You can add links, or even just random info, which appear as a table next to your public profile.
1. Click on "Edit Profile"
2. Go to "Profile Metadata" section and fill in one or more rows
3. (optional) To verify your ownership of a website, insert the verification code into your website's code. This will make verified links turn green on your profile with a tick next to them.
