SEO and AI Industry Update – March 2026

What March’s Changes Mean for Your Visibility

March made one thing clearer: more of the search journey is now happening before the click. Google is expanding AI-led experiences, local discovery is becoming less predictable, and traditional rankings remain volatile. For brands, visibility now depends on more than where a page ranks. The practical challenge is understanding how your business appears across SEO, AI and local discovery.

In Short: What Matters This Month

• AI Overviews are expanding and reducing direct clicks
• Local visibility is becoming more important as AI changes nearby discovery
• Google’s March update continues the volatile SERP landscape
• Commerce and conversion are being pulled closer to the SERP and AI tools, but websites still convert best

For most brands, the takeaway is SEO is still vitally important, but it needs to connect more deliberately with AI visibility and local visibility.

Search Is Moving Closer To The Answer

Business Impact

Brands may lose traffic without fully losing visibility. Buyers are arriving more informed because more of their research is now happening inside Google and AI tools, and we are increasingly seeing that reflected in client conversations as well as rising referral traffic and conversions from LLMs. That means AI visibility is no longer just an emerging topic. It is becoming commercially relevant. Supported by March’s market data, AI Overviews are expanding across sectors and changing how users interact with search before they ever reach a site.

AI Overviews are expanding, and they are changing the click path

What happened

BrightEdge data reported that AI Overviews grew across nine industries, including healthcare, B2B tech, education, insurance, entertainment, travel, ecommerce, finance and restaurants. Search Engine Land also reported data showing organic clicks down 42% in Q4 2025 compared with the pre-AIO baseline. Separately, Chartbeat data showed search referral traffic down 60% for small publishers over two years, compared with a 22% decline for large publishers. 

Why this matters

When Google answers more of the query inside the results page, fewer users need to click through. That shifts value away from rank alone and towards inclusion, citation and how a brand is framed before the visit. It also helps explain why some businesses are finding prospects better informed before the first call or enquiry. In plain terms, visibility now matters both before and after the click.

Google is testing more control over how content is presented

What happened

Google is testing AI-generated headline rewrites in Search after earlier experimentation in Discover. 

Why this matters

Platforms are not just choosing which sources to show. They are increasingly shaping how those sources are presented. Even when your content is selected, you may have less control over the framing a user sees first. For publisher brands this is particularly sensitive, but it is also part of the wider trend towards platform-managed discovery.

What brands should be paying attention to

Look at whether your key pages are built to be understood and cited, not just clicked. Watch for signs that prospects are arriving with more pre-armed questions, stronger comparisons or clearer expectations. And make sure your content is clear enough to survive summarisation without losing the point.

Visibility Is Becoming More Volatile Across Google, AI and Local

Business Impact

Performance may change without a single obvious explanation. Brands that don’t monitor rankings and traffic in a holistic way risk missing what is really happening, especially as AI and local surfaces become more variable. March was a good example of that: many brands saw unstable rankings, even before you factor in wider changes to the SERP experience.

Google’s March updates kept traditional search unstable

What happened

Google launched its March 2026 spam update on 24th of March and said it was completed on the 25th leading to a peak of volatility. Google then began its March 2026 core update on the 27th of March, confirming on the 8th of April that the rollout had completed after 12 days. Independent tracking also showed ranking volatility staying heated through March.

Why this matters

Search performance can still move sharply because of core algorithm and quality-system changes. AI-led change is not replacing SEO volatility. Many brands are now dealing with both at the same time. That aligns with what we saw across client portfolios in March, where rankings fluctuated far more than usual. The practical lesson is simple: strong technical SEO, clear targeting and high-quality content still reduce risk.

Local visibility is becoming part of the wider AI search story

What happened

Search Engine Land’s March local analysis argued that AI is making local discovery less predictable and less repeatable than classic local rankings. Google is also testing AI-generated review replies in Google Business Profile.

Why this matters

A key part of local visibility is consistency of brand information across external sites, including profiles, directories, citations and review platforms. That aligns closely with how AI systems build entity understanding. If your business is described inconsistently across the web, it becomes harder for platforms to trust what you do, where you operate and when you are the right result to surface. That makes local visibility more than a map-pack issue. It becomes part of how search engines and AI systems understand the business itself.

What brands should be paying attention to

Track rankings, local presence and lead quality together rather than in isolation. Review whether your business information is consistent across external platforms. And pay attention to whether profile quality, review handling and local landing-page strength are strong enough to support trust, not just visibility.

Owned Platforms Still Matter, But The Route To Them Is Changing

Business Impact

More discovery and comparison is happening before users reach your website. Even so, websites still matter because conversion remains strongest in owned environments, where brands control messaging, reassurance and UX. At the same time, structured information is becoming more important because platforms increasingly rely on it to assemble answers, recommendations and shopping experiences.

AI commerce is growing, but websites still do the real conversion work

What happened

Google expanded its Universal Commerce Protocol guidance and described it as infrastructure for AI shopping experiences across Google surfaces. OpenAI also shifted its ChatGPT Instant Checkout plan towards connected retailer apps rather than handling everything natively in-chat. Walmart then said checkout through ChatGPT converted three times worse than purchases completed on its own website.

Why this matters

Platforms clearly want to keep more of the discovery and decision stage inside their own environments. But when users are ready to act, the brand’s own site still performs better because it offers more control over trust, UX and conversion flow. That principle extends beyond retail. The same thing applies to quote journeys, booking flows and lead-generation forms.

Structured data and page clarity are becoming more important visibility signals

What happened

Search Engine Land reported that AI Overviews now appear on 14% of shopping queries, up 5.6 times since November. Google also tightened its rules on out-of-stock product pages, requiring clearer alignment between the page experience and Merchant Centre feed status. Search Engine Land published a six-point scorecard for AI-ready product pages. Another study found that 83% of ChatGPT carousel products aligned with Google Shopping results.

Why this matters

AI systems and platform surfaces rely on information that is easy to parse and trust. For ecommerce, that means feeds, product data, imagery and product-page depth. For lead-generation brands, the same principle still applies through services pages, FAQs, trust signals, proof points and structured business information. Clean inputs are becoming part of modern visibility infrastructure.

What brands should be paying attention to

Make sure your website is strong enough to convert the demand created elsewhere. Check whether your most important pages make your offer easy to understand. And treat structured information as a visibility asset, not an admin task.

What to Watch Next

A March study estimated that AI assistants now handle 56% of the search volume of traditional search engines globally, though that figure should be treated as directional rather than definitive. Separately, a Google patent pointed to the possibility of AI-generated personalised pages being shown instead of the original page, though this remains a patent signal rather than a launched feature. Neither is the main March story on its own, but both reinforce the direction of travel: discovery is broadening, and platforms are experimenting with ways to keep users closer to the answer.

What March Tells Us Overall

March did not produce one single turning point. It produced something more useful: clearer evidence that search is becoming more layered. Google is still updating the systems that rank content, but it is also reshaping how content is surfaced, summarised and interacted with. Local visibility is also becoming part of that same picture, especially where external brand consistency helps platforms build confidence in the entity behind the website. That is why visibility now needs a broader view. The opportunity is not to replace SEO, but to connect it more deliberately with AI visibility and local visibility.

Need help?

If you are already investing in SEO or AIO, this is the moment to look wider at how your brand appears across search, AI and local discovery. The question is no longer only where you rank, but how your business is being understood before the click. That is where a more joined-up visibility approach starts to matter.
