How to find Google Place ID
Search for your business on Google.
Inspect the “Write a Review” button. To do this in Firefox, right-click and choose “Inspect Element“. In Chrome, right-click and choose “Inspect“. (Most browsers follow a similar process.)
Find “data-pid” as shown above. (This part is a little tricky, but just look inside the <a> tag until you find data-pid=).
Copy the characters within the quotes (as shown above). You now have your google Places ID. Paste this somewhere you can easily find it.
