About Kenji ROI

With experience selling on Amazon, listing optimization services have been our specialty 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.

Amazon A+ Description

A+ Content Description

If you’re Brand Registered on Amazon, you get access to the advantageous  A+ Content Description. 

It’s an easy way to boost conversion rates by showing off key product benefits with additional pictures & graphics halfway down the listing. They almost always have a higher conversion rate than regular descriptions, & since only Brand Registered brands can use it, is an easy way to set you apart.

See our popular Amazon A+ Content Tutorial 2020 to learn more.

Product Description

In our Full Listing Copywriting package, we ensure your description is not only Amazon SEO Optimized, but easily readable with key information accessible.

Backend Search Terms

Often referred to by Amazon Sellers as “backend keywords,” this is a text field of 250 “bytes” (similar to characters) inputted when editing a listing in the Seller Central dashboard. It’s an important place for top performing relevant keywords to show Amazon’s ranking algorithm which keyword searches to show your product.

Amazon Subject Matter Fields

Subject Matter Fields

The “Subject Matter” fields are 5 fields of 50 characters each for a total of 250 characters, Their original purpose is to give Amazon a bit more context about what your product actually is, but they are powerful keyword fields!
