Through HAGAKURE, A/B testing & Advanced conversion tracking

Welhof is the market leader as a supplier of refurbished/second-hand white goods. Even so, Welhof also competes with players such as Coolblue and Mediamarkt that sell new products.
Second-hand/refurbished products can deliver a big environmental gain. The life cycle of a second-hand/refurbished product extends its lifespan. Good for the environment and your wallet!
Welhof has the ambition to grow revenue through a higher ROAS. Because 90% of revenue comes in via Google Ads, this is an important factor. In 2022, they saw that revenue stayed consistent every month without any growth. The account was, as it were, running on Google's autopilot. Because the budget was already at its maximum, the question was how we could achieve this. Welhof had the ambition of achieving a monthly revenue of €950K (all channels combined). Because this was a big leap, at DGTLbase we saw this as a challenge
Based on in-depth market research
we decided to focus the SEA strategy on three pillars.
CLEAN TRAFFIC / Structure.
Because of the broad approach, the same search terms were also being triggered in different ad groups. This caused confusion in reporting and meant there was no control over the landing page for the keyword in question. The right data is essential for reporting, A/B testing and optimising the campaigns.
A/B Testing TO make optimal use of machine learning.
Through machine learning, Google learns who your potential customers are and targets this group. Once targeted, the ad has to be as attractive as possible to click on. This is where A/B testing comes in. After all, there's no one-size-fits-all.
Advanced conversion tracking
The third aspect to be able to steer better on an automated bidding strategy is using advanced tracking methods. During the analysis, we saw that no use was being made of enhanced conversions, server-side tracking, cookie consent mode, returning vs new customers & POAS tracking.
After implementing advanced conversion tracking, we saw a 20% conversion boost. This lets us feed the algorithm with even more data.
Through a strategic restructuring of the account, a monthly revenue of €950,000+ was reached within 6 months of taking over the account.
We also increased ROAS by 7% while ad spend grew by 32%.
