This fast-growing SEO agency was known for driving real search results, but under the hood, their websites had tracking gaps, poor form reporting, and missing conversion data. That made it harder to prove ROI for their clients. The risk? Losing big retainers due to “performance concerns” that they couldn’t even verify. They needed a clean data set and clear reports to keep clients confident.

The solution

We stepped in to audit and rebuild all GA4, GTM, and form tracking across key client sites. We added uptime monitoring and rolled all this into a single dashboard that they could share with clients. With clearer insights, the team could spot quick wins and fix conversion bottlenecks, without hiring in-house.

Key results & metrics

With clear data, the agency stopped churn dead in its tracks, added valuable upsells like uptime monitoring, and rebuilt client trust. They kept a major retainer on the books and turned the tracking headache into a profit centre, all while staying lean.

Client feedback

“We don’t have in-house developers, and hiring one didn’t make sense for the work we needed. LunarWP gave us the confidence to say ‘yes’ to clients when they ask for reports and insights, and we’ve turned that into real extra revenue. It’s like having an invisible data team without the cost.”

– Holly S, Head of Agency
