Restaurants
Your reviews are on Google, Tripadvisor, OpenTable and the delivery apps. Your website shows none of them. This fixes that.
Review widgets for gyms & fitness
People join a gym on trial and decide in the first week. Reviews from members who stayed are what convince the ones who have not signed up.
The sources that matter for gyms & fitness
Customers in this industry do not all review in the same place, and the platforms are not equally worth your effort.
Where to put them on the page
On the homepage and on the membership or trial page, next to the sign-up button.
Full-width sections suit carousel and grid layouts; tight spaces suit a badge.
When to ask for a review
A few weeks in, once someone has established a habit. Asking on day two produces a review about the induction.
Google allows asking and prohibits incentives. Yelp asks you not to solicit at all. More on asking.
ClassPass members are not your members.
They churn faster and judge differently. Useful reviews, but do not read them as a measure of how your regulars feel.
Questions
Other industries
Hotels
Guests who found you on an OTA are looking at your own site to decide whether to book direct. Reviews are what close that.
Ecommerce
Reviews on a product page are the last thing between a visitor and the buy button, which is why placement matters more here than anywhere else.
Local business
Most people who find you have already looked at your Google rating. The job of your website is to confirm it rather than to introduce it.
