Our Process

Triple Optimized Amazon Listing Methodology

Triple Optimized Amazon Listing

Our unique process to reliably maximize click through and conversion rates on Amazon. Developed from experience creating 1800+ Amazon listings since 2016. Utilized in every service offered by Kenji ROI.

Key Info Optimization: We identify crucial buyer language, benefits, & selling triggers your customers subconsciously scan for, & place them in the most prominent places in the listing.

Keyword Optimization: Identifying which keyword phrases are most relevant with high traffic and not too competitive, then placing them throughout the listing to optimize for Amazon keyword ranking.

Persuasive Desire Optimization: To buy anything customers must have a pain, believe your product will solve their pain, & their desire to remove pain is greater than the cost of your product.

About Kenji ROI

Amazon listing optimization services by experienced sellers since 2016.

Kenji is the middle name of our CEO Danny Carlson, 7 figure ecommerce entrepreneur & host of the Actualize Freedom Podcast. Built from a personal need, Kenji ROI expanded quickly after acquiring some high profile clients like Kevin David, Tom Bilyeu from Impact Theory, & Oddbods (Disney Channel show).

We are a mostly remote company with Danny (Canadian) living in Bali along with the photography & video teams. Says the Creative Director in Singapore, Minh the Director of Amazon Ads in Vancouver, and the graphics team in the Philippines. We embrace the “digital nomad” lifestyle that many of our clients also enjoy.
