I am curious as to your priorities, in order to get more traffic from organic listing at engines?
The only SEO I go out of the way to do is the improve my meta titles and descriptions, making them more clickable at engines. Every other SEO thing, like unique content, responsive design, etc. have already been done, or are already written in my checklist and easy to do when giving effort to do them.
Once my meta tags are done, I will make creative writing the priority. I will spend half my time coming up with the right words for the descriptive titles.
