AI video ads on YouTube: conv. value/cost 1.58, up 0.21
Commentary byROASArchiveOur analysis, not theirs@runtraffic ran AI-made video ads on YouTube for an ecommerce brand and reported a conversion value/cost of 1.58, up 0.21. The post says the account runs at about $20K a day.
There is no control, so the gain can't be tied to the AI creative alone.
- Conversion value/cost: 1.58. This is Google's ROAS-style ratio of reported sales value to spend.
- Change: +0.21 against the previous period in the post's Google Ads screenshot.
- Spend level: about $20K a day, per the post. Total spend for the period is not in our record.
- Not in our record: conversions, CPA, date range or the ads themselves.
The change
Before
Conversion value/cost was 0.21 lower in the previous period, which works out to 1.37 (1.58 − 0.21). What ran then is not shared.
After
YouTube video action campaigns using AI-made video ads, reported at a conversion value/cost of 1.58.
Our reading: why it likely worked
Our interpretation, not the advertiser's claim.
- AI tools make it cheap to produce many video variations, which helps YouTube find versions that convert.
- Holding a ratio near 1.58 at a high daily spend suggests the creative supply kept up with the budget.
- A 0.21 gain is modest, so it could come from seasonality or bidding as much as from the creative.
Caveats: This is a campaign result with no control, from one ecommerce account. Total spend, duration, conversion counts and attribution settings are not in our record, and conversion value/cost is Google's own reported figure.
How to run this in your account
- Hypothesis
- If we add AI-made video ads to our YouTube video action campaigns, then conversion value/cost will rise because we can test more creative variations for the same production cost.
- Primary metric
- ROAS (conversion value/cost)
- Guardrails
- CPA
- View rate or hook retention
- Spend pacing
- Who should try it
- Ecommerce brands already spending steadily on YouTube that are short on fresh video. It probably won't help a brand with no proven offer or no conversion tracking.
Questions
Do AI video ads work on YouTube?
In this one account, @runtraffic reported a conversion value/cost of 1.58, up 0.21. There was no control, so it shows they can work, not that they beat human-made ads.
What is conversion value/cost in Google Ads?
It is the reported sales value divided by ad spend, which is Google's name for ROAS.
A value of 1.58 means 1.58 in reported sales for each 1 spent.
