Previous agency claimed 866 conversions. We found 43 were real. Then we rebuilt it.
Gen Z Trade Group is an electrical trade business. Their previous agency claimed 866 conversions in a quarter. We audited three months of that spend.
Gen Z Trade Group: the previous agency claimed 866 conversions, we found 43.
Of the 866, 823 were soft profile taps rather than enquiries. Our audit found 43 were real, carrying eight dollars of attributed value across the audited period. Over the same window cost per click had climbed 2.5x, and the account was over-built, with thousands of keywords competing against each other.
The rebuild started with measurement. GA4, Tag Manager and Search Console were installed properly, along with Attributable, our server-side attribution engine, provided free as the foundation. No new media spend went out until tracking was live and verified.
Google Ads was then rebuilt campaign by campaign, with the strongest segment split into its own campaign instead of being left inside the account average.
The programme now runs month to month on a fixed monthly cap covering Google Ads and SEO, with Meta retargeting included. A substantial dormant contact database was identified for reactivation.
The engagement.
