Does the keywords data for the Projects get updated regularly?

Yes.

The keywords and ranking data that you have in your Projects gets updated everytime your subscription is renewed. This allows you to use the most up-to-date data to decide on your contents strategy and make changes as needed.

"Every time your subscription is renewed" here refers to your subscription when it is renewed with each monthly payment.

For customers who prefer to pay by invoice (post-payment), since the contract is established at the beginning of the month, the keywords are updated once at the beginning of each month.
