Big PMAX Updates For Google Ads - August 2026
TL;DR: Google is making Performance Max more automated and stretching what "PMax" even means. Budget-limited campaigns now push much closer to the CPA or ROAS target you actually typed in, and selected Local Services Ads are becoming a specialized PMax campaign type. At the same time, an early channel-prioritization test hints that advertisers may eventually get some say over where PMax spends.
Your Performance Max campaign didn't change this month.
Its CPA might have.
That's the biggest Google Ads story of August 2026. On August 17, Google changed how budget-limited campaigns chase their bid targets. No setting moved. Nothing showed up in most accounts. The bidding just got more literal about a number you typed in months ago and stopped thinking about.
Google also began turning Local Services Ads into Performance Max campaigns, gave its generative video tools permission to invent parts of your footage, and took away another targeting control. Then, quietly, it started testing something that would hand a control back.
The Monthly Highlight
Your PMax target is now a real target
Plenty of budget-limited campaigns have spent years quietly beating their targets.
Say your PMax campaign carries a $100 target CPA and has been delivering conversions at $60. Most advertisers read that $100 as a ceiling: a number that keeps Google honest while the campaign does better than it was asked to.
Starting August 17, Google began optimizing those campaigns more closely toward the target actually entered. If the target says $100, Google now treats $100 as permission to buy conversions at roughly $100.
That can mean more conversions. It can also mean your CPA climbs by more than half while nobody touches the campaign.
The same logic applies to Target ROAS. A budget-limited campaign that has been returning well above its target will drift down toward the number you set.
Google is not changing your target or your budget. It is changing how hard the bidding system tries to hit the target already sitting there, and that distinction is the whole story. A target you set months ago and forgot about because the campaign kept outperforming it is no longer harmless.
This isn't PMax-only. Google says the change applies to budget-limited Target CPA and Target ROAS campaigns across several campaign types, warns that affected campaigns may see temporary traffic and performance swings, and notes that forecasts in tools like Performance Planner may be less accurate through the August 17–31 transition.
So go audit them. Every budget-limited campaign on Target CPA or Target ROAS. For each one, answer a single question: is this target the result the business actually needs, or is it a number that survived because Google kept beating it?
Targets aren't loose suggestions anymore.

The Big Changes
Local Services Ads are becoming Performance Max campaigns
Starting August 1, Google began migrating selected U.S. Local Services Ads advertisers into a Performance Max campaign type with pay-per-lead goals.
This is not standard PMax wearing a new label. These campaigns stay keywordless. Advertisers keep paying for valid leads instead of clicks. Ads stay on Google Search and Maps rather than spreading across the usual PMax inventory.
The first wave covers home and storefront service businesses: HVAC, plumbing, electrical, roofing, pest control, cleaning, lawn care, appliance repair and moving companies.
Campaign management moves into Google Ads, where you handle budgets, leads, service areas and schedules. Core business information keeps coming from your Google Business Profile.
So why call it Performance Max when it doesn't behave like Performance Max?
Because "Performance Max" is turning into the wrapper Google puts around any automated ad product. A campaign can now be PMax while billing per lead, serving only on Search and Maps, and targeting by service instead of keyword. The name is becoming a packaging decision rather than a description of how the campaign works.
One thing to do before your account migrates: historical LSA performance reports do not come with you. Past customer leads transfer. Campaign-level reporting does not. Download whatever history you care about now, because there is no version of this where you get it back later.
Same "Performance Max" name, different campaign underneath
How the migrated Local Services Ads campaign type differs from standard PMax.
Standard Performance Max
- Billing
- Pay per click.
- Inventory
-
Search Maps YouTube Display Discover Gmail
- Inputs
- Asset groups, audience signals and conversion goals supplied by the advertiser.
PMax with pay-per-lead goals
- Billing
- Pay per valid lead.
- Inventory

Search Maps YouTube Display Discover Gmail
- Inputs
- Keywordless service and location targeting, with core details from Google Business Profile.
Google is testing channel prioritization
Google is alpha testing a feature that lets some advertisers raise or lower the priority of individual PMax channels: Search, YouTube, Display, Discover, Gmail and Maps.
Read that again. PMax was sold on the premise that you bring goals, creative and conversion data, and Google decides where the money goes. Channel-level control was the thing PMax specifically did not do.
Directional influence isn't the same as channel budgets. But being able to tell Google that Search matters more than Display, or that a video-heavy campaign should lean harder into YouTube, changes what channel reporting is for. Knowing where PMax spent your money is interesting. Being able to do something about it is useful.
