or two containing approximately 15 words which best describe your web site.

META Tags are HTML codes (Website programming language) that allow you to describe your website to automated search engine spiders that periodically visit your website looking for changes or new information. Common META tags include TITLE, DESCRIPTION and KEYWORD tags. The TITLE and DESCRIPTION tags are most often used by the search engine to describe your website to search engine users. The KEYWORD tag is used to associate your website with specific search terms on the search engines. While this tag used to be very important, the top search engines either ignore this tag or give it very little weight when determining your search engine ranking. Their secondary purpose is to lead your visitor into your main website. For more details see SEO toolsunder Web Site Optimization Tools (13)

Google, Yahoo, and MSN have all agreed to support one method of submitting a site's pages: through an XML map placed on the root of a website. Search engine sitemaps provide a quick and easy road map for crawlers to follow in order to locate and index each of the pages on your site.

A robots.txt file is a short text file that resides in your home directory. Before search engines spider your site, they look into this file to see which files/file types and/or directories they are not allowed to see. This tool will make your robots.txt file. As a little 'extra' it also includes a block to many unwanted spiders that only crawl your site in order to collect the email addresses stored on your pages.(SPAM-bots) For more details see SEO toolsunder Robots.txt Tools (2)

To assure your website gets listed to major search engines, you can submit your website to them. Some search engines like Yahoo, charge for website submission fees, but most usually don't. Here are some major search engine submission pages.

Even after submitting your website, your site still isn't guaranteed to be highly ranked in a search. In order to help boost your site's ranking, you should optimize your web pages for search engines.

You should also consider search engine optimization before designing your homepage, in order to make both an attractive and readable website for potential clients and search engines. By optimizing your website, you increase the chances of having your site ranked in the first couple of pages. Check out 31 Ways to Promote Your Website for easy SEO.

For the same reason you need a card catalogue in a library. There is lots of great and useful information in a library, but it's physically impossible to examine all the books personally. Not even the most indefatigable web-surfer could hyperlink to all the documents in the aptly named World Wide Web. There are billions of pages on the Web. And every minute of the day, folks are posting more. The search engines and directories help you sift through all those 1's and 0's to find the specific information you need.

They'd all like you to believe they're either "the biggest" or, if they can't possibly claim that, "the best."

Google currently claims to index over 3.3 billion pages, while Alltheweb.com (one of Yahoo?s many search properties) claims to index over 3.1 billion. Search engines which demand that site owners pay to have their sites indexed, such as AskJeeves, index fewer pages.

There is less difference now than there used to be, because many search engines, including Google, have built large subject catalogues to help you search.
But think of a Web directory as a subject catalogue--something like the subject catalogue in your local library. Yahoo started out as a directory but is now de-emphasizing that aspect of their broadly-based business.

However, directories such as The Open Directory aka dmoz and the Google Directory attempt to organize Web by dividing it into topics and subtopics. Some examples include: Arts, Science, Health, Business, News, Entertainment. If you're looking for information on the Web that fits neatly into an obvious subject or category, go first to a web directory.

Think of a Web search engine as an index that enables you to seek out specific words and phrases. With the search engine's help, you can locate individual appearances of such words in documents all over the Web.

This can be both a blessing and a curse--but it's more commonly the latter! You are likely to get far too many hits. Or you might discover that your keyword has meanings you didn't anticipate. Rarely, you might get no hits at all.

In brief, here's a quick run-down of some well-known general topic search engines:

Yahoo's directory, the Google Directory, and the Open Directory Project (dmoz) are web directories -- essentially subject indices. They began as attempts to catalogue important/useful pages on the Web. Search on a subject or topic. If you know exactly what subject you're searching for, and have a good sense of how to find your subject within a hierarchies of larger subjects, a directory is a good place to start.

Google was one of the newer search engines, but it rapidly become the favorite. In fact, the word is commonly used as a verb, a synonym for searching: "I'm going to google the web to find the info I need."

Google is thorough and fast. Its technologynology considers pages that are linked from many other sites to be more important than pages that only have a few links from other sites. In other words, if many webmasters consider a website valuable enough to create a link to it, Google considers that a good reason to justsify a high ranking for that site.

Confusingly, while Yahoo's search functionality was for a couple of years been based on Google. In fact, Yahoo was one of Google's investors. As of March, 2004, however, that partnership ended, and Yahoo is now developing their own search technologynology, which will probably be based on search algorithms they obtained when they acquired Inktomi.

Meanwhile, Microsoft's search and MSN.com have also been based on Inktomi's technologynology. (Inktomi provided the technologynology for one of the hot search engines of the 1990s, Hotbot. For more info on 1990s search engines, see our historical information page for more details). Microsoft reports that it is working to develop its own inhouse search technologynology to replace Inktomi, but there is no fixed date for the cutover.

Alltheweb is also one of the newer search engines. It claims to be faster and more efficient than other search engines, with the largest index and the most rapid look-up times.Alltheweb has been acquired by Yahoo, and may at some point be integrated with Inktomi.

AltaVista was the favorite of web searchers a few years ago, but Google blew it out of the water. It still provides users with excellent search refinement capabilities, though. Altavista has also been acquired by Yahoo.

Lycos was one of the original Web search engines, but has morphed into a general web portal with something of a European focus (it was bought by a Spanish company now called Terra/Lycos).Its actual search results are based on the Inktomi engine.

HotBot, as noted above, was the original Inktomi-based search engine, but has largely faded into somewhat unjustified obscurity. It was at one time rated fastest and most accurate product for business and professional purposes, and still is a good alternative to the more popular engines if you are trying to track down information about a specific person.

Excite was a concept-based search engine. We wrote quite a bit about this concept when web search was in its infancy. It was an interesting idea, but concept-oriented search is now web history. Excite.com still maintains a website and a directory, though.
