Do you mean best practices for on-page seo? If so, then you make sure your keyword/keyword phrase appears in about 5% of the copy of the page (more and Google will think it is being stuffed, less and it won't rank). Use your keyword/keyword phrase in the title, preferably at the beginning. Keep your titles to a range of 40-65 characters. Use your keywords early in the first paragraph in the last paragraph. Make sure your page has only one <h1> tag. Make sure your title and description meta tags are present and unique from other other pages on your site. Consider adding Dublin Core metadata, Open Graph metadata, and Twitter Cards metadata to help with the semantic web and social sharing.
