1. Google began auto-migrating Search campaigns to AI Max
What happened: On September 1, 2026, Google began automatically upgrading Search campaigns that use campaign-level broad match or automatically created assets to AI Max for Search, with the migration running through September 30. Dynamic Search Ads were not part of this window.
Key players: Google
Why it matters: Query matching and ad text decisions on existing campaigns now shift toward Google’s automation by default.
Implications:
- Marketers should compare conversion volume and cost per acquisition before and after each campaign’s migration date, since search term matching and, for campaigns using automatically created assets, text customization are now turned on by default.
- Marketers should review search term reports and exclusions on migrated campaigns to confirm traffic still matches intent.
- Startup operators building PPC tools should confirm their API integrations handle migrated campaigns, since Google flagged compatibility changes for developers.
2. Amazon rebuilt its ad platform as Amazon Ads Agent
What happened: On September 29, 2026, at its unBoxed conference, Amazon Ads renamed its unified advertising platform Amazon Ads Agent and added agentic AI tools for media planning, buying, and optimization. The launch includes DVA+, a combined buying solution for display, video, and audio campaigns.
Key players: Amazon Ads
Why it matters: It moves campaign setup toward goal-based automation, which places more media decisions inside Amazon’s systems.
Implications:
- Marketers can now set a goal, creative, and budget and let Amazon’s AI run the rest, so teams should track whether automated campaign types perform differently from manual Sponsored Ads campaigns.
- Agencies should ask what pricing and placement detail is reported, since Amazon did not commit to showing how individual winning prices are determined.
- Investors and policymakers can note the launch comes as Amazon defends an FTC lawsuit, filed August 31, over alleged hidden pricing in its Sponsored Products auctions, which Amazon disputes.
3. Shopify opened checkout to AI agents
What happened: On September 28, 2026, Shopify extended WebMCP support to checkout, letting browser-based AI agents complete purchases on eligible merchant stores with the buyer’s authorization. A week earlier, Shopify’s CEO announced a partnership to enable Shop Pay checkout in Meta’s Muse AI agent.
Key players: Shopify
Why it matters: A purchase can now start and finish inside an AI agent rather than on a merchant’s own site.
Implications:
- Marketers may find that orders completed inside an agent do not appear as site sessions, so traffic, conversion rate, and attribution reports may need a separate view.
- Merchants should check agentic channel settings in Shopify admin, since direct checkout on Meta is reported to be on by default for eligible stores [uncertain].
- Startup operators should note that retailers are split, with Shopify opening checkout to agents while some, including Amazon, block agent purchases.
4. Apple will add a redesigned tracking prompt in the EU
What happened: On September 16, 2026, Apple told developers that iOS 27.2 will add an alternative App Tracking Transparency prompt in the EU, mandatory for apps distributed in Germany, France, Italy, Poland, and Romania. EU users can also be asked again one year after their previous choice.
Key players: Apple
Why it matters: Consent wording and re-ask rules are changing for app tracking in major European markets following competition authority action.
Implications:
- Mobile marketers should segment EU attribution reporting by country, since the new prompt is mandatory in five markets and optional elsewhere in the EU, so opt-in rates and measurement coverage may differ.
- Marketers should treat past opt-in rates as a baseline only, since a prior refusal can now be asked again after one year.
- Policymakers can note the change follows findings by competition authorities in Germany, France, and Italy about how Apple’s tracking rules treat third-party apps.
5. Search Console started reporting image-based searches
What happened: On September 24, 2026, Google added a multimodal filter to Search Console performance reports, covering searches that start with an image through Google Lens, Circle to Search, image uploads, and Chrome’s “Search this image.” Google confirmed this traffic was not counted in earlier totals, and the report shows no query data for it.
Key players: Google
Why it matters: Image-initiated search is now a measurable source of visibility, but without the queries that show intent.
Implications:
- Marketers comparing impressions across periods should annotate September 24, since the report now includes traffic that earlier totals did not.
- SEO teams with image-heavy sites can see which pages appear for camera-based searches, but cannot assess intent without query text.
- Researchers should note Google has not published how much search volume arrives through these entry points.
6. A Lagos court ruled against Meta’s ad profiling consent model
What happened: On September 25, 2026, a Lagos High Court ruled that Meta processed six Nigerian users’ data for behavioral advertising without a lawful basis, rejecting its terms of service as valid consent. The court awarded $100,000 in damages and ordered compliance steps within eight weeks, and Meta filed an appeal on September 30.
Key players: Meta
Why it matters: It is a first-instance ruling, but it tests whether general terms of service can serve as consent for ad profiling in a major African market.
Implications:
- Marketers using behavioral targeting in Nigeria should watch for targeting or reporting changes during the court’s eight-week compliance window, which runs to November 20.
- Marketers should review how consent is collected for audience data, since the court found general terms of service insufficient for profiling.
- Policymakers and researchers should note the court applied the Nigeria Data Protection Act’s lawful basis and cross-border transfer rules to behavioral advertising.
7. A judge declined to break up Google’s ad tech business
What happened: On September 2, 2026, Judge Leonie Brinkema declined to order Google to sell its AdX ad exchange and imposed behavioral remedies instead in the Justice Department’s ad tech case. The full opinion was unsealed on September 16.
Key players: Google
Why it matters: Google keeps its ad tech stack but must change how it works with rival tools, which shapes the terms of open-web ad buying and selling.
Implications:
- Marketers buying open-web display should note the remedies target how Google’s exchange and ad server treat rival tools, including Prebid integrations and equal-terms bids, which bears on auction access and competition.
- Marketers and publishers cannot yet measure effects on pricing or yield, since the final judgment terms were still being drafted in September.
- Investors can note the court rejected all three structural remedies, and Google has said it will appeal the underlying liability ruling.
8. IAB Europe research shows agentic buying expectations ahead of deployment
What happened: On September 24, 2026, research from IAB Europe covering 50 advertising executives across 44 European markets found 58 percent expect agentic ad buying to reach operational use or scale within a year. Among 47 respondents, 36 reported either no agentic system running day to day or one that people still direct.
Key players: IAB Europe
Why it matters: It documents a gap between expected and actual use of AI agents in media buying, with security and privacy as the leading concerns.
Implications:
- Marketers should note agents are mostly used for reporting, analysis, and optimization today, and respondents mainly judge them on efficiency rather than attribution.
- Agency strategists should note readiness differs by size, with 86 percent of companies with 501 or more staff running advanced agent systems against 48 percent of smaller ones.
- Researchers should be cautious generalizing from a 50-respondent sample, which measures expectations rather than performance.
