What is Google Ads API v24.2 and why is it important for sellers?

Google Ads API v24.2, released June 25, 2026, introduces mandatory AI transparency labeling for synthetic content to comply with the EU AI Act, multi-party approval security, and new Performance Max placement reporting. Sellers must upgrade to this version to maintain API access and avoid compliance issues.

How does the Smart Campaign deprecation in Google Ads API affect me?

Starting August 3, 2026, the Google Ads API will no longer allow creation of new Smart Campaigns. Existing campaigns can still be updated, but you must migrate to Performance Max or other types for new campaigns. Plan your transition now to avoid disruption.

What is TikTok Shop GMV Max and do I have to use it?

GMV Max is TikTok Shop's campaign type that optimizes for gross merchandise value. As of March 2026, it is the only supported type for Sales objectives. All legacy campaign types can no longer be created, edited, or duplicated, so you must migrate your sales campaigns to GMV Max.

How do TikTok's new affiliate policy changes impact my ad campaigns?

TikTok's June 17, 2026 policy enforcement requires stricter landing page URL matching, prohibits advertorial pre-landers, and expands prohibited lead gen categories. You need server-side tracking (CAPI) as pixel tracking becomes unreliable. Review your affiliate funnels immediately to avoid ad delivery issues.

TikTok vs Google Ads 2026: Sellers' Guide to API Shifts & GMV Max

The Google Ads API v24.2 update represents a critical security and compliance overhaul, while TikTok Shop's forced migration to GMV Max redefines social commerce ad strategies for sellers in 2026. As of June 25, 2026, Google released version 24.2 of its Ads API, introducing mandatory AI transparency features for synthetic content labeling, multi-party approval for enhanced security, and new reporting capabilities for Performance Max placements. Concurrently, TikTok Shop's Ad Manager 2.0—effective since March 2026—has made GMV Max the only supported campaign type for Sales objectives, eliminating legacy campaign creation. These parallel shifts require sellers to adapt quickly or risk losing ad delivery and compliance.

What Are the Key Google Ads API v24.2 Updates for Sellers?

The Google Ads API v24.2 rollout on June 25, 2026, is a minor but impactful update. According to the official Google blog, the update includes:

AI transparency: Programmatic labeling of synthetic content to prepare for the EU AI Act, effective August 2026.
Security enhancements: Multi-party approval workflows to prevent unauthorized changes.
New reporting: Placement segmentation for Performance Max campaigns, enabling sellers to see where ads appear across YouTube, Display, Search, and more.
New experiment types: Campaign Mix and Performance Max feature testing for easier A/B testing.

For ecommerce sellers using automated campaigns, the most critical change is the deprecation of Smart Campaign creation via the API, set for August 3, 2026. Search Engine Land reports that while existing Smart Campaigns will continue serving, API users must migrate to Performance Max or other types for new campaigns. This pushes sellers toward Google's AI-driven campaign management, which aligns with TikTok's GMV Max philosophy.

Why Is Google Deprecating Smart Campaigns in the API?

Google is streamlining its automated campaign offerings. Smart Campaigns, launched for small businesses, are being phased out in favor of Performance Max, which leverages AI across all Google properties. The change affects only API-based creation—manual creation via the Google Ads UI may still be available, but API users must update workflows. As noted on Seroundtable, the deprecation has immediate implications for developers and agencies managing multiple accounts programmatically. Sellers relying on Smart Campaigns should audit their current campaigns and plan migration to Performance Max to avoid disruption.

What Is TikTok Shop GMV Max and Why Must Sellers Use It?

TikTok Shop's Ad Manager 2.0, detailed on Zonflip, represents a fundamental shift in TikTok's ad architecture. As of March 2026, GMV Max is the sole campaign type for the Sales objective. Legacy campaign types can no longer be created, edited, or duplicated. GMV Max uses TikTok's algorithm to optimize for gross merchandise value (GMV), automatically placing ads across For You feed, search, and shop tabs. Sellers must transition all sales-focused campaigns to GMV Max, which requires providing TikTok with a product catalog and setting a target return on ad spend (ROAS).

