The content placed on web pages and websites is unlike any other content in the world. Serving a dual purpose, online content is there for (1) the visitors to a website to find the information they were searching for in the first place and (2) to up the web page or website rankings within the search engine results. This dual purpose requires a special style of writing known as Search Engine Optimization or SEO.

SEO, or search engine optimization, is just what it sounds like. Optimizing the content placed online in order to be viewed in a friendlier, search engine manner. To better understand SEO, one must take a closer look at how the pages of a website are indexed by these search engines.

Web crawlers or robots surf the Internet just as a person would search. They look for websites that are frequently updated with new content first and then trickle down through the Internet reading and indexing the pages of many websites. When the robot reads a specific page, it checks all of the words on that page. Focus remains on the beginning of the page and the end of the page with a quick skim through the middle portions of the content. What the robot is looking for is repetition. Repeating words are at the heart of SEO.

A keyword or a keyphrase that represents the website needs to be placed repeatedly throughout the websites words, articles, meta tags and descriptions. These words are the ones that the robots will pick up on and the basis of SEO. The more the words are "read" the higher the page will appear on search engine rankings.

This may seem like a very easy task to accomplish. Why not just fill an entire page with the same keywords over and over again. Well, according to most search engine robots, content with too high a percentage of keywords can be considered an attempt to manipulate your positioning and red flagged as SPAM. Not a good thing for the web page or website. So how much is enough?

Generally speaking, web content needs to have a keyword density, the number of keywords placed within a written article or piece of writing, ranging from 2 percent to 5 percent. These keywords need to be placed within the wording in a natural manner, while maintaining the informative nature of the article or writing piece.

SEO is an art; there are more rules, tricks and tips to this art than any other on the Internet. One can be sure that everyone who knows about SEO tactics and search engines also know that everyone is trying to optimize their website, which in turn makes the battle fiercer than ever. The more pages on your site with a 2 percent to 5 percent keyword density, the better you will rank with those robots.

Learning how to write SEO content for the web takes time and practice. In order to speed up the process, there are many SEO writers available to outsource any and all web content projects you may have. These outsourced writers are trained in SEO and can provide that perfect keyword density every time.

So whether you decide to outsource to optimize your website or give it a go on your own and learn all about SEO and search engine rankings, this is definitely a strategy that is well worth the efforts and/or cost and will reap you benefits for the duration of your website.
