Rainbow Chalk Case Study: How We Grew a DIY Brand's UK Amazon Revenue 21% in 30 Days

About the brand

Rainbow Chalk is a DIY-driven brand specializing in high-quality liquid chalk markers and home improvement essentials. Their signature markers are designed for both ease-of-use and vibrant performance, trusted by casual hobbyists, families, and creative professionals alike.

With a commitment to quality and practicality over frills, Rainbow Chalk has carved out a strong presence in the U.S. market, becoming a go-to choice for those who want reliable products that deliver both creativity and value.

The Problem

After dominating the U.S. market, Rainbow Chalk expanded to the UK. But despite their product quality and pricing advantage, growth stalled.

• Ads were unprofitable with rising ACOS and poor targeting.
• Organic rankings were weak, limiting visibility in a new market.
• Multiple agencies cycled through, each applying generic strategies that didn't work.

Rainbow Chalk didn't need another agency. They needed a strategy tailored specifically for the UK market, not recycled U.S. tactics.

The Solution

We built a UK-specific growth strategy focused on visibility and profitability:

1. Listing optimization
Their listings looked polished but lacked high-volume UK keywords. We identified missing search terms and integrated them into titles and bullets, building the foundation for long-term organic growth.

2. SEO-PPC alignment
Instead of running ads in isolation, we aligned PPC targeting with listing keywords. We also targeted competitor products with higher prices and fewer reviews, capturing customers looking for better value.

3. Category repositioning
Products were buried in the wrong subcategories. We reclassified them to match top-performing competitors, instantly improving visibility in search filters.

4. Conversion rate optimization
We launched systematic A/B tests on hero images, product titles, and A+ content to continuously improve conversion rates and maximize the impact of increased traffic.

The Results

We increased Rainbow Chalk's UK revenue by 21% in 30 days

• Reduced ACOS by targeting mid and long-tail keywords and competitor products with higher prices and fewer reviews.
• Boosted organic rankings by running ads for keywords used in the listings.
• Lifted conversion rates through A/B testing hero images, product titles, and A+ content.

Where other agencies struggled, we achieved profitable UK growth in one month through targeted keywords, smart categorization, conversion rate optimization, and unified SEO-PPC strategy.
