For adding a Google review direct link to business
Google Place ID Lookup:
Go to the Google Place ID Lookup Tool.
Enter your business name in the search box.
Click on your business name from the dropdown results. You’ll see a map pinpointing your business location, and below it, there will be a long string of numbers and letters. This is your “Place ID.”
Create the Review Link:
Once you have the Place ID, append it to the end of this URL: https://search.google.com/local/writereview?placeid=
For example, if your Place ID is ChIJN1t_tDeuEmsRUsoyG83frY4, your review link will be: https://search.google.com/local/writereview?placeid=ChIJN1t_tDeuEmsRUsoyG83frY4
Paste the Link on Your Website:
Now you can use this link on your website to direct users straight to the review writing section for your business on Google.
