Google Ads is testing Video Reach Campaigns automated bidding for eligible accounts. The limited beta lets advertisers launch YouTube reach campaigns without entering a Target CPM (cost per thousand impressions). Instead, Google adjusts auction bids to help use the available budget. The option and its account-level restrictions are explained in Google Ads Help.
The change, reported on October 10, 2026, removes some bid-setting guesswork. It does not guarantee cheaper impressions or stronger brand impact. For advertisers, the real question is whether automated delivery reaches more of the right people at a sensible cost.
What changes with Video Reach Campaigns automated bidding?
Previously, advertisers typically entered a Target CPM when setting up eligible Video Reach Campaigns. A restrictive target could limit delivery and leave some budget unspent. In the beta, the default automated option does not require a bid amount, although advertisers can still choose a Target CPM for greater cost control.
| Decision | Automated bidding | Target CPM bidding |
|---|---|---|
| What you enter | Budget, dates, targeting and creative, with no bid target | The same inputs plus a Target CPM |
| What Google manages | Auction bids intended to deliver the budget efficiently | Auction bids intended to maximize impressions or views while keeping average CPM at or below the target |
| Main advantage | Less bid guesswork and fewer delivery constraints | More control over average impression cost |
| Main risk | CPM can rise when the system tries to spend against a narrow audience | A restrictive target can limit reach or leave budget unspent |
| Best starting point | Broad awareness tests without a reliable historical CPM | Campaigns with established cost limits or an agreed media efficiency threshold |
A Target CPM is an average-cost objective, not a hard price ceiling for each auction. Automated bidding aims to deliver the campaign budget, but it is not Target CPA or Target ROAS bidding and should not be presented as conversion optimization. For a broader comparison, see our Google Ads bidding strategies guide.
Which Video Reach Campaigns are eligible?
Google lists three supported Video Reach Campaign subtypes in the beta:
- Efficient reach: focuses on reaching more unique people across eligible formats.
- Non-skippable reach: delivers a message in non-skippable video formats.
- Target frequency: is designed around repeated exposure to an audience.
The feature supports daily or campaign-total budgets and eligible placements across YouTube, Google video partners and Google TV. It is not available for Video View Campaigns. Access is limited to eligible accounts, and Google has not announced a general-availability date. If the automated option does not appear in your account, continue setting a Target CPM.
How to set up automated bidding in Google Ads
The setup is straightforward once your account has beta access:
- Create an eligible video campaign. In Google Ads, select Campaigns, create a new campaign, choose “YouTube reach, view, and engagement” (or proceed without goal guidance), select Video, and choose an eligible Video Reach subtype.
- Leave the bid unset. After entering your budget, dates, targeting and creative, find the Bid section at the ad group level. Keep the default setting without a bid for automation. To retain cost control, select “Set a target tCPM” and enter your preferred amount.
- Adjust after launch if needed. Go to Ad groups, open Edit settings and Bidding, then check or uncheck “Set a target” and save. Google also supports switching directly in the ad group table.
Google recommends allowing the automated system an initial 24-hour ramp-up before making major audience or budget changes. This is practical setup guidance, not a guarantee that performance has stabilized after exactly one day. See Google’s instructions for the full workflow.
When automated bidding helps, and when it can cost more
The strongest use case is an awareness campaign with a defined audience and creative, but limited historical CPM data. Removing a restrictive bid target can help the campaign deliver. The tradeoff is that Google may bid more aggressively to spend a large budget against a small audience.
Consider an illustrative $6,000 video budget. At a $10 average CPM it buys about 600,000 impressions; at $15 CPM, about 400,000 impressions. Neither number tells you how many unique, relevant buyers saw the video, whether frequency was excessive, or whether the message landed. These are examples, not measured outcomes from the beta.
For B2B SaaS, this distinction matters. A broad product launch may benefit from flexible reach buying; a tightly defined account list may need a more conservative CPM and budget. The same principle applies to channel planning in our PPC budget allocation framework.
What B2B advertisers should measure
Before choosing automated bidding over a Target CPM, compare delivery and business relevance instead of simply checking whether the budget was spent:
- Unique reach and frequency: did the campaign reach new people in the intended market, or repeatedly reach the same viewers?
- Average CPM and delivery: did broader delivery justify any increase in impression costs?
- Audience, placement and creative quality: review available reports and exclusions, then test genuinely different messages. Better bids cannot fix unclear creative.
- Supporting demand signals: monitor brand search interest, qualified site visits or suitable brand-lift research, without claiming every later lead was caused by a view.
For audience expansion, our report on Google Lookalike Segments for video brand campaigns covers a related change. But audience signals still need validation against customer fit. For downstream reporting, see how to connect ad spend to pipeline, while recognizing that awareness is harder to attribute than a tracked conversion.
How to test automated bidding against Target CPM
- Set a baseline. Document the existing campaign’s budget, creative, targeting, average CPM, unique reach and frequency. Compare with an equivalent test when practical.
- Keep the comparison fair. Avoid changing the audience, budget and creative at the same time as bidding. Respect Google’s initial 24-hour adjustment recommendation.
- Judge reach quality, not spend alone. Look at performance over a meaningful campaign period. If automation spends more consistently but raises CPM without improving relevant unique reach, keep the Target CPM control.
Frequently asked questions
Is automated bidding available in every Google Ads account?
No. This is a limited beta for eligible Google Ads accounts. If the automated bidding option is not available, continue using a Target CPM for your Video Reach Campaign.
Does automated bidding for Video Reach Campaigns optimize for leads or conversions?
No. This beta automates bids for reach-oriented video delivery. It is not the same as conversion-focused Smart Bidding strategies such as Target CPA or Target ROAS.
Can you switch from automated bidding back to Target CPM?
Yes. Google says you can switch between automated bidding and a Target CPM in ad group settings or directly from the ad group reporting table, subject to account eligibility.
Does automated bidding guarantee a lower CPM?
No. Google aims to use the campaign budget efficiently, not guarantee the lowest CPM. Compare average CPM, unique reach, frequency and audience fit before deciding whether automation performs better than your existing target.
OneMetrik takeaway
Automated bidding is a useful shortcut when the starting CPM is uncertain. But full budget delivery is not the same as efficient advertising. For B2B teams, audience quality, suitable frequency and the role of awareness within the wider media plan still matter most.
Our approach would be to test the beta on one suitable awareness campaign, benchmark it against Target CPM and expand its use only if the cost and quality of reach justify the change. Let Google handle auction bids, not the media strategy.
