Google is once again tweaking the levers advertisers use to control performance and this time, the focus is squarely on helping businesses capture more demand without losing predictability. In a new announcement on its “Accelerate with Google” hub, Google outlined three updates to Google Ads bidding and budgeting: an expansion of Smart Bidding Exploration, a new “promotion mode” for peak periods, and a change to how bidding targets get optimized for budget-constrained campaigns.

Google’s positioning behind this update is particularly noteworthy. As search behavior evolves with the rise of AI, users are submitting longer, more conversational, and highly specific queries than ever before. These intent-rich, long-tail searches often reveal valuable conversion opportunities that traditional bidding strategies can miss. To address this shift, Google is enhancing its bidding capabilities so advertisers can automatically capture emerging demand while continuing to meet their target Return on Ad Spend (ROAS) or Cost per Acquisition (CPA). The goal is to help campaigns scale intelligently without sacrificing efficiency or requiring constant manual optimization.

Here’s what’s actually changing.

1. Smart Bidding Exploration expands to more campaign types

Smart Bidding Exploration lets advertisers set a ROAS tolerance so campaigns can bid on new, previously unknown search queries that are likely to convert without changing core targeting. Google says campaigns already using it see meaningful gains: an 18% increase in unique converting search query categories and a 19% increase in conversions, based on internal data from a one-month test window.

That feature is now expanding to all Performance Max campaigns that don’t use a product feed, opening the door for more advertisers to tap into unfamiliar-but-valuable traffic. Google is also opening a beta for Shopping ads, covering both Performance Max campaigns with a product feed and standalone Shopping campaigns.

Why it matters: This is Google nudging more of the ad ecosystem toward “trust the algorithm, within limits” bidding giving Smart Bidding more room to explore, but with a guardrail (the ROAS tolerance) so performance doesn’t drift too far from target.

2. A new “Promotion mode” for seasonal spikes

Finding new demand is one thing; capitalizing on it during a flash sale, product launch, or seasonal spike is another. Google’s answer is promotion mode, now in beta for Search and Performance Max campaigns.

It lets advertisers schedule temporary increases to their ROAS tolerance and add extra daily budget during a defined peak window. It’s also compatible with campaign total budgets, meaning advertisers can pair the loosened ROAS tolerance with tighter overall budget controls during high-stakes periods.

Why it matters: This essentially formalizes what a lot of advertisers already do manually cranking up budgets and loosening targets around Black Friday or a big launch into a built-in, schedulable feature.

3. Bidding target optimization updates, rolling out August 17

The third change is less flashy but potentially more consequential for day-to-day account management. Starting August 17 (rolling out over several weeks), Google is updating how bidding targets are optimized for campaigns that are limited by budget. The stated goal is more predictable performance that stays closer to advertisers’ actual CPA or ROAS targets as campaigns scale.

Because this could shift performance for budget-constrained campaigns, Google is recommending advertisers review and potentially adjust their CPA/ROAS targets. To help with that, starting July 6, in-account notifications will start surfacing historical performance data and suggested target adjustments.

Why it matters: Budget-limited campaigns have historically been a pain point for predictability. If this update works as described, it should reduce the guesswork of “why did performance suddenly swing” for advertisers whose budgets are the binding constraint.

What advertisers should do now

• Check Performance Max campaigns without a feed Smart Bidding Exploration is now available there automatically.
• Consider requesting beta access to promotion mode or Shopping/PMax Smart Bidding Exploration by reaching out to a Google account team.
• Watch for notifications starting July 6 flagging recommended CPA/ROAS target adjustments ahead of the August 17 rollout.
• Revisit budget-constrained campaigns before the update lands, since those are most likely to see performance shifts.

The bigger picture

Google frames all three updates as part of a broader shift: search behavior is moving from short keywords to complex, specific queries accelerated by AI and advertisers who want to capture that demand need bidding systems flexible enough to chase it. The tradeoff, as always, is control. Features like Smart Bidding Exploration and promotion mode hand more decision-making to Google’s algorithms, with tolerance settings as the main guardrail advertisers retain.

For marketers, the practical takeaway is straightforward: more automation is coming whether or not you opt in, so it’s worth understanding the tolerance and budget controls now rather than reacting after the August rollout.