How Does TikTok's Affiliate Policy Overhaul Affect Sellers?

On June 17, 2026, TikTok enforced stricter affiliate policies, as reported by Affiliate Times. Key changes include:

Stricter landing page destination matching: The URL in the ad must exactly match the final URL after redirects.
Flagging of advertorial pre-landers: Pages designed to warm up traffic before the landing page are prohibited.
Expanded prohibited lead generation categories: Certain verticals (e.g., debt relief, payday loans) cannot use lead gen ads.
Server-side tracking (CAPI) recommended: Pixel-only tracking is becoming unreliable due to browser restrictions.

Sellers using TikTok for affiliate marketing must overhaul their tracking and funnel structures. Implementing Conversions API (CAPI) is now essential for stable ad delivery and accurate attribution.

Data-Driven Comparison: TikTok Shop Ads vs Google Ads

Recent data shows TikTok Shop's effectiveness, especially for mid-market DTC brands. According to Online Store News, TikTok Shop achieved 2.1x higher conversion rates than Meta ads for beauty and wellness in Q1 2026. For comparison, Google Shopping Ads typically see conversion rates around 2-3% for ecommerce, while TikTok Shop's conversion rates can exceed 5% when optimized with organic content and intent compression. Below is a comparison table for sellers evaluating both platforms:

Feature	Google Ads (Performance Max)	TikTok Shop (GMV Max)
Campaign Objective	Conversions, ROAS, store visits	GMV (Sales)
Targeting	AI across Search, YouTube, Display, Gmail	AI across For You, Search, Shop tabs
Required Assets	Product feed, images, videos, text	Product catalog, organic content, short videos
Key Metric	ROAS or CPA	GMV or ROAS
Compliance	EU AI Act labeling by Aug 2026	Stricter affiliate and landing page rules
Migration Status	Move from Smart Campaigns to PMax by Aug 2026	Migrate legacy campaigns to GMV Max by Mar 2026

Actionable Checklist for Sellers in 2026

Update Google Ads API: If using API, adopt v24.2 by upgrading client libraries. Test AI transparency labeling for EU compliance.
Migrate Smart Campaigns: Identify all Smart Campaigns created via API. Plan migration to Performance Max before August 3, 2026. Use the v24.2 experiment types to test PMax variations.
Transition TikTok Shop to GMV Max: Ensure all Sales objective campaigns use GMV Max. Provide a complete product catalog with accurate pricing.
Implement Server-Side Tracking on TikTok: Set up TikTok CAPI to replace or supplement pixel tracking. Validate landing page URLs to avoid policy flags.
Test Creative Formats: TikTok's Collage Carousel is outperforming video in some categories, per Zonflip. Experiment with multi-image ads alongside short-form video.
Optimize Google Ads Reporting: Use new placement segmentation in Performance Max reporting to identify high-performing channels and adjust bids.
Monitor Compliance: Both Google and TikTok are ramping up AI transparency and content regulations. Label synthetic content programmatically for Google Ads.

What Is the Future of Ecommerce Ad Platforms?

The convergence is clear: both Google and TikTok are moving toward fully automated, AI-driven campaign management. Google's Performance Max and TikTok's GMV Max share a philosophy of hands-off optimization where the platform controls bidding, placement, and creative assembly. Sellers must relinquish granular control in exchange for algorithmic efficiency. However, these systems require high-quality data feeds and rich creative assets to perform. Sellers who invest in product catalogs, organic content (especially video for TikTok), and robust tracking (CAPI for TikTok, Google's global site tag) will see the best results.

The 2026 shifts—Google's API security and transparency updates, Smart Campaign deprecation, TikTok's GMV Max mandate, and affiliate policy crackdown—demand proactive adaptation. Sellers who update their tools and strategies early will gain a competitive advantage as these platforms refine their AI. The bottom line: embrace automation, but stay compliant and data-rich.
