Thanks for your replies!

Vadim, what I mean is I get a feed of the products listed on a particular shop. I display their data "as is" which means whatever they name their product on their store is how it appears as mine, in a list with all the other merchants. I have since taken this off as mentioned

For example, previously, if I was comparing prices for a Sony Z1 Camera my product page would look like

Amazon Buy Sony Z1 Camera $19.99

CameraCentral.com Sony Camera $22.99

Camera.com Z1 Sony Camera $40.11

CameraOnline.com Buy Sony Z1 Camera $55

etc

I removed the product name column in case it was key word stuffing!

Thanks again

I run a price comparison website for a small niche at http://cdkeyprices.com

I am targeting keywords for the specific products I am comparing the price/merchants on. On a typical page I would have a price column, product name, the merchant and a buy button. Buy button is affiliate linked to the merchant.

The product name in the product column is the name from the actual website I am tracking. As such, my keyword was appearing sometimes up the 30 times.

I've took it down some months ago but was wondering if this was a bad move. I was concerned Google would think I was stuffing the keyword. I've only just gotten into SEO the past few months so was not able to  see any changes.

Should i put the product column back up or would it be considered over optimization?
