Google technology relies on "authoritative" websites to identify the authoritativeness of a website. Simply put, the more authoritative websites link to a site, the higher its authority rating will be, and the higher will it appear in the search results.

Just a link from your site will help a great deal; more so if your website is a higher-rated website itself.

If you don't have a website, just give the URL to your colleagues, students, co-teachers, etc. and let them visit the site. :)

Thank you very much.
