AI Overviews hit 14% of shopping queries, ChatGPT ads scale up, and scroll animations go native.

No algorithm fireworks this week — but the ground kept shifting anyway. Between 16 and 22 March, new data showed Google's AI Overviews muscling into shopping queries at 5.6x their November rate, CNBC reported ChatGPT's ad pilot creeping toward real scale, Mozilla handed users an off-switch for AI features, and the CSS that used to require a JavaScript library became a browser default. Add a WordPress security release and a beta milestone for 7.0, and it was a week that quietly redrew where buying decisions happen online. Here's what mattered — and what each item means if your website is supposed to move revenue.

1. AI Overviews now appear on 14% of shopping queries

What happened

On 18 March, Search Engine Land covered a Visibility Labs analysis with a striking number: Google's AI Overviews now show on 14% of shopping queries — up 5.6x from just 2.1% in November 2025. For two years, conventional wisdom held that Google would keep AI answers away from commercial searches because that's where ad revenue lives. That firewall is visibly coming down.

Why this is the week's biggest story

• Shopping queries are money queries. Informational AI Overviews cost you blog traffic. Shopping AI Overviews sit between a buyer and your product page — a fundamentally different threat, and opportunity.
• The growth curve is the point. 2.1% to 14% in roughly four months. If the trajectory holds even loosely, AI-composed answers on commercial searches stop being an edge case this year.
• Eligibility is structural. What gets pulled into these answers is machine-readable product data: Product schema, specs, availability, pricing, honest review markup. Pages built as pretty pictures with thin markup are invisible to the composition layer.

2. ChatGPT's ad pilot expands — slowly, deliberately

What happened

On 20 March, CNBC reported that OpenAI's ChatGPT ad test — live in the U.S. since early February — had reached roughly 5% of ChatGPT mobile users, up from 1% at the start of the month. Ads appear below responses, clearly labelled "Sponsored", and only for logged-in users on free tiers. Industry insiders told CNBC they're excited but frustrated by the deliberately slow rollout, and there's still no generally available self-serve platform.

What it means for your marketing mix

• A second answer-engine ad market is forming. Google spent this week putting AI answers on shopping queries; OpenAI spent it building the machinery to sell placement next to its own answers. Both roads lead to paying or earning your way into AI responses.
• Organic citation is the free version. Until ad inventory is broadly buyable, the way into ChatGPT answers is being the source it quotes — structured pages, clear claims, real expertise.
• Baseline now. Segment referrals from chatgpt.com, perplexity.ai and gemini.google.com in analytics this week, so when budgets shift you're deciding from your own data, not a vendor's deck.

3. Google housekeeping: AI Mode sports cards, a health feature retired, and quiet Local Pack data

The mid-week search-news cycle, captured in Search Engine Roundtable's 19 March recap, was Google in tidy-up mode:

• AI Mode gained live sports entity cards — real-time scores rendered inside the AI experience. Trivial for most businesses, but another marker that AI Mode is becoming a full interface, not a chatbot bolted onto search.
• "What People Suggest" is gone. The health SERP feature Google announced in March 2025 — surfacing health conversations from online discussions — was officially removed after about a year. A reminder that SERP features are rented visibility: they appear, reshape click behaviour, and vanish on Google's schedule.
• Local Pack call buttons are rarer than you'd think. A study flagged a low rate of call-button appearances in Local Packs. If phone calls drive your leads, don't assume Google is surfacing your number — make it unmissable on your own site, one tap from every page.

4. The browsers moved: Firefox's AI off-switch and CSS scroll animations in stable Chrome

Mozilla gives users granular AI controls

On 17 March, Mozilla detailed what's new in Firefox: AI controls that let users turn generative AI features off, on, or customise them feature by feature, plus a rebuilt settings experience with proper search. The design signal matters more than the feature: a browser vendor is betting that a meaningful slice of users want AI out of their way. Recent Firefox releases also shipped platform niceties developers have wanted for a while — the CloseWatcher interface, the hint value for the popover attribute, and name-only @container queries.

