When a new website breaks conversion tracking, every conversion looks more expensive.

We managed this Audi dealer’s Google Ads account for two years: July 2020 through June 2022. In the first year conversions held steady at around 200 a quarter. Cost per conversion sat at about €13 to €20 in the first three quarters and rose to around €35 in Q2 2021. After about a year the dealer got a new website, and during that rebuild conversion tracking did not work properly. When the new site launched, we set up tracking again. Only after that did measured conversion volume climb sharply.

The curve says the most. In the first year conversions (red) sit around 200 per quarter. Cost per conversion (yellow) sits between €13 and €20 in the first three quarters and around €35 in Q2 2021. During the website rebuild, tracking did not work properly and cost per conversion rose to almost €90 in Q3 2021. After the new site launched with new tracking, volume jumps to about 1,700 conversions in Q1 2022 and almost 4,000 in Q2 2022. Before and after the rebuild were measured with different tracking, so the two periods are not directly comparable.

Below the chart is the Biggest changes panel. It compares cost for Jul 2020 to Jun 2022 with the two years before, Jul 2018 to Jun 2020. The Audi ad group cost €7,509.94 less than in those two earlier years (−51.7%). The Audi e-tron ad group had no cost in those earlier years and came to €3,207.65 from Jul 2020 to Jun 2022. The panel only shows that difference in cost, not what it delivered.

Fix the tracking first

01 · Diagnosis · the cost-per-conversion spike was a measurement problem

After about a year, the dealer decided to rebuild the website. During that rebuild conversion tracking did not work properly. Fewer conversions were recorded and cost per conversion went up, to almost €90 in Q3 2021. Those numbers said more about the measurement than about the campaigns.

02 · Repair · new tracking when the site launched

When the new site launched, we set up conversion tracking again. We managed the account continuously throughout the period and adjusted based on what the numbers showed.

After the launch, measured conversions rose sharply: about 1,700 in Q1 2022 and almost 4,000 in Q2 2022, at roughly €3 to €6 per conversion. Those numbers come from the new tracking, so we don’t set them against the first year’s cost per conversion as a before-and-after.

A sudden spike in cost per conversion is often a measurement problem first.

Boring, predictable, attributable. That’s what good PPC looks like.
