1. Keep it Short - Limit your article to less than 1000 words. A long paragraph without breaks is boring. Best is to put things in short points (like the one you are reading :)) else you can break the article into small units, making the articles reader friendly. If its any longer consider break it into two posts.

2. Reliable Data - Give links to authoritative domains like wikipedia when quoting facts. Don't give outbound links to spam my non authoritative sites. Mention reliable sources you used to collect the data for help visit www.greatseosecrets.com. Always give credit to original authors. In return you might even get a link back :). Check out one such article - 51 interesting facts about silver - that follows this for example.

3. Classic simple layout of content - Introduction, main content, and finally the summary. Keep it simple.

4. Choose Keywords before writing: Before you write any article think of keywords you are targeting as you write SEO friendly article (hint).

It should make a complete read for them. You will get more digs, readers, subscribers doing this.

8. Write article for readers not search engines - Don't abuse the tips in this article. Write for users not for search engines. Keep the reader engaged (I just hope you have reached till here ;))
