10x monthly sales in five months for a new nail clipper launch

Zetwerk launched an ergonomic nail clipper with a rotating head on Amazon US in early 2025, with almost no sales history. We rewrote the listing, built the advertising from scratch and aimed it at seniors and people with limited grip, growing monthly sales from $490 in March 2025 to $4,945 in August 2025.

The Starting Point

The Challenges Holding the Brand Back

A launch with no traction

The clipper sold $120 in February 2025 and $490 in March 2025, with no sales badge to reassure shoppers.

A listing that did not convert

The original title and bullet points did not explain who the clipper was for or why the rotating head mattered.

Limited stock during the launch

Stock ran low in April 2025, so ads were held at $1 a day to keep gathering data until the next shipment arrived.

What We Built

Rebuilding the Foundation for Scalable Growth

01

Listing rewrite and creative

  • Rewrote the title and bullet points, which tripled the conversion rate (February 2025)
  • Reordered the images, added a 3D model and put the top search terms into the A+ content
  • Redesigned the A+ content and the full image set (July 2025) and added a brand story to the store
02

Advertising built from scratch

  • Sponsored Products, Sponsored Brands and Sponsored Display, with competitor brand terms added as negatives
  • Harvested converting search terms from Auto, Phrase and Broad campaigns into Exact match
  • Video ad campaigns (May 2025) and retargeting of shoppers who viewed the product
  • A keyword analysis showing Phrase match converted better than Broad, used to shift bids (July 2025)
03

Targeting the shoppers who need it

  • Focused spend on senior audiences, which were driving good sales by June 2025
  • Added long-tail terms such as "nail clippers for weak hands" and "arthritis nail clippers"
  • Product targeting on competitor clippers with strong return
