Hey Sanjay!
All keywords should be manageable within Add & Manage regardless of how they were submitted. All you should have to do is select the keyword and then click on the delete button on the top right-hand side of the page. If you're having trouble here, I'd recommend reaching out to our Help team to take a look either via the chat button on the bottom right-hand side of the page or directly via email.
Hope this helps!


Unlike our campaigns, Rank Tracker doesn't include any subdomains if you type in a root domain and choose the 'Entire Subdomain" radial.
