If i listed all my products in all of the free shopping cart comparison websites would my google search ranking drop? I want more traffic but I don't want to risk my google rank dropping. Thanks in advance.
oh ok what is over optimization? + if i just did it for the top 10 free shopping comparison websites be bad or good?
It shouldn't have any effect on your ranking. The one area you can get in trouble is if you use the same description on your website as all of the comparison sites. I've personally seen sites get hit with dup content penalties. The site's ranking typically returned in a week or two once the duplicate content was corrected. Make absolutely certain your product descriptions on your site are somehow different from the ones you submit to the comparison sites.
Google is looking for links back to your site from quality sources. I dont know that it will hurt you, but it may also not help a ton.
oh Awesome from the comments posted here it seems that it doesn't really matter to google. I'm not sure how much traffic it will get me but I will probably do it anyway. I need all the traffic I can get.