It's an alpha. Don't build a strategy around getting access. It is still the most encouraging PMax development of the month.
PMax moved in two directions this August
More decisions became automated, while one early test points the other way.
Alpha only. Channel prioritization is not generally available and does not promise exact channel-level budget allocation.
Search stops following the PMax language setting
From September 2026, the campaign-level PMax language setting no longer controls ads on the Google Search Network. Search traffic inside PMax follows the automated language-matching behavior now applied to standard Search campaigns. The setting still governs YouTube, Display, Discover and Gmail. Google announced it in August, which is why it lands in this roundup ahead of the rollout.
Why it matters: in multilingual markets this widens which searches and users become eligible, and it adds another case where one PMax setting behaves differently depending on which channel serves the ad. Watch search-term quality and geographic performance after the switch, and stop assuming your selected language acts as a Search restriction.
Video enhancements can generate the parts of the scene you never shot
PMax video enhancements have moved past cropping and reformatting. Google's generative AI can now extend the scene around your existing footage to produce additional aspect ratios, inventing new visual content around the original shot instead of cutting a horizontal video into a vertical frame.
Why it matters: you get placement coverage without shooting a video for every format, and Google gets materially more control over how your creative looks. The opt-out lives in campaign settings under Asset optimization → Video. If your account received a September 4 opt-out notice, decide before that date. Brands with strict visual, legal or product-accuracy requirements should inspect the generated assets rather than assume every extended scene is acceptable.
Local customer optimization for store goals
A new Local customer optimization setting for PMax campaigns with store goals prioritizes people who are near a business location, or interested in one, and look ready to act. Google reads intent across Maps, Waze and local Search formats to find people navigating, planning a trip, or looking for a nearby service.
Why it matters: for businesses where proximity and timing beat awareness, this targets the moment rather than the audience. It is not compatible with online campaign goals or with PMax campaigns using Merchant Center products.
New-customer reporting without new-customer bidding
Google added a "Report on new customers acquired" option that reports new customers and their value without telling Smart Bidding to bid differently for them.
Why it matters: measurement and optimization are separate decisions, and PMax used to make you couple them. Now you can find out how many new customers a campaign produces without assigning them extra value or changing how the campaign buys.
Other Changes Worth Knowing
- Book buttons reached Search and PMax — Reserve with Google booking moved onto paid surfaces. If you have published an appointment action link, it can now power a Book button on your Search and PMax ads, and Google tracks the booking without extra tagging.
- The booking opt-out is an advertiser decision — the "Appointments booked" goal reaches eligible accounts with no opt-in, and the opt-out sits in Google Ads rather than Google Business Profile. Healthcare campaigns are excluded. Audit the action link for every location you manage: a stale link pointing at a generic homepage used to cost you organic clicks, and now sits behind a paid button PMax can push budget toward.
- LSA settings stay editable after migration — service areas, schedules and business categories remain editable inside Google Ads. Business name and physical address stay tied to Google Business Profile.
- Lead workflows for pay-per-lead PMax — campaigns with pay-per-lead goals get dedicated lead-management and reporting workflows in Google Ads.
- Documentation for pay-per-lead PMax — Google published Help Center pages covering campaign settings, targeting options and best practices, the clearest look yet at the campaign type ahead of the wider rollout.
- More asset automation across the board — Google keeps expanding automatic creation and adaptation of campaign assets. Review asset-optimization settings as carefully as you review bidding and targeting.
What to do this week
- Audit every budget-limited Target CPA and Target ROAS campaign, and reset each target to the number the business actually needs.
- If you run Local Services Ads, export your historical performance reports before your account migrates.
- Review video enhancement settings and look at the generated assets, before September 4 if you received the notice.
- Audit the appointment action link for every location you or your clients operate.
- Watch search terms and geographic performance after the September language change.
- Treat channel prioritization as an encouraging experiment, not a feature you can plan around.
August pulled in two directions. Google automated more of PMax, expanded what counts as PMax, and removed another targeting control. Then it started testing the first real channel-level control PMax has ever had.
Only one of those is available to you today, and it's the automation. The most expensive mistake right now is leaving an old bid target in place because Google used to beat it. Google has told you exactly what it plans to do: move your performance toward the number you entered.
Make sure that number is one you would actually sign off on. And if a bidding change moves your CPA by half overnight, you want to hear about it that day rather than at the end of the month, which is what anomaly detection is for.
