Welcome to the Q&A Forum

There was actually a pretty solid Whiteboard Friday covering a similar topic. The Googles are only 'pretty good' at figuring out which page is the original, and which site should be given better placement for the same content. So you're not being silly for being concerned. Panda. I honestly think you'll find something you can use in the video, so I won't get too carried away on that subject. Your next problem is buy-in. Will your client do what needs to be done? To get the sale you have to sell. Present it as something that hurts resellers as well as the client. Which it likely is, or will, hurt both in a material way. If the resellers aren't being seen well enough due to the duplicate content issue, your client is losing on sales. The reseller is directly losing potential revenue. So whatever you put together out of this, the wise will heed your words - as they're losing money.
