Two Changes, One Week — and Most Advertisers Missed Both
The third week of August 2026 delivered something unusual: two consequential, confirmed Google Ads changes landing almost simultaneously. The first took effect on August 17. The second is three weeks away, with automatic enforcement starting September 1. Together, they represent the most meaningful shift to everyday campaign behaviour since Performance Max became mandatory.
If you run Google Search, Shopping, or Performance Max campaigns with target-based bidding — and especially if your campaigns have historically beaten their stated targets — you are already operating in a changed environment. Here is a clear-eyed read of what happened, why it matters, and what to do before September arrives.
Change One: Google Now Enforces the Targets You Set (August 17, 2026)
For years, one of the quiet rewards of good campaign management was watching Smart Bidding outperform its own brief. You set a Target CPA of ₹800, and after a few months the algorithm settled comfortably at ₹420. You kept the target where it was, pocketed the efficiency, and moved on. That dynamic is now over.
Starting August 17, 2026, Google changed how Target CPA and Target ROAS strategies behave on campaigns that carry a "Limited by budget" status. Previously, budget-limited campaigns could overdeliver against their targets — and often did. After the update, those campaigns are steered back toward the exact number in the target field, including when budgets are subsequently increased or adjusted.
Google's own example from its Help Center is blunt: if your campaign's Target CPA is set to ₹1,000 but your recent actual CPA has been ₹500, your campaign will now begin delivering closer to ₹1,000. The algorithm is not broken; it is doing precisely what you told it to do. The problem is that many advertisers set those targets years ago, never updated them, and had been quietly benefiting from Smart Bidding's overperformance without realising the gap existed.
The update applies across Search, Shopping, Performance Max, Demand Gen, and Travel campaigns. App, Video Reach, and Video View campaigns are excluded and will retain their existing behaviour. Importantly, Google has clarified that this is not an auction-mechanics change — the ad auction itself is unaffected. Only the bidding behaviour within budget-constrained campaigns has evolved.
Google did provide a migration path. The Bid Target Adjustment Tool, available since July 6, lets you review each affected campaign's recent actual performance and choose from three options: keep the existing target and accept the drift toward it, lower the target to match what Smart Bidding has actually been delivering, or set a custom target aligned with your current business goals. Accounts that were budget-limited at any point in the last twelve months should have received notification emails in early July.
What This Means for Real Estate Advertisers
Real estate provides one of the most instructive examples of why this update bites harder than it might appear. A residential developer or a brokerage running lead-generation campaigns on Google typically operates with a defined cost-per-lead (CPL) target tied to project economics — say, a target cost per enquiry of ₹1,200 for a mid-segment project. In practice, those campaigns may have been converting at ₹600–₹700 for months, partly because brand search volume is consistent and high-intent, and partly because Smart Bidding had room to find efficiency within a constrained budget.
When the August 17 change lands, that same campaign — if it has been running budget-limited — will begin drifting its actual CPL toward ₹1,200. The volume of leads does not necessarily fall, but the cost per lead rises toward the ceiling rather than sitting comfortably below it. For a developer running multiple project campaigns with a fixed monthly lead-gen budget, that drift can translate to meaningfully fewer leads delivered for the same spend, simply because stale targets were never reviewed.
Brand campaigns are especially vulnerable. High-converting brand terms routinely outperform their stated targets, and that overperformance has often cushioned blended account CPLs. A drop in brand campaign efficiency will flow directly into blended lead cost — and for real estate, where a single conversion (a site visit booking or a home loan enquiry) can have significant downstream value, even a modest CPL drift matters.
The immediate action is a target audit. Pull every campaign that has carried "Limited by budget" status, compare the stated Target CPA or Target ROAS against actual recent performance, and use the Bid Target Adjustment Tool to close the gap. If you want your campaign to continue delivering at its historical performance level, you need to actively lock that in — Google will not do it for you.
Change Two: AI Max Auto-Upgrades Begin September 1
Layered on top of the bidding change is a structural campaign-type transition that has been building since April. Starting September 1, 2026, Google will automatically upgrade Search campaigns using Automatically Created Assets (ACA) or the campaign-level Broad Match setting to AI Max for Search. All eligible upgrades are expected to conclude by the end of September.
This is not a rebrand of Dynamic Search Ads. AI Max is a meaningfully different campaign format that combines search term matching, text customisation, and final URL expansion into a single AI-powered layer. When the auto-upgrade fires, affected campaigns will have all applicable AI Max features switched on, with URL controls carried over from existing settings — but with significantly broader AI control over how queries are matched, which landing pages are selected, and how ad copy is assembled.
