The link on your Pinterest page is a do-follow link which will benefit SEO. However, the links on pins that you post and re-pin are no-follow so will not affect SEO.

In regards to best tips: what you have at the moment is great! I like the themes you have going. It would be great to see past events that you have put on. You can also use it yourselves for inspirations. This may also interest and inspire your clients/potential clients too.
