YouTube Video action campaigns for AutoDoc: +44% conversions, −15% CPA
Commentary byROASArchiveOur analysis, not theirsAutoDoc ran YouTube Video action campaigns, and Google reports 44% more conversions with a 15% lower CPA.
The result is described as a split test.
Both numbers moved in the right direction at once.
- Conversions: up 44%, so the campaigns drove more sales or actions.
- CPA: down 15%, so each conversion also cost less.
- No spend, absolute CPA, markets or test length is shared.
The change
Before
The comparison was TrueView Shopping ads, according to the search snippet of Google's case study. The control is not described in more detail.
After
AutoDoc ran TrueView for Action (later renamed Video action campaigns), the YouTube campaign type built to drive conversions rather than views.
Our reading: why it likely worked
Our interpretation, not the advertiser's claim.
- A campaign type that optimises for conversions puts video in front of people likely to act, not just to watch.
- Auto parts are a need-driven purchase, so a clear call to action on video can turn interest into sales.
Caveats: This is Google reporting on its own campaign type, so it is vendor-reported. It is described as a split test, but spend, conversions and duration are not shared. Google's original page is gone, so the figures here come from entries.json and a search snippet of it.
How to run this in your account
- Hypothesis
- If we add a conversion-focused YouTube Video action campaign, then conversions will rise at a similar or lower CPA because video reaches buyers search alone misses.
- Primary metric
- CPA
- Guardrails
- Total conversions
- ROAS
- View-through vs click conversions
- Who should try it
- Ecommerce brands with solid conversion tracking and video assets. It probably won't pay off on very small budgets or with weak tracking.
