You are receiving the "Keyword Limit Exceeded" error because the number of keywords in your account has reached the maximum your current subscription plan allows. To add additional keywords, you have two options:
Upgrade Your Subscription Plan: Consider upgrading to a higher tier plan that accommodates more keywords. This will enable you to track additional keywords without disrupting existing data.
Review and Remove Existing Keywords: If upgrading is not an option, you may opt to delete some of the existing keywords. Please be aware that removing keywords will permanently erase all associated tracking history from our tool.
