Most of the authority as to what terms are important to your site come not from what you say on your website pages, but what other web sites say round you. And this is by how they link to you.
Each link has what is often known as an anchor text - this is the piece of text that the reader will click on to use the link. But the search engines take a look at this anchor and use it as a vote for the site. So, if the anchor text is "search engine hints" then you have 1 vote for that term pointing to your website. Get sufficient votes and you will be top of the list.
Historically, website owners have done this by running link exchange sites on their sites. Mass exchanges, where you link to another web site in return for them linking to you. This was fine, but as with the content issue, everything to optimse a web site needs to shout out 'natural'. Search engines can straightforwardly spot huge sites and most have no page rank and are useless.
So, we need a way of link building that gives natural links, ideally from web sites that we are not enforced to link to in order to keep the link back in place. And the remedy to this is article writing. I'll look at how and the other reasons later in the article.
So filling meta data and tags with keywords is old hat and link directories are out of the window because they have no value. But we need links and to do that we write articles. But, what is so good about article writing? Article writing beyond doubt does get web-sites to the top of search engine rankings, but that is only one part of the story.
For lots of websites, there is a market of potential consumers that spread far and wide and some of these are researching more information by reading article directories. Others might be looking for products and services and will stumble onto articles on directories.
Either group, if interested in the article, might then see the author's biography at the end of the article and then visit the author's site. With one recent brand new site, before it had even been cached by the search engines, I was able to get it up to 40 new unique visitors per day, only through people reading a handful of articles on 1 top article directory.
Also, given that a major grounds for writing articles is the search engine assistance, the plusses go on. Not just does the article get printed on the directory that you submit it to, but other sites and websites will pick up the article, print it and link back to you.
So, we write articles for 2 reasons. First they are tremendous with the search engines and boost our ranking position and second people will read them on the web-sites we submit them to and visit our sites. But how do we write them?
