Google Smart Bidding Exploration Now Covers Shopping Ads

Google Ads now offers Smart Bidding Exploration on Shopping and Performance Max campaigns, according to a Search Engine Land report published October 23.

If you run high-ticket Google Shopping on Target ROAS, you can now tell Google to accept a return 5% to 30% below your target in exchange for bids on searches it has little history on. That is a spend decision, not a free feature, and it lands five weeks before Black Friday. I cover this kind of change for store owners at Ecommerce Paradise because one wrong toggle on a $2,000 product can burn a month of margin.

This post covers the change, the August 17 reset behind it, the break-even math, and a five-step test for the holiday spike. If you are new to the model, start with my guide to what high-ticket dropshipping is first.

Google Adds Smart Bidding Exploration to Shopping and PMax

Search Engine Land’s Anu Adegbola, the site’s Paid Media News Editor, reported on October 23 that Smart Bidding Exploration, previously a Search-only option, now covers three campaign types. Search is unchanged. Performance Max explores additional searches among its existing eligible terms. Shopping explores Search and Shopping traffic when a Merchant Center feed is available, per Search Engine Land.

The mechanics sit in Google’s own help documentation. You pick a Target ROAS tolerance between 5% and 30%, which lowers your effective target so the system can bid harder on queries with plausible but unproven conversion history. Google’s example: a 200% Target ROAS with a 10% tolerance becomes an effective target of 180%, and you can expect to land within about 15% of that effective target over one to two conversion cycles, according to Google’s help page.

Google says the feature changes bidding, not targeting. The same page states that Smart Bidding Exploration “doesn’t expand your broad match keywords or target outer limits.” For a Performance Max campaign with a product feed, one toggle applies exploration to both Search and Shopping traffic. Performance Max without a feed gets Search exploration only.

The eligibility rules matter more than the toggle:

Campaigns must use Target ROAS bidding. The budget should not be the thing limiting the campaign, and Google says exploration may pause when a budget cap is hit. Portfolio bid strategies work only with Search, so moving a Shopping or Performance Max campaign into a portfolio strategy turns exploration off automatically. Search Ads 360 does not support it for Shopping or retail Performance Max campaigns.

One gap: neither Search Engine Land nor Google’s help page says whether the Shopping and feed-based Performance Max versions are generally available or still in beta. Google’s June 15 announcement described Performance Max without a feed as generally available and opened a beta for Performance Max with a feed and standard Shopping, with interested advertisers told to contact their Google account team, per TechWyse. Check your own account before assuming you have the toggle. Shopping exploration also depends on a working Merchant Center feed, so a disapproved or stale feed limits what Google can explore in the first place.

Google’s performance claim is old and comes from Search. Campaigns using the feature saw about 18% more unique search query categories with conversions and about 19% more conversions overall, based on Google internal data from March 11 to April 11, 2025. Google says results vary by advertiser. I could not find published results for Shopping.

From the Aug. 17 Bid Reset to Exploration on Shopping

This did not arrive alone. Ginny Marvin, Google’s Ads Product Liaison, announced the package on June 15: Smart Bidding Exploration for more campaign types, a Promotion Mode beta for temporary budget and tolerance changes, and a bidding target optimization change starting August 17, according to MediaPost’s Laurie Sullivan. Promotion Mode launched in beta for Search and Performance Max, per PPC Land.

The August 17 piece is the one that hurt. Budget-limited campaigns that had been beating their targets were steered back toward the target, which meant entering auctions they had skipped before. In an August 5 Q&A, Marvin said doing nothing “may mean entering different auctions than you previously competed in,” and that in budget-capped campaigns the target becomes the main efficiency control, per PPC Land. I covered Google’s original notice in my July report on the Shopping ROAS reset.

The aftermath is now measured. Agency smec reported that median cost per click for budget-limited Target ROAS campaigns rose 15.8% after August 17, and that impression share lost to budget jumped from about 4% to about 33%. I broke down those numbers and the caveats in my post on the 20% ROAS cushion. smec sells budget and target recommendation software, and it did not disclose its sample size.

There is a counterpoint worth stating plainly. Google’s pitch is that exploration finds converting queries your target was too tight to bid on, and the company’s own figures say it does that on Search. Practitioners Joey Bidner and Julie Friedman Bacchini criticized Google’s rationale and documentation for the August change, according to PPC Land, so trust in Google’s framing is not universal. Nobody has published independent Shopping data on exploration yet, which means both camps are arguing from different evidence.

What a 10% ROAS Tolerance Costs a High-Ticket Store

My read is that this feature is a loan against your margin. You lower the bar, Google spends against the lower bar, and you find out later whether the new queries paid it back. For a low-ticket store with thousands of conversions a month, the system learns fast and the loan is small. High-ticket stores are the opposite: few orders, long consideration, and a lot of dollars riding on each click.

Here is hypothetical math, not reported results. Say a store sells at a $2,000 average order with 25% gross margin after product cost, so $500 gross profit per order. Break-even ROAS is 4.0, or 400%. The campaign runs a 500% Target ROAS.

At a 5% tolerance the effective target is 475%. Google says you land within about 15% of it, so the worst case is roughly 404%. That is still just above break-even: about $495 of ad spend per $2,000 order, leaving around $5 of gross profit. At 10% the effective target is 450%, and the worst case is about 382%. Ad spend per order is about $523, so you lose roughly $23 per order, or about $915 across 40 orders, before overhead. At 20% the effective target is exactly your break-even, and at 30% it sits below it.

