Every website should have a content strategy focused around your top keywords. When you create content such as blog posts, videos, whitepapers, research reports and webinars, it gives people something to link to. In addition, the content you create can rank by itself in the search engines. For example, if you write a blog post on “How to Pick an SEO Company,” there is a possibility it will rank for some of the keywords you use in the title and in the body post, especially if the post gets linked to from other websites or shared a lot on social media. It also helps if your website as a whole already has significant high-quality links. 
If you are using Responsive Web Design, use meta name="viewport" tag to tell the browser how to adjust the content. If you use Dynamic Serving, use the Vary HTTP header to signal your changes depending on the user-agent. If you are using separate URLs, signal the relationship between two URLs by tag with rel="canonical" and rel="alternate" elements.
