Feedback from Teufel

“While using Adspert, we also carried out A/B tests with other vendors, yet Adspert consistently came out on top. Since all of our marketing is handled in-house, it was very important to us to find a solution that looked after and served us directly.

Adspert has definitely bought us a tremendous amount of time throughout our daily work. Additionally, we were able to better manage the budget allocation through the introduction of performance groups. This gave us the opportunity to better serve smaller accounts in particular and monitor the cost-benefit ratio. The optimization of our shopping campaigns via Adspert also works very well and gives us additional capacities in the team.

On a satisfaction scale of 1 to 10, we rank Adspert as an 8. We are very satisfied with the campaign performance and were able to test many different models, thanks to the great selection of modules. Furthermore, the self-service system is easy to use and offers plenty of opportunities. We are already looking forward to the further expansion of Adspert’s functions.

Adspert for us in 3 short words: Performance, Time Saving, Algorithm.”

Due to the company’s expansion in recent years, the number of Google Ads Accounts the company manages has also increased. 

The same applied to existing keyword sets, a larger product portfolio, and new technical features. This made timely, manual bid management an almost-impossible task, not to mention the constantly increasing number of bid adjustments required.

In light of these challenges, the company decided to seek external support to address the following issues:

  • Management of a growing number of accounts and keyword sets
  • An automated, in-house solution to handle such challenges.
