I am wanting to place some items up for sale on one of my sites, these items are from Amazon.

Here is my question? There is only so much you can say about some items. I know that copy and paste the Amazon descriptions is not a good idea. With all these updates from Google anyone have a good formula on how many words are needed or what should be done/said?

My guess is that saying the item is Green Felt and Sizes are S, M, L along with a pic, will not be enough to rank in a google search.

Thanks in advance.
