Your Google my Business profile on Google Maps is one of the most powerful and underrated marketing tools at your disposal. Not only can you connect your website and phone number, you can also show:
Opening and closing times, including holidays
Photos and images
Reviews
Manage bookings
Create posts selling; products, services or inviting to events
You can create a link directly to a company's "write a review" section on their Google my Business page on Google Maps. To do this you will first need to establish the location's "place ID" via the Google Maps Platform linked here.
Once you have the place ID, you can add this to the end of the below link string to create a link direct to the review section:

TrustPilot will often create a business profile for you and allow your business to get reviews before you even claim your TrustPilot profile. Alternatively you can create or claim your TrustPilot profile by simply entering some contact details for a responsible person, and confirming the website and company details. To create a link to your TrustPilot profile simply change company name on the below example:
