Search Engine Optimization is not possible to cover satisfactorily on one page of a website. There are thousands of websites dedicated to telling you exactly how to improve your search engine rankings.
Your SEO goal is to have every article in the top spot on Google. There are two components to this:
- What you write in the article
- How many quality links you can get TO your article
There is a tremendous amount of garbage written by ‘gurus’ about how you should write an article. These guys have never written an article in their lives. They are just guessing.
