Beside using some techniques like SEO or SEM, you should list your website hyperlink in some articles. For example, you can create an account on Medium which is a website you can create your own blogs. Then write blogs related to your business as well as your company introduction. Remember to use key words to help customers easily find you.
Moreover, I think you should create your own community like on Facebook or Telegram or even Youtube, to interact with your users.
Hope this would be useful for you.
Lol isn't writing a blog and adding links to the text is the definition of SEO?
Just keep in mind that using websites like Medium or any open platform really won't give much weight to your links because so many other outbound links are already there.
In fact, unless your posts become really popular your links will probably be classified as no-follow which won't give you anything at all. So, back to the same conclusion content is king.
