Most happy customers will leave a review - if someone asks while the visit is still fresh. This automation does the asking, politely, with a link straight to where your reviews live.
When it sends
A few days after a visit you've marked completed. It never follows a missed appointment, never asks the same person more than twice a year, and leaves a few days' space after any other automated note - so nobody feels bombarded.
Setting it up
It sleeps until you paste in your review link - the page where you'd like reviews to land (your Google profile is the usual choice). Add the link on the automation's card and it wakes up.
Good to know
The card's log shows every ask and whether that customer booked again afterwards - so you can see it earning its keep.
