Google's Smart Bidding Exploration feature is now in open beta for Shopping campaigns and Performance Max campaigns with product feeds. Previously, it was only available for PMax campaigns without product feeds. For e-commerce brands running standard Shopping campaigns — which is most of them — this is the first time the feature is available to them.
Smart Bidding Exploration lets Google's AI bid on search queries your campaign wouldn't normally target, within a ROAS tolerance band you define. It's opt-in. But with August 17's broader bidding enforcement arriving in five days, you need to understand how this changes your options before that deadline hits.
What Standard Smart Bidding Gets Wrong
Every Smart Bidding campaign operates on historical conversion signal. Google bids aggressively on queries that have converted before, and avoids or underbids on queries it doesn't have confidence in. Over time, this creates a narrowing effect — campaigns get efficient but also get conservative, sticking to proven territory and skipping anything unfamiliar.
That's fine when your market is stable. It's a problem when you're trying to scale, when competitors are pushing into new search territory, or when there are converting queries your account simply hasn't accumulated signal for yet.
Smart Bidding Exploration is designed to break that narrowing. You give Google a ROAS tolerance band, and it uses that buffer to bid on queries outside your proven set.
How the ROAS Tolerance Works
The tolerance band runs from 5% to 30%. If your Target ROAS is 200% and you set a 10% tolerance, Google will bid on queries where it expects at least 180% ROAS. You're not lowering your target — you're telling the system how much flex it has to explore.
Google reports that campaigns using Smart Bidding Exploration see 18% more unique converting search query categories and 19% more conversions on average. Those are Google's numbers from Google's testing. Take them as directional, not gospel. What the data does establish: you trade some efficiency ceiling for more conversion volume and wider reach.
The feature won't work if you have manual CPC caps or a budget that regularly hits its daily limit. Both constrain the signals the system needs. If you want to test it, remove CPC caps first and make sure the campaign has room to spend.
Why the Shopping Beta Is Worth Paying Attention To
Performance Max with product feeds already carries a lot of Google Shopping traffic. But many accounts still run standard Shopping campaigns — for tighter control over bidding, product prioritization, or query segmentation.
Until now, Smart Bidding Exploration wasn't an option for those campaigns at all. This beta opens it up. If you've kept your Shopping campaigns separate from PMax deliberately, you now have access to the same exploration mechanism without switching campaign types.
The question is whether exploration is right for your account right now. If you're hitting ROAS targets consistently and have budget headroom, this is a low-risk test. If your campaigns are budget-stressed or barely hitting targets, don't run an exploration experiment with money you can't afford to experiment with.
Urgency Badges Are Rolling Out Automatically
Separately, Google has been rolling out "Deal Ends" annotations on Shopping ads — countdown labels like "3 days left" or "5 hours left" that appear beneath product prices when you have a sale running in Merchant Center.
No opt-in required. If your Merchant Center account has a promotion with a valid expiration date, Google may start displaying the badge on your Shopping listings automatically. No new feed attributes, no code changes needed.
The catch: it only works if your promotion data is accurate. If your sale runs through August 20 but the Merchant Center promotion expires August 15, the badge drops off five days early — while you're still running the sale and paying for clicks that see no urgency signal. Open Merchant Center, go to Promotions, and verify every active entry has the correct end date. This takes twenty minutes and it's the kind of thing that quietly costs you clicks during your best sale days.
How to Prioritize the Next Five Days
August 17 is the more pressing deadline. The bidding target enforcement change — where campaigns consistently beating their targets get pulled back toward what you actually set — applies automatically across Search, Shopping, Performance Max, Demand Gen, and Travel. If you haven't audited your bid targets against actual campaign performance, do that today, not Thursday.
For Smart Bidding Exploration: pick one Shopping campaign with solid conversion history, no CPC caps, and a budget that has room to flex. Set a 10% ROAS tolerance. Let it run for two weeks before drawing conclusions. Don't test it on your highest-revenue campaign — use something mid-tier where a rough two weeks doesn't wreck your month.
For the urgency badges: audit Merchant Center. That's it.
Three things, in order: check bid targets before the 17th, fix your Merchant Center promotion end dates, then test Smart Bidding Exploration in one campaign if your account can absorb it.
