Major Google Ads Update 2026

Google is changing the rules for campaigns that use goal-based bidding strategies (such as Target CPA (tCPA) or Target ROAS (tROAS)) and have a “Limited by budget” status.

Starting August 17, 2026, the system will optimize differently to make performance more predictable. Let’s break down exactly what is changing, why your performance might drop if you take no action, and how to prepare using the new tool available as of July 6, 2026.

What’s Changing: Goodbye to “Accidental” Outperformance

How it works now:

If your campaign is limited by budget, it can often outperform your set goals (e.g., bringing in conversions significantly cheaper than your target). However, any budget adjustment leads to noticeable performance fluctuations.

What happens after August 17, 2026:

Google is aligning its algorithms. Now, budget-limited campaigns will strictly and steadily adhere to your specified target. On one hand, this ensures stability when budgets change. On the other hand, if your campaign was previously performing better than your target, its metrics may artificially adjust (i.e., decline) to meet your official limit.

A Simple Example:

You set a target CPA of $10, but because the budget was limited, the algorithm managed to find conversions at $5. After August 17, the system will optimize the campaign so that the actual CPA moves closer to your official $10 target. To keep your $5 results, you will need to adjust your settings.

Which Campaigns Will Receive the Update?

The changes do not apply to all ad types. Check your campaigns using the table below:

Getting Updated on August 17	Already Operating Under the New Rules	NOT Supported (Old Behavior Persists)
* Search campaigns * Shopping campaigns * Performance Max * Demand Gen * Travel campaigns	* Display campaigns * Hotel campaigns	* App campaigns * Video reach campaigns * Video view campaigns

The update will be rolled out across all major platforms: Google Ads, Search Ads 360, Display & Video 360, Google Ads Editor, and Google Ads API.

5 Options for Action: How to Protect Your ROI

As of July 6, 2026, a notification with a link to the new Target Bidding Adjustment Tool has appeared in Google Ads accounts. Google will not automatically change your settings, so the choice is yours.

Option 1. Leave Everything As Is

• Who it’s for: Advertisers who are completely satisfied with their current configured targets (even if actual results are currently better).
• What happens: After August 17, campaign performance will adjust to closely match the set target. Results will become more stable, but your cost-per-conversion may rise to your stated limit.

Option 2. Adjust the Target to Match Recent Performance (Recommended!)

• Who it’s for: Advertisers who want to lock in their current great performance (e.g., keep getting conversions at $5 instead of the target $10).
• What to do: Open the target bidding adjustment tool and click “Apply.” The system will automatically update your targets based on your actual recent historical data.

Option 3. Set a Custom Value for Your Target

• Who it’s for: Advertisers looking for a sweet spot between current performance and scaling.
• What to do: Manually enter a new target value in the tool (e.g., $7 instead of $10). After the update, the system will optimize spend toward this new number.

Option 4. Change Your Bidding Strategy

• Who it’s for: Advertisers who simply want to squeeze the maximum volume out of their existing budget without being tied to a specific conversion cost.
• What to do: Switch to “Maximize Conversions” or “Maximize Conversion Value.” Your volume will be maintained, but keep in mind that actual CPA or ROAS will fluctuate when you adjust your budget.

Option 5. Increase Budget and Scale Up

• Who it’s for: Advertisers ready to acquire more customers at their current targets.
• What to do: Raise your daily budget significantly above your average daily spend. Since budget limitations will no longer cause algorithmic turbulence after August 17, you can scale your campaigns predictably without losing stability.

Tip from Google

After increasing your budget, give the system 1–2 conversion cycles to adapt before evaluating final performance.
