Brand & Background

Brand & Product

NausX is a pet health brand specializing in anti-motion sickness and nausea relief tablets for dogs. Their pharmaceutical-grade OTC formula treats symptoms including vomiting, excessive drooling, whining, dizziness, and disorientation during car, plane, and boat travel. Available in formulations for small breed (under 15 lbs), medium breed (16–50 lbs), and large breed (51–90+ lbs) dogs, NausX provides fast-acting relief lasting approximately 6 hours per dose. Sold by Pharmapac on Amazon.

Objective

NausX wanted to leverage Listing Labs' expertise to break through a highly competitive pet health category dominated by big brands like Cerenia, Ark Naturals, and store-brand alternatives. The goal: improve listing visibility, optimize ad efficiency, increase conversion rates, and establish NausX as the go-to OTC motion sickness solution for pet parents on Amazon — maximizing both revenue and profitability.

The Challenges

What Was Holding NausX Back

NausX had a genuinely effective product with strong customer reviews — but their Amazon presence was underperforming due to several critical gaps:
1

High ACOS, Low Profitability

Advertising cost of sale exceeded 52% with no campaign segmentation. Most ad spend went to broad, expensive terms with poor conversion, erasing margins on every sale.

2

Unoptimized Product Listings

Titles and bullet points lacked critical search terms like "dog motion sickness medicine," "anti nausea for dogs car ride," and "dog travel sickness tablets." Backend search terms were incomplete.

3

Weak Visual Communication

Product images didn't convey the product's veterinary-grade quality, dosing simplicity, or multi-size availability. No lifestyle images showing happy dogs traveling. Low CTR compared to category leaders.

4

No A+ Content or Brand Story

The below-the-fold experience was a blank wall. No enhanced content to build trust with pet parents, explain how NausX works, or compare formulations across dog sizes.

5

Poor Cross-Sell Between Sizes

The small, medium, and large breed products operated as isolated listings. No variation structure, no comparison modules, and no advertising linking the SKUs together.

6

Competitive Pressure

Competitors like Cerenia (prescription), Ark Naturals Happy Traveler, and generic meclizine brands were dominating paid and organic placements. NausX had no strategy to differentiate or defend.
