Longer version is to tell them to learn as much SEO you can and try to be each time in contact to it. The world is changing and SEO is changing with the current tendencies. For example, a few years ago people have been using some tools to increase the rank of their websites and make them easier to find and that tool has become forbidden by the search engines (they were lowering the rank for those websites moving and burying them on another page in search results on or excluding completely the links from the search engines). The most important thing is to keep writing and be natural, add internal links inside the website articles or pages making some of its URLs even easier to find and try to add more natural backlinks to your website. Adding them yourself can be bad, be friend to another people and they will write more and more often about you and they will add the backlinks in their own way.
