I have devised a list of 3
1. Don’t use the same Title Tag for all Page titles. Instead, use various and differing keywords in your page titles. By doing this, you can make your pages more specific and this can then improve your chance of getting listed in the search engines by using more than just the one set of keywords for your site.
2. Don’t overdo the keywords in your content. You must remember to use your keywords within the content, in the body text and in the ALT tags of any images on your pages. Just be careful to not overuse them as you can then get into trouble with the search engines.
3. Don’t forget you’re targeting real people. Remember that its not just search engines that will be reading your page content of your website. Your website is mainly for real human beings that are searching and must therefore be aimed to them with interesting, up to date and relevant information that uses the keywords without any effort in the wording on your site.
