I have a question about optimizing back end keywords:
I have just found out how to check whether or not Amazon has indexed the back-end keywords for my product. I now have a list of all the keywords that were not indexed. I seem to be getting mixed information on what to do now.
Do I delete the non-indexed keywords?
Do the non-indexed keywords cause worse ranking on my indexed keywords?
Is there a way to get the non-indexed keywords indexed?
