Computers connected to the Internet are linked between each other. Therefore, they can offer resources using one or more protocols available.

The Internet had an impressive growth rate, which also implied an impressive growth in the resources that are available. For regular surfers, navigating and reaching the desired content became increasingly difficult.

Therefore some resources started to offer searching services. They act like gateways, and provide the surfers the ability to find fast and effective the content they desire.

The surfers usually specify their needs by typing one or several keywords, and/or selecting a specific topic to which the search will be narrowed. The output consists in a sorted list of results, which indicate towards individual resources available.

The main functions of a search gateway is to find content according to the demand of the surfers, and to sort this content before delivering it based on the relevance of each item compared to the surfers' interests.

Specific Functions

A searching gateway has two specific activities: learning and serving. Those 2 activities are performed usually both at the same time.

In order to be able to serve queries (that is, to generate replies based on user requests), a search gateway will need to have some sort of information on which to rely to. The process of accumulating, revising and improving this information is part of the learning process.

When users will make a query, the searching gateway will use the information accumulated until then in order to generate the results and to deliver them.

Why doing articles submission?

There is little doubt that doing article submission can increase traffic and improve search engine ranking.

But for now, submitting articles to a free article directory remains an excellent way to brand yourself and your website, increase the number of backlinks to your website and acquire targeted human visitors to your site.

An article directory is a website that publishes articles written by website owners and freelance writers. These articles are typically submitted via an online form and then they are queued for review by the directory editor. Articles that are well-written and follow the submission guidelines are approved and published online. The Resource Box at the bottom of the article can contain up to three hyperlinks to the author's chosen web pages. This is the most important part of the article, since this is where you can entice the reader to click on a link to your site for more information.

The keyword density in the article affects the ranking of the article in the SERPs, but the most important items in the author's resource box are the hyperlink text and the surrounding text. The text used for the hyperlink, also known as anchor text is a key factor search engines use when weighing the relevance of search results. Choose your anchor text carefully and stick to one or two of your most important keyword search phrases.

Let's say you have a blog about weight loss. You write an article about some of the most effective weight loss supplements, and then you submit it manually to five article directories. You have used the WordTracker keyword tool along with your own keyword density tools to choose two targeted search phrases: weight loss blog and diet supplements. Now you should make sure to use these as the anchor text in your resource box for this article and your following articles.

The more articles like this you submit, the better you are targeting your promotional efforts. The important thing is to choose keywords that people use to search for your products, and to be as specific as possible. Unless you have a very big budget and a lot of time to promote, it is useless to use "weight loss" as your targeted phrase. It is too general (47,400,000 results in Google) and many established competitors will be competing on this phrase. Just choose one or two somewhat specific keyword phrases and stick with them.

If your article is approved, you don't have to wait a long time to see some traffic trickle in from that article. You can secure free, oneway backlinks while providing your audience with helpful information in your article.
