Brand Overview
Lang Water transforms tap water into high-quality mineralized water and natural, low-calorie drinks. Their innovative solution removes the need for single-use bottles or heavy transportation of beverages. In November, Lang Water set a goal to grow its sales while reducing ad inefficiencies.
Challenge
Lang Water entered August 2024 with ad campaigns that were missing the mark. Despite an ambitious ad spend of €1,543.61, sales trailed at €1,306.20, resulting in a staggering ACOS of 118.18%. The brand struggled with high costs, low visibility, and underperforming keywords, which hampered its ability to stand out in a competitive category.
Approach
To turn things around, we focused on improving targeting and refining their ad campaigns:
Conducted detailed research to find relevant, high-converting keywords.
Stopped spending on keywords that weren’t driving results.
Increased bids on terms with strong potential to bring in sales.
Created ads highlighting Lang Water’s benefits, such as eco-friendliness and premium quality.
Ran frequent checks on campaign performance and adjusted strategies based on what was working.
