In order to promote your website using SEO, I think at first you need to learn from many famous and largest websites about SEO such as: searchengineland, searchenginewatch, searchenginejournal, Moz,...they're all giving free basic SEO techniques that you can follow and practice. After that, you should apply these techniques on your own website with your domain and hosting, try your best to practical daily as much as possible.
I believe that you can get the archive after some months you try hard.
Good luck to you,