Chrome 146's scroll-triggered animations settle in

Chrome 146, which reached stable on 10 March, spent this week getting into real projects — and its headline feature deserves it: scroll-triggered animations in pure CSS, running on the compositor thread. Play, pause and reset animations from scroll position with no JavaScript scroll listeners, no Intersection Observer polling, no main-thread jank. The reveal-on-scroll effects agencies have rebuilt with JS on every project for a decade are becoming a browser primitive. Chrome 146 also shipped the Sanitizer API for building XSS-resistant apps.

5. WordPress: a security release to apply, and 7.0 marches toward April

• WordPress 6.9.4 shipped on 11 March as a security release. If any site you own is still on 6.9.3 or earlier as you read this, patching it is today's job — security releases are the one update category where "wait and see" is the wrong policy.
• WordPress 7.0 Beta 5 landed on 12 March, keeping the flagship release on track for its planned April window. The headline feature is real-time collaboration — Google-Docs-style multi-user editing in the block editor — alongside continued admin redesign work.
• Plan the 7.0 upgrade properly. A major version with a new collaboration engine is exactly the kind of release to test on staging first: verify your plugin stack, your theme, and your editorial workflow before it touches production.

What this week means for your website strategy

Three threads worth pulling together if you're scoping web design or development work this quarter:

• Commercial search is being rewritten in front of us. AI Overviews on 14% of shopping queries and ads inside ChatGPT are the same story from two directions: the answer layer is where buying decisions start. Sites structured for machines to quote — and designed for humans to convert — win both.
• The platform is absorbing your JavaScript budget. Scroll animations, popover behaviour, container queries — features that used to justify heavy libraries are now CSS. A leaner build is faster, and faster pages convert and rank better. When you evaluate a website development company, ask how much of their motion and layout work ships as native CSS versus script.
• Own your conversion surface. A retired SERP feature and missing Local Pack call buttons made the same point this week: visibility you rent from Google can vanish without notice. Your own site — its speed, proof, and calls to action — is the only surface you control.

Frequently asked questions

How big a deal is AI Overviews appearing on 14% of shopping queries?

Very. It's a 5.6x jump from 2.1% in November 2025, and shopping queries are where purchase decisions happen. Product and category pages now need machine-readable structure — Product schema, clear specs, visible pricing and honest review data — to be eligible for AI-composed shopping answers, not just classic blue links.

Should my business care about ads in ChatGPT yet?

Watch, don't spend — yet. As of mid-March 2026 the pilot reaches only about 5% of ChatGPT mobile users, with no self-serve platform generally available. The practical move now is organic: make your site quotable and structured so assistants cite you for free, and baseline your AI referral traffic in analytics before the channel matures.

Do Firefox's new AI controls affect how I should build my website?

Indirectly. Mozilla shipping per-feature toggles to turn generative AI off is a signal that a meaningful slice of users will opt out of AI layers entirely. Your site can't assume an AI intermediary — core content, navigation and conversion paths must work as plain, fast HTML for humans reading it directly.

Are CSS scroll-triggered animations from Chrome 146 safe to use in production?

Use them as progressive enhancement. Chrome 146 runs scroll-driven animation on the compositor thread, so it's smoother and cheaper than JavaScript scroll listeners — but cross-browser support isn't universal yet. Ship the static layout as the baseline, layer the animation on top, and always respect prefers-reduced-motion.

Should I update WordPress now or wait for WordPress 7.0?

Update now. WordPress 6.9.4 is a security release — apply it immediately rather than waiting for 7.0, which is still in beta with an April target. Major-version upgrades should happen on a staging site after your plugin and theme stack is verified, never as a same-day production update.

The takeaway

The week of 16–22 March had no confirmed algorithm update, and it still moved the goalposts. AI answers reached the queries that make money, a second ad ecosystem took shape inside a chatbot, and the browser quietly absorbed another layer of what agencies used to hand-build. The common demand behind all of it: websites that are structurally clean enough for machines to quote and persuasive enough for humans to buy from. Whether that work comes from a specialised build team, a Shopify developer partner, or a search for "web developers near me" — judge them on exactly that pair of outcomes.
