Hi everybody, Hope you're all doing well. At first i would like to beg pardon for my bad English. Every Amazon or other e-commence seller like to take their business next level. Like Amazon as well as other e-commence marketplace like eBay, Walmart or Etsy every seller want to promote or rank their product by using different SEO services. Now don't be imbecile by verbose word "Trade Secret White Hat Methods" until you became 100% sure about Methods, Working procedure and SA safety. Otherwise It's definitely "drinking old wine in a new label". Amazon recently changed their Search Algorithm named Amazon A10. We all know that the previous algorithm was changed based on Purchase, Reviews and giveaway. After A9 update it was totally forbidden discount reviews, fake sales for rank product etc.. Amazon became very strict about payment methods (purchase without valid payment methods like credit card, debit card or PayPal account may not allow to submit reviews and seller rated feed back) also without valid payment options endanger the seller account. So the FBM purchase was totally banned which was the main Black Hat way to rank product or keyword 1st page. Now the latest changed of Amazon Algorithm ( A10 ) is about all Black Hat methods Like Wish List, Shopping List, Gift List, Add to Card, Weeding Registry. Amazon Just want to highlight the best product on 1st page for customers base on their TOS. So you should avoid the Black Hat methods like Automated bots, click Funnel Or Unsafe impression creating system. Before using any Product / Listing / Keyword ranking services be aware about White Hat & Black Hat methods. Don't be foolish to here about "Trade Secret White hat Methods". As a seller center holder you've full right to know all working system, methods, working procedure, SA safety etc.. ins and out. There are huge guy using old unsafe working system and Black Hat methods saying that White Hat. They may not show you the methods regarding as their trade secret definitely going to flagged your seller account. By refusing to share the working system and methods claiming as trade secret, It's like selling old product on a new label. I'm not saying that WL, SL, A2C, GL is effect less or dangerous but all you need to be sure about methods and working system. Don't be influenced by word " White Hat" while Amazon doesn't support any SEO for ranking product and of course so called "Trade Secret White Hat Methods" otherwise you're going endangers your main business. So be 100% sure about what's are you going to do with your business. Until became fully clear about SA safety don't use any SEO services for your valuable Amazon business. Happy Trading. Best Wishes, Wazed A.