The rule I’d use is a threshold, not a ban on the feature: the lowest effective target, minus Google’s 15% wobble, has to stay at or above your break-even ROAS. If you do not know your break-even ROAS to the decimal, you are not ready to pick a tolerance. Tools like Finaloop that tie ad spend to real per-order profit make that number a lookup instead of a guess.

Put that into a decision rule. If the worst case clears break-even at a 10% tolerance, 10% is your ceiling. If it only clears at 5%, run 5%. If it does not clear even at 5%, your target sits too close to break-even for exploration to be safe, and the fix is margin or price, not a bidding setting. A campaign with a 700% target and a 400% break-even has real room to explore. A campaign with a 450% target does not.

The second trap is the budget rule. Google says exploration needs a campaign that is not budget-limited. smec’s data shows impression share lost to budget jumping after August 17, which suggests more campaigns now carry the “Limited by budget” label than before. Turning on exploration in a campaign that is capped does little. Fix the cap first, which usually means either more daily budget or a looser base target, and I would rather raise budget on a proven campaign than lower the target on a shaky one.

Third, high-ticket conversion lag. Google’s one to two conversion cycles can mean several weeks when buyers research a $3,000 outdoor power product or a $2,500 mattress for ten days before they call. Judge the test too early and you will cancel a campaign that was working, or keep one that was bleeding. My guide to turning Google Shopping clicks into sales on high-ticket products covers the on-site side. The click is only the first half of the job, and the complete conversion system post explains the rest.

Timing adds pressure. Deloitte’s holiday work shows shoppers moving into October, per my coverage of that survey. Meta ad prices are also up 23% in the US and Canada before Q4, according to my report on that increase. Google Shopping is where many stores will try to squeeze more volume instead, which makes the temptation to crank the tolerance real.

Exploration also does not fix a margin problem, and it will not rescue a weak product page either. More query categories mean more first-time visitors who do not know your brand, and high-ticket buyers want a phone number, reviews and clear shipping terms before they commit.

If you are fighting on price, the answer is in the offer. I wrote about scaling a high-ticket store without cutting prices. If you would rather hand the store build, feed and launch to a team that does this every day, that is what my turnkey done-for-you service exists for.

Test Smart Bidding Exploration Before Black Friday

Black Friday is November 27, five weeks out. That is enough for one clean test and not enough for three sloppy ones. Run these five steps in order:

Check that the toggle exists. Open one Target ROAS Shopping or Performance Max campaign and look for the Smart Bidding Exploration setting. If it is missing, Google’s June note says the Shopping beta runs through your account team, so email them rather than waiting. Do not rebuild campaigns to get it; moving to a portfolio strategy turns it off.
Write down your break-even ROAS. Take gross margin per order after product cost, shipping and payment fees, then divide 1 by that margin. Pull the true margin from your books using QuickBooks or Finaloop, and add a 10% buffer for returns and chargebacks.
Clear the budget cap. Filter for campaigns marked “Limited by budget” and fix those before testing anything. Use my Black Friday stress-test checklist to decide which campaigns deserve the extra daily budget.
Test one campaign at 5% to 10%. Pick a campaign with steady conversions, set the tolerance so the effective target minus 15% stays above break-even, and freeze other changes for at least two conversion cycles. Log the date. Do not touch assets or targets mid-test, which is also why I would hold off on the Performance Max asset group A/B toggle until the test ends.
Keep the feed honest while it runs. Exploration shifts bids toward queries with thin history, so out-of-stock items and stale prices cost real money. Sync supplier inventory with Stock Sync or Inventory Source, and give a virtual assistant from OnlineJobs.ph the weekly job of reviewing search data and adding negatives.

Frequently Asked Questions

What is Smart Bidding Exploration?
It is a Google Ads option that lowers your effective Target ROAS by a tolerance of 5% to 30% so the system can bid on queries without proven conversion history. Google says it changes bidding, not targeting.

Is it available to every Shopping advertiser right now?
Unclear. Search Engine Land does not say whether it is generally available or in beta, and Google’s June announcement described the Shopping version as a beta handled through account teams. Check your campaign settings first, then ask your Google rep.

What tolerance should a high-ticket store start with?
My opinion: the lowest option that keeps your worst-case ROAS above break-even, which for most stores is the 5% to 10% range. Google’s tolerance runs up to 30%, and that top end is risky on thin high-ticket margins.

Does it work on campaigns that run out of budget?
Not well. Google says the budget should not limit the campaign and exploration may pause when a cap is hit. Fix the cap first, then test.

Could more converting queries mean more chargebacks?
It can change your order mix, so tighten your dispute process before scaling. My chargeback prevention guide for high-ticket stores covers the evidence and policies to have ready.

Does this replace the new-customer value setting Google added recently?
No. They solve different problems: exploration widens which searches you bid on, and new-customer value changes what a first-time buyer is worth to the bidder. I covered the second in my report on the 5x new customer multiplier.

I am not running Shopping yet. Where do I start?
Start with the product, not the bidding. Grab the free high-ticket niches list first. Then work through my 150+ niche breakdown before you spend on ads.
