Case Study: How We Grew a Hong Kong FMCG E-commerce Brand’s Traffic by 300% with Green SEO

Client Overview

Business Type: E-commerce store specializing in premium bottled teas and healthy beverages
Industry: FMCG (Fast-Moving Consumer Goods) – Food & Beverage
Market: Hong Kong & Macau

 

 

The Challenge

Our client, a well-established Hong Kong beverage brand, faced a significant digital transformation challenge. Despite having strong offline retail distribution across major supermarket chains and convenience stores in Hong Kong and Macau, their online presence was virtually non-existent.

The brand’s e-commerce website suffered from multiple critical issues:

• Poor search visibility:The site ranked poorly for both branded keywords and essential category terms
• Technical performance issues:Slow loading speeds that frustrated potential customers
• High carbon footprint:Heavy media content and inefficient hosting created environmental concerns
• Missed opportunities: Low organic traffic meant they were losing potential sales to competitors

This disconnect between their strong offline presence and weak digital performance was particularly problematic in a post-pandemic market where Hong Kong consumers increasingly turned to online shopping for everyday essentials.

2. Environmental Alignment:Reduce website carbon emissions to support the brand’s sustainability positioning in the competitive FMCG market
