Google Ads Updates for September 2026: What Changed, and What’s Coming in October

Google doesn’t run on a monthly release schedule — it ships changes almost every day. Here’s what actually mattered from late August through the first part of September 2026, what’s already locked in for October, and what it means if you’re running ads for a local or service-based business.

According to the independent tracker at gadschangehistory.com, Google has logged over 1,000 changes to Ads, Merchant Center and its API since January 2025 — more than one change a day, on average. Most of those are minor. A handful each month genuinely change how you should be running an account. Below are the ones worth your attention, plus what to actually do about them.

What changed in Google Ads this month?

AI is doing more of the account management for you

• AI Dashboards started appearing in advertiser accounts on September 8 — about a month after Google previewed them. Describe the report you want in a text prompt, and Gemini builds the visual dashboard along with a written summary of what moved.
• Automated promotions began rolling out on September 2. Google now scans your landing pages for live offers (“20% off,” “buy one, get one”) and attaches them as promotion assets to eligible Search and Performance Max campaigns on its own. Campaigns already running a manual promotion are skipped, and you can switch it off under Campaigns > Assets > automated assets > Advanced settings.
• AI Mode started serving ads directly. On September 4, Google confirmed a small U.S. test showing standard exact- and phrase-match Search ads inside AI Mode results — inventory that was previously reserved for AI Max and Performance Max. Late August also brought inline Shopping ad carousels to AI Mode responses.

None of this needs setup work on your end, but it does mean more of the decision-making in your account — what shows, what gets promoted, how performance gets explained — is shifting to Google’s AI layer. It’s worth a monthly look at your account to confirm the automation is actually doing what you’d expect.

Local features got noticeably sharper

• Local customer optimization for Performance Max rolled out on August 26. A new toggle prioritizes nearby customers who show immediate intent to visit or contact your business, steering budget toward locally tailored ads across Maps, Waze and Search. It’s built for store-goal campaigns and doesn’t work alongside online sales goals.
• Waze Ads went global on September 4. Performance Max’s Waze inventory, previously limited to the U.S., expanded to roughly 42 countries.
• Store sales measurement is moving into Data Manager. Google announced on September 8 that advertisers will soon connect a CRM or Google Sheet directly to share offline sales data, instead of building a separate upload process — explicitly pitched as holiday-season prep for multi-location and local service businesses.

If your business has a physical address or a defined service area — pest control, HVAC, cleaning, bird control, event services — this is the cluster to watch most closely this quarter. It’s also exactly where good local SEO and paid local targeting need to work together rather than in separate silos.

Bidding and measurement quietly got more forgiving

• Smart Bidding needs less patience now. On August 27, Google shortened its own guidance from “wait 3 cycles or 4 weeks” after a bid strategy or target change, down to just 1–2 conversion cycles.
• Multi-source conversions (a renamed beta, August 25) links your website conversion action to backend data sources through Data Manager, aimed at recovering conversions that ad blockers would otherwise hide.
• A 7-day rule for offline conversions. Google clarified on August 22 that data-driven attribution only models offline conversions uploaded within 7 days of the click. Later uploads still show up in standard reports, but attribution modeling ignores them — which explains a lot of the reporting gaps lead-gen advertisers see when CRM uploads lag.

The broad match → AI Max migration is happening right now

Since August 3, advertisers can no longer turn on campaign-level broad match or legacy automatically-created assets. Google is migrating existing campaigns that used them onto AI Max gradually, through September 30 — you can opt out in campaign settings, or track the change via the campaign’s migration-date fields if you use the API. This is a separate, faster-moving change from the Dynamic Search Ads migration below, and it’s worth checking your own account settings this week if you’ve historically leaned on broad match.

What’s coming to Google Ads in October 2026?

• Local Services Ads will start charging for missed and follow-up calls from October 1. Google will bill for calls missed during business hours when the caller waits more than 20 seconds, plus one follow-up call within 15 days of a valid lead. If your team can’t reliably pick up within 20 seconds, it’s worth fixing your call-answering setup before the 1st.
• Google Tag Manager stops honoring gtag('config') commands from October 2. If your site loads a GTM snippet but still depends on a gtag('config') command to configure Google Ads or GA4 tags, that will stop working. You’ll need the gtag.js snippet, or the newer “gtm init” trigger, to keep a legacy setup running — part of Google’s broader push to make Google tags full GTM containers.
• Campaign-level language targeting is disappearing from Search, rolling out from late September (Google’s own API documentation pins it to September 30). Google will rely on the language of your ads and landing pages, plus its own read of user intent, instead of a campaign-level language setting. If you run multilingual campaigns — common across the UAE and into markets like the UK — keep an eye on search terms and geographic traffic once this lands.
• Google Ads API v22 sunsets on October 7. Mostly a developer-facing note, but relevant if any reporting or bulk-editing tool your team uses talks to the API directly — v23 or later is required, with v25 recommended.

One correction worth knowing: Dynamic Search Ads are not being force-migrated to AI Max this year. Google pushed that automatic migration back from around September 2026 to February 1–28, 2027 — only in-account upgrade prompts start in September. If anyone tells you DSA is being switched off imminently, that’s an outdated timeline.

Which of these actually matter for a small or local business?

If you only track three things this quarter, make it these: the Local Services Ads call-billing change if you run LSAs, the Performance Max local-optimization toggle if you have a physical location or service area, and the broad match → AI Max migration if your Search campaigns lean on broad match keywords. Everything else here is either developer-facing or a smaller interface tweak.

This is also, honestly, the case for not tracking Google Ads changes alone. Our Google Ads management team reviews changes like these against live client accounts every month — including the promotion automation and conversion tracking changes above — so you’re not choosing between running your business and monitoring a platform that changes daily.
