Now some other things you can do to optimize you article.

- You should make sure to have an image or a video in the article (better both). In this case Google thinks that your article is more interesting and more valuable to people than only plain text.

- Make sure to link out to at least one relevant page (for example implement a link that goes to Wikipedia). That shows Google that you link to relevant stuff and that it should be a "serious" article.

- This is optional but I recommend it: Link to another page of your site, to another related post.

- This is something that I noticed recently. I can't tell you if this is 100% true, but it did make a difference: comments. Make sure that some people comment on your post and answer them. First it shows Google that people engage on your site and second you can use alternations of you keyword in the comments, so that Google sees better what the sites about.

We are not done!

There is something else you should do, after writing an article. On the next page you will find the first step of OFF page SEO.
