The starting point

Good work that stayed invisible on Google.

Smart Solar Services installs solar panels in and around Cologne. Customers were happy, but the Google profile showed almost none of it: 15 reviews, 4.7 stars, and the latest entries were months old. Anyone comparing solar companies saw competitors with far more reviews first.

The problem was never the quality of the work. Happy customers simply rarely leave a review on their own. You have to ask them nicely, at the right moment, and do it every single time.

The system

One automation
that asks at the right moment.

No new tool for the team, no manual follow-up. The system ran entirely in the background.

Job marked completeAs soon as a customer was marked complete and closed out in the system, the automation kicked in. Exactly when satisfaction is at its highest.
Personal email sequenceThe customer received a highly personalized, friendly email asking for a Google review, with a direct link to the review form. Anyone who didn't respond got an equally friendly reminder after a while.
SMS and WhatsApp when it fitWhere it made sense, the request also went out by SMS or WhatsApp. Short, personal, one tap away from a review.
Best practices, Google-compliantEvery customer got the same request, no cherry-picking, no purchased reviews. Exactly the mechanics that reliably deliver results in systems like this.
