What this business does: a used vehicle parts and car breaker company — customers pull their own parts from end-of-life vehicles at member pricing, or buy a whole car to drive away — with paid membership unlocking a discount on everything in the yard.
I built this Membership campaign myself. Before it could work properly, I had to find and fix a tracking problem sitting underneath it.
Membership purchases jumped from 5 in May to 26 in July — a 5.2x uplift — almost entirely attributable to fixing the Purchase event so Meta could finally optimise toward real buyers instead of guessing.
Against £972 in spend, £31,340 in parts and membership revenue puts the Membership Ad at a 32.25x return — a credible number specifically because it's now measuring real purchases.
Targeting men 22–65+ near the two yard locations, filtered to mechanics, repair shops, and active parts-search intent, kept cost-per-purchase efficient on a modest £20/day budget.
£37 → £128 → £24 across the first three months is normal while Meta's delivery is still learning post-fix. The number that matters most right now is purchase volume climbing, not the noisy weekly cost.
Average combined spend per customer sits at £984.65 across parts and drive-away purchases over six months — comfortably ahead of the £32 it costs to acquire a member.
With Pixel tracking now trustworthy, layering in server-side Conversions API is the planned next step to recover signal lost to browser tracking restrictions and further lower cost-per-result.
Figures are rounded from monthly ad-account reporting, May – Aug 2026. Presented for portfolio purposes as part of my role managing paid social for this business.
