1.- Putting Keywords in Titles:
A really important thing is to put keywords in titles, how is that? simple, add between the < title > and < /title > tags the keyword you want to rank for. For example this article's title would be On page SEO.

2.- Putting keywords in url:
Another thing to do is adding your keywords in your url, For example, here we want to rank for On page seo, so our URL should be on-page-seo.html, we used dashes cause searche engines read dashes (-) as spaces.

3.- Putting keywords in Tags:
You also should add between the and tags the following code:
< meta name=“keywords" content=“your, keywords">
< meta name=“description" content=“Your site description including your keywords“>
Obviously replacing it with your own content.

4.- Putting image descriptions on alt tags:
Remember to put descriptions on your images using the alt tag.

5.- Use Heading Tags:
Use heading tags in your main keywords, H1 for your main keywords, H2 for your secondary keywords and h3,h4,h5,h6 for the others.

Well, that are the main things to do, if you do all that you should have a site ranking well.
