The situation
A national garage door manufacturer had been working with a large agency for several years. On the surface, things appeared to be running — monthly reports were being sent and campaigns were active.
But when a new marketing manager stepped into the role, the cracks became obvious.
There was no conversion tracking. Google Analytics had never been properly configured. The account was still running on Universal Analytics — over a year after it had been sunsetted by Google. The agency's reporting only showed clicks and impressions, with no visibility into what was actually generating leads.
When we were brought in, there was no account access, no historical conversion data, and no way to benchmark what had come before. We were starting from zero.
What we did
Built a brand new Google Ads account — clean structure, no inherited mess
Set up proper conversion tracking — phone calls, form submissions, mapped to real leads
Configured Google Analytics (GA4) — giving the client full visibility for the first time
Wrote new ad copy targeting high-intent search terms across every product category
Launched with Search campaigns first — built a data foundation before expanding
Scaled into Performance Max once we had enough conversion data to feed the algorithm
Expanded into YouTube and Demand Gen to capture awareness-stage audiences
Supported a full website rebuild — improving landing page experience and conversion rates
The results
Within the first months, the account was generating measurable leads for the first time in the client's digital advertising history. Cost per lead dropped from $18.63 in month one to $7.80 at its best, with a sustained average well under $12. Lead volume grew by over 70% as the account matured and expanded into new campaign types.
The client now has full transparency across every campaign, every dollar, and every lead.
Before vs after
“Crombie Collective took over our digital advertising after years with a larger agency. The difference was immediate — for the first time, we had full visibility into our campaigns and could see exactly what was driving leads. The results have been excellent, and Allie’s hands-on approach means nothing gets missed.”
