As per your statement “After a few weeks on Amazon, my product listings don’t have any organic traffics.” & “I try so hard to optimize my product listing.”, I can assume that you saw no organic sales since the beginning, and your product listings are optimized completely, you may have really good keywords, and you can check fewer competition keywords and try ranking on those, but my main point will be that check and analyze the competition, if the competition is high, and you’re not even managing any organic ranks or indexing then possibly that can be the reason, if your ranks are at 7 pages or so on so forth, then getting organic sales will be almost impossible, generally at 1st or 2nd page you can manage organic sales, sometimes 3rd page will get you sales as well, just check that what is your current standing? then maybe increase PPC to maintain higher sales to get a better ranking and eventually you’ll have organic sales.
