Google Ads 2026 Updates: AI Labels, Smart Bidding Overhaul & Backlash

The key change in Google Ads this July 2026 is the upcoming overhaul of target-based bid strategies for budget-limited campaigns, set to take effect on August 17, 2026. But that's not the only development. Google also introduced new AI labeling requirements, launched High Engagement ads for App campaigns, expanded Performance Max with a Theme Library, and began turning on Local Inventory Ads by default for Shopping campaigns. Here's a detailed breakdown of each update and what advertisers should do now.

AI Labeling Requirements for Ad Creatives (July 2026)

Starting in July 2026, Google now allows advertisers to label AI-generated or AI-modified image and video ad creatives using either text or visual labels. This change is part of Google's broader effort to comply with emerging AI transparency regulations and to build trust with users. The AI label setting is rolling out gradually across Google Ads and related tools. According to Google's official policy page, advertisers can choose to add labels such as "AI-generated" directly on the creative asset. This is a permissive update: labeling is allowed, not yet mandatory for most ad types, but advertisers should monitor as regulations evolve. The change aligns with similar moves by other platforms and regulators worldwide.

Why it matters: Advertisers using AI tools to generate ad images or videos (e.g., with Google's own AI features or third-party tools) now have a clear path to disclose that fact. This can help avoid potential policy violations and build consumer trust. As AI-generated content becomes more common, transparency will likely become a competitive advantage.

Smart Bidding Overhaul for Budget-Limited Campaigns (August 17, 2026)

On August 17, 2026, Google Ads will change how target-based bid strategies (like Target CPA and Target ROAS) behave when a campaign is "Limited by budget." The official announcement explains that these campaigns will be adjusted to perform more consistently toward their bid targets, even when budgets vary. A new Bid Target Adjustment Tool became available on July 6 to help advertisers review and update their targets before the change takes effect.

The controversy: Many advertisers and industry experts have reacted strongly against this update. Consultant Joey Bidner and others argue that the change could force CPAs to double in some cases, claiming it serves Google's revenue interests more than advertiser performance. A detailed analysis on PPC Land describes the backlash, with practitioners expressing concern that the update effectively raises costs for budget-constrained advertisers while providing little benefit. Google has denied that this is a broader Smart Bidding update, with a liaison clarifying on Search Engine Roundtable that the change only affects budget-limited campaigns using a target, and is not a fundamental shift in the Smart Bidding algorithm. Nevertheless, the debate continues.

High Engagement Ads Setting for App Campaigns

Google Ads is rolling out a new "High engagement ads" setting for App campaigns. When enabled, this feature prioritizes higher-engagement ad formats (such as rewarded ads, playable ads, or interactive video) over standard formats. This gives advertisers more control over the user experience and can potentially improve app install quality and post-install engagement. The setting is available in the campaign settings section.

Performance Max Theme Library

Performance Max campaigns now have a new Theme Library, announced in the same PPC Newsfeed roundup. This tool allows advertisers to create and manage consistent themes across their assets—like colors, fonts, and branding elements—directly within the campaign interface. It simplifies maintaining brand consistency across ad formats and channels without needing external tools. The Theme Library is expected to evolve with more customization options later this year.

Default Local Inventory Ads for Shopping Campaigns

Google Ads will now turn on Local Inventory Ads by default for Shopping campaigns. This change, reported by Search Engine Roundtable, means that retailers who sell both online and in-store will automatically have their local product inventory shown to nearby shoppers. Advertisers can opt out in campaign settings, but the default setting aims to boost foot traffic and omnichannel performance. This is a significant shift for retailers who previously had to manually enable this feature.

What Advertisers Should Do Now

Given these changes, advertisers should take several steps:

1. Review AI labeling — If you use AI-generated image or video assets, consider adding explicit labels to stay ahead of potential enforcement. Check the policy page for specific guidance.

2. Prepare for bidding changes — Use the new Bid Target Adjustment Tool to review your target CPA/ROAS for campaigns that are "Limited by budget." Consider increasing budgets or adjusting targets to mitigate any CPA spikes. Read the official documentation here and the community discussion here.

3. Test High Engagement ads — For App campaigns, enable the new setting and compare performance with standard setups.

4. Explore Performance Max Theme Library — Simplify creative consistency across your campaigns by leveraging the new Theme Library.

5. Check Local Inventory Ads settings — If you're a retailer, verify that Local Inventory Ads are configured as you intend, since they're now defaulted on.

The Bigger Picture: Google's AI and Automation Push

These updates collectively show Google doubling down on automation and AI. From mandatory disclosure of AI-generated content to tweaking bidding algorithms to favor budget-friendly (from Google's perspective) behavior, the platform is clearly moving toward a more AI-driven, less manual future. The backlash against the bidding change underscores a growing tension between advertiser control and Google's machine learning black box. Advertisers who stay informed and adapt quickly will be best positioned to navigate this evolving landscape.
