Good SEO content has three primary characteristics

What is good content? find the answer you want your site must deliver value to its visitors and do it in an engaging way. Few sites specialize in a subject so narrow that they have an information niche all to themselves. You'll have competition. Set yourself apart from it with expert interviews, meaningful lists and well-researched resources. Write well or invest in someone who does; your investment will pay off in increased traffic. 

 Although search engines aren't your primary audience, they still influence your page rankings. In the days of early SEO, using keyword-stuffed META tags brought in plenty of traffic. People didn't hang around on a site that promised low air fares and delivered advertisements, but that didn't affect the search engines. Each iteration of the engines' algorithms got better at discerning valuable sites from clutter, though, so site creators had to sharpen their technique as well. Instead of META tags, they used keywords sprinkled throughout an article.

Keywords in URLs and File Names

The Web site name and the whole URL of a site tell a lot about it. The presumption is that if your site is about Mysterious, you will have “Mysterious” as part of your domain name. For instance, if your site is mainly about adopting Mysterious, it is much better to name your Mysteriousal site “Mysteriousall.com” than “Mysteriousworld.com”, for example, because in the first case you have two major keywords in the URL, while in the second one you have no more than one potential minor keyword. 

Keywords in Special Places in the URL

Keywords are very important not only as quantity but as quality as well – i.e. if you have more keywords in the page title, the headings, the first paragraphs – this counts more that if you have many keywords at the bottom of the page.

The reason is that the URL (and especially the domain name), file names and directory names, the page title, the headings for the separate sections are more important than ordinary text on the page and therefore, all equal, if you have the same keyword density as your competitors but you have keywords in the URL, this will boost your ranking incredibly, especially with Yahoo!.

The Keyword Density Checker

After you have chosen the keywords that describe your site and are supposedly of interest to your users, the next step is to make your site keyword-rich and to have good keyword density for your target keywords. Keyword density although no longer a very important factor in SEO is a common measure of how relevant a page is. 

Generally, the idea is that the higher the keyword density, the more relevant to the search string a page is. The recommended density is 3-7% for the major 2 or 3 keywords and 1-2% for minor keywords. Try the Keyword Density Checker below to determine the keyword density of your website.

Select the Right Keywords to Optimization

A one-word search string is centuries ago. Now, when the Web is so densely populated with sites, it is next to impossible to achieve constant top ratings for a one-word search string. Achieving constant top ratings for two-word or three-word search strings is a more realistic goal.

 For instance, If you have a site about dogs, do NOT try and optimize for the keyword "dog" or "dogs". Instead you could try and focus on keywords like "dog obedience training", "small dog breeds", "homemade dog food", "dog food recipes" etc. Success for very popular one-two word keywords is very difficult and often not worth the trouble, it's best to focus on less competitive highly specific keywords.

Keywords – the Most Important Item in SEO element

Keywords are the most important SEO element for every search engine, they are what search strings are matched against. Choosing the right keywords to optimize for is thus the first and most crucial step to a successful SEO campaign. If you fail on this very first step, the road ahead is very bumpy and most likely you will only waste your time and money. 

There are many ways to determine which keywords to optimize for and usually the final list of them is made after a careful analysis of what the online population is searching for, which keywords have your competitors chosen and above all - which are the keywords that you feel describe your site best.
