Don't pay for review sites - you will be paying to build their brand.

 

You need to control as much of your practice as possible and if you pay for review sites such as Trustpilot, Doctify or RealSelf, you will be helping to build their brand, not yours.

 

When people search for you, they will be directed to these sites, and unless you opt for premium subscriptions, they may be diverted away to one of your competitors.

 

...and when you stop paying, you will not own any of the reviews.

My preference is to have a Google My Business page and encourage reviews on this.
