Steps
Open your profile
On a computer or phone, search Google for your business name while signed in. Your profile opens with its own editing buttons above the results. In the Google Maps app, tap Business at the bottom right instead.
Open Bookings
On Search, select Bookings. In the Maps app, tap Edit profile, then Bookings. Some categories show Food ordering or Pickup and delivery in its place.
Select Add link
Select Add link. If a link is already there, from you or from a booking partner, select Add another link.
Paste your booking page
Paste the address of the page where customers book, not your home page, so the Book button opens the booking form straight away.
Set the preferred link
If there is more than one link, select Set preferred link and choose yours, so it is the one customers see first. Google allows up to 10 links for each kind of action.
Save and test the button
Select Save. A little later, search for your business again and select Book to check it opens your page.
If you do not see it
- No Bookings button. Google offers booking links only for some business categories and regions. Check that your primary category describes what you do, in Edit profile.
- A profile not yet verified. Verify the profile first. Google lets some businesses change their details only after verification.
- A link you never added. Booking partners can add links of their own. On Search select Bookings, then Remove Provider; Google says a partner must remove its link within 5 days of the request.
What Fly does here
Fly asks before replacing a link
For a business that takes appointments, Fly makes a booking page on your Fly website where customers pick a free time from your opening hours, and offers to put it behind the Book button on Google; on Fly does it all it adds it on its own. If a link of yours is already there, such as Practo or Calendly, Fly asks once, on every mode, whether to swap it, and keeps yours if you say no. Read what else Fly does on the GBP Growth Agent page.
14 days free on one location, no card. Then Rs 2,499 plus 18% GST or $24.99 a location a month.
Questions
How do I add a "book now" button to my Google Business Profile?
Add a booking link. Open your profile on Google Search, select Bookings, then Add link, paste the address of your booking page and select Save. Google shows it as the Book button on your profile.
Does Google have a booking feature?
Google shows a Book button on profiles in some categories. It opens the booking link you add, or one from a Google booking partner. You choose the preferred link, and you can remove a partner from Bookings.
How do I get a URL link for my business?
Your booking link is the address of the page where customers book: your booking software, a form on your website, or a booking page from a service you use. Open that page, copy the address from the browser bar and paste it into Bookings on your profile.
