It's a good idea to use variations as well to give your site further credibility and increase the Long Tail.
SEO Tip # 4:
SEO Fact : Content is king. Always will be. Don't assume that more is better in terms of keywords. Do not fall victim to the temptation to simply keyword stuff your site otherwise two things will happen. First, you'll get banned by the search engines and even worse, you'll be ignored by the humans who land on your page. Both types of visitors can see through vain SEO attempts to trick you to get onto their site.
Instead, you want to target the fine line between having enough keyword relevancy to make it impossible for the search engines to ignore you but not so much that your human visitors find your content to be poor quality. Hire a professional SEO article writer if you have to in order to come across as professional. Keep fresh content on your pages and change your content regularly. You don't have to waste what you've put effort and money into, instead move your old content into archives so it continues to work for you as well.
