Google Ads introduces Promotion Mode and a major bidding update this August

Google Ads, a popular way for businesses to show ads online, is making important changes in August 2026. These updates will help advertisers get better results, especially when demand goes up suddenly, and will make campaign management simpler and more predictable.

1. Smart Bidding Exploration Now Includes More Campaigns

Smart Bidding Exploration is a tool that helps Google decide how much to bid on ads to get the best results. Since 2024, it has been used mainly for Search campaigns. Now, Google is expanding this tool:

• It will be available worldwide for Performance Max campaigns without a product feed.
• A new beta (test version) is launching for Shopping ads, which includes Performance Max with product feeds and traditional Shopping campaigns.

This change means advertisers can explore new ways to reach people and increase conversions across different campaign types.

2. Promotion Mode Helps During Sales and Special Events

Google is also introducing Promotion Mode in beta. This new feature is made for times when demand suddenly spikes, like during sales or new product launches. It allows advertisers to:

• Schedule temporary changes in their ads,
• Increase their daily budgets,
• Adjust their ROAS (Return on Ad Spend) targets for a specific time.

For example, if a store wants to run a special Christmas sale, they can set up Promotion Mode in advance. This makes it easier to handle busy periods without manually changing campaign settings.

3. Changes to How Bidding Targets Are Managed in Budget-Limited Campaigns

Starting August 17, 2026, Google will change how it manages campaigns that are limited by budget but use target-based bid strategies like Target CPA or Target ROAS.

• Previously, these campaigns could over-deliver, meaning they might get more conversions than expected and spend less than the target.
• After August 17, campaigns will more reliably aim for the target, making performance more predictable.

To help with this transition, Google will introduce a new tool called the Bid Target Adjustment Tool on July 6, 2026. Advertisers can use this tool to:

• Review past performance,
• Keep their current targets,
• Adjust targets to better suit their goals,
• Or switch to other bidding strategies.

Why Are These Changes Important?

These updates aim to improve how Google Ads performs:

• Helping advertisers reach new customers by exploring untapped search queries,
• Making campaign management during busy times easier,
• Ensuring more consistent results when scaling campaigns.

When Will These Changes Happen?

• The Bid Target Adjustment Tool will be available on July 6, 2026.
• The new bidding system behavior will start on August 17, 2026.
• The expanded Smart Bidding Exploration and Promotion Mode are already available in beta.

Who Will Be Affected?

All advertisers using Google Ads for Search, Shopping, Performance Max, Display, and other campaigns will see these updates. Google aims to give marketers more control and stability, especially when trying to grow their business or manage seasonal promotions.

In Summary

Google is making big updates to its Ads platform in August 2026:

• Expanding Smart Bidding Exploration to more campaign types,
• Introducing Promotion Mode for peak periods,
• Changing how budget-limited campaigns target performance.

These changes will help marketers achieve better, more predictable results and make campaign management easier during busy times. Marketers should prepare now, especially for the upcoming August 17 change, by reviewing their current campaign targets and adjusting them as needed.
