Hello,
Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.
Can you please confirm if you’ve connected your Google Account properly by following the steps mentioned here? https://rankmath.com/kb/connect-your-google-account/
If so, then the data should automatically appear in a few minutes to hours. However, if you’re still not able to see any data on your Analytics Dashboard then please try to follow the steps below and see if that works for you:
1. At first please head over to WordPress Dashboard > Rank Math > Status & Tools > Database Tools and click the Rebuild Index
button.

2. After that, Head over to WordPress Dashboard > Rank Math > General Settings > Analytics tab, click the Delete Data
button, and then click the Update Data Manually

It will start the new data fetch from Google. You can reload the page to see the notice related to the import process.
Once the process is complete. Please check the Analytics page again.
Let us know how it goes. Looking forward to helping you.
Thank you.
