You can take multiple steps to improve your listings:
Amazon identifies listings that need improvements and provides recommendations on which product attributes you should provide. To view listings that have listing quality opportunities, go to the Inventory menu and select Manage All Inventory.
To see the detail of the opportunities, in the Listing Status dropdown, click Improve listing quality. For each listing, you can click on the issue to view a brief description of the attribute to be filled-in in the side panel. After you have made changes and filled in the missing attributes, click Save changes. Changes will take up to 48 hours to reflect.
Once you have addressed the opportunities, if you have additional ones, they will show up on the list. We recommend that you review these opportunities on a weekly basis.
To reject an opportunity you find irrelevant, click … and select one of the reasons. The opportunity will disappear in 48 hours.
