Does anyone know if I can use Amazon Reviews for products that I put on Amazon? I "own" the listing on Amazon because we are the exclusive manufacturers of this product so the review is only referring to products that were sold through our company. Thanks,

Does anyone know more information about this directory? Is it a good quality directory that I should pay to get listed on?

I am trying to rank for the keyword "trash bags" I did  a lot of on-page optimization and link building. We started ranking #2 on bing and yahoo but google seems to be stubbornly fluctuating between being as high as 20 and as low as 45 and even dropped our rankings for a couple of weeks. Is there any need for concern if google is acting so different from bing/yahoo?

I found many duplicate title tags and I'm in the process of changing it  Do I need 301 redirects in place when I switch it? I am only changing the title tag. Also, we are switching over to a new site very soon, I am worried that we might be using too many 301 redirect "hops" because we are doing a lot of optimization as well. (video from matt cutts describing 301 redirects and hops: http://www.youtube.com/watch?v=r1lVPrYoBkA. Does anyone have any experience in doing too many redirect hops that it affected your rankings? Any good ideas to avoid this?
