I read duplicate content is bad. However I also read that google can not pin-point where the original content came from so it is hard for them to just rank one site poorly because of duplicate content in fear it could be the original site.
Currently our original product site ranks better in Google. However, we are using the "manufacturer info" website as our "brand" now days. I want it to rank organically. Currently we get 90% of our traffic from Adwords spend. I would like to change this. Neither one of our websites are ranking as well as the competition lately.
We are well known in the industry but yet we rank the worst in Google.
What should I do to improve the ranking? Each product has around 100 words for a description. We have a site index. The domain is not new and has been around for 7 years.
