Reports can easily be deleted via the 'SEO Tools' tab on the top menu of the account dashboard, as shown below by the red box.
Here's our step-by-step guide:
1. Click the ‘SEO Tools’ tab and select the relevant tool, then click 'View Report'.
2. From the list of reports, select the one you wish to delete. Click the down arrow at the side of the green 'View Report' button (shown below within the top red box), then click 'Delete Report'.
3. Confirm that you wish to delete the report by typing 'DELETE' into the text field. Once this is done, you may click the red ‘Delete’ button to perform the action.
Please note: Once a report has been deleted, it cannot be retrieved, and all history associated with that report is also deleted, including the data.
