Hi guys. I've been reading a lot of different seller tips last couple of days and I have a few questions: 1. Some people say that product title has 500 character limit, and that seller should use it in full, stuffing it with keywords like crazy. Is that true? Does that really help? 2. There are a lot of different opinions on keyword instrument, but from what I can see the AMZShark is the one to go. Is it actually that good that people say or there are a lot better and maybe cheaper? I know that good stuff doesn't go cheap but still, as I am at the start of it I don't want to disperse funds on something I may not be needing much. 3. What should I dig deep into to make it better in amazon sales? Like what do I have to read in the first place (if there's anything good) or should I just read the actual amazon FAQ through and that would be enough? Thanx! P.S. I think I'm going to ask more as I didn't stop reading articles to get different perspectives.