The Dynamic Search Ads migration, which was originally scheduled for the same September window, has been separately deferred to February 2027 following advertiser feedback. That reprieve does not apply to ACA or campaign-level broad match — those two settings are still auto-upgrading in September as planned. Notification emails confirming the September 1 date went to affected accounts on August 5.
Google's internal data positions AI Max as delivering an average of 7% more conversions or conversion value at a similar CPA or ROAS versus using search term matching alone. Independent results in the market have been more varied, and some advertiser testing has shown ROAS pressure during the transition period. The practical advice from most practitioners is consistent: set a strong performance baseline before the migration, and plan to monitor closely for the first four to six weeks after the upgrade takes effect.
Why Both Changes Demand Attention at the Same Time
Individually, each change is manageable. Together, they create compounding risk for accounts that go into September unreviewed. Consider the scenario: a real estate developer's Search campaigns are running budget-limited with a stale Target CPA, have ACA enabled for asset generation, and are on campaign-level broad match. On August 17, the bidding behaviour shifted. On September 1, the campaign structure changes too. If neither was reviewed before the deadlines, the account enters September with two simultaneous disruptions that are difficult to disentangle in performance data.
The good news is that the audit to address both changes overlaps considerably. Reviewing your campaign's budget status, target accuracy, and asset automation settings in a single pass covers the ground you need before September arrives. The questions to answer are straightforward:
- Which of my campaigns have been "Limited by budget" at any point in the past twelve months?
- For each of those campaigns, what is the gap between the stated Target CPA or Target ROAS and recent actual performance?
- Do any of those campaigns also use Automatically Created Assets or a campaign-level Broad Match setting?
- Have I verified that conversion tracking is accurate and complete before the AI Max transition fires?
That last point matters more than it might appear. AI Max optimises against the conversion signals it can see. If your tracking is broken, shallow, or misattributing leads — a common situation in real estate accounts where WhatsApp enquiries and phone calls often go untracked — the AI Max system will optimise toward whatever it can measure, which may not align with what actually drives project revenue.
The Broader Context: Google Is Closing the Gaps Advertisers Exploited
It is worth stepping back to name what is actually happening here. Google is systematically reducing the distance between the targets advertisers set and the outcomes the platform delivers. The August 17 change enforces stated targets more strictly. The AI Max migration shifts creative and landing page control further toward the algorithm. Both moves reduce the unofficial "free efficiency" that experienced campaign managers had learned to extract from legacy campaign setups.
This is not necessarily bad for advertisers — more predictable bidding behaviour is genuinely useful when scaling campaigns, and AI Max's broader intent-matching can surface demand that keyword lists miss. But it does require that the targets, conversion data, and campaign structures feeding the algorithm be accurate and current. Outdated targets, poor tracking, and unreviewed legacy settings carry more cost in an AI-enforced environment than they did when campaigns had more room to find their own equilibrium.
For marketers running paid media across real estate — or across any sector where lead quality and cost per acquisition are closely managed — the discipline required is the same: treat your Google Ads account as a living document, not a set-and-monitor system. The algorithm has become more responsive and more literal at the same time.
What to Do This Week
With August 17 already behind us and September 1 approaching fast, the priority list is short and concrete:
- Run a budget-limitation audit across all active Search, Shopping, PMax, and Demand Gen campaigns. Identify every campaign whose Target CPA or Target ROAS is materially higher than recent actual performance.
- Use the Bid Target Adjustment Tool to lower targets to reflect what Smart Bidding has actually been delivering — or set a deliberate target based on your current business economics.
- Inventory your ACA and broad match campaigns that will be auto-upgraded to AI Max. Decide whether to migrate on your own terms now, or accept the automatic migration in September with settings carried over.
- Audit conversion tracking completeness before the AI Max transition. If phone calls, WhatsApp leads, or form fills are not being captured accurately, fix that first — the AI system will only be as good as the signals it receives.
- Set a performance baseline now using the last 30–60 days of data, so you have a clean reference point for evaluating post-September performance.
Both changes reward preparation and penalise inaction. The advertisers who review their accounts now will have a clear read on September performance; those who don't will be diagnosing mixed signals across two simultaneous disruptions.
If your Google Ads account spans multiple campaigns, markets, or project phases — as is typical for real estate developers or multi-sector businesses running parallel campaigns — having a structured review process in place is especially important. The Transformics paid media team works with clients across real estate, BFSI, and e-commerce to run exactly this kind of proactive account audit ahead of platform changes. The window before September 1 is still open, but it is closing quickly.
