Because eBay is flagging users who have multiple items with the same title we have developed a tool to find out if you have multiple titles under different SKUs. Just go to Inventory > Duplicate Title Scan.
On that page you will see 'The following items have duplicate titles across listings. Note: This list is ONLY items set to list to ebay, i.e. items without the 'Do Not List on ... eBay' flag off.
To the best of our knowledge eBay will be satisfied if you change something titled "The Best of ... " to "The Best of ... Joe's Funky Music".
