I would like to Know if Amazon Thinks to create for us hidden keyword slots because as are now things so many people are encouraged to not use their brain and only past and copy other designs, keywords, descriptions. Specially not MBA sellers have too advantage on this. If someone is not able, could be good not encourage him to think it's easy to make money using the work of others.
I've heard this is the case with Sellers Central but yes they don't exist here. But if you strategically work on your titles and bullet points, you can achieve fairly good results. One does not absolutely need to have hidden keywords. To give an example, in many niches I saw and a recent one of Valentines Day and more recent one of St. Patrick's Day, majority of t-shirts that were ranking for those search terms were of Merch program.
