It is entirely up to you if you'd like to use RevenueWell's web links or website widgets. They are simply tools for you to use to help your patients request appointments, get to their patient portal, and view your wonderful reviews.
Every email that RevenueWell sends out already has the link for your Patient Connect Portal as well as a button to request an appointment. If you wish to draw more attention to your portal, or run a campaign directing patients to it, then you can use the web link for that purpose.
As for your website, you'll want to discuss with your web developer the best way to draw patients' attention to the areas they are looking for. For instance, it can be a good idea to include the widget on a certain page as well as links for the Request an Appointment page elsewhere.
