AI Search for Clinics: The May 2026 Update

By Tor Davies

The AI search landscape has shifted materially in the last month, and the bar for clinical content has just been raised significantly. If you run an MSK clinic, the most important development is Perplexity's launch of Premium Health Sources, which effectively creates a two-tier system for health citations. Alongside changes to Google's AI Overviews and the removal of FAQ rich results, the rules for getting your clinic cited have tightened. Here is exactly what has changed and what you need to do about it.

What Is the Perplexity Premium Health Sources Update?

On 5 May 2026, Perplexity integrated BMJ Journals, BMJ Best Practice, and the New England Journal of Medicine directly into its answer engine. This means that for clinical queries, Perplexity now relies on a top tier of peer-reviewed, professionally governed medical literature. As a local clinic, your website cannot compete directly with the BMJ. You are competing on the open-web tier, which means your content must now prove its clinical authority more rigorously than ever to be cited alongside these premium sources.

To compete on the open-web tier, you must stop writing generic "what is physiotherapy" pages and start proving your clinical experience. AI platforms are looking for content that cites primary sources (like NICE guidelines or Cochrane reviews) inline, clear attribution to a specific, credentialled practitioner, and content that answers specific questions directly.

How Have Google AI Overviews Changed?

Google AI Overviews now appear in over 25% of all searches, and for healthcare-related queries, that number exceeds 60% in some categories. The most important structural change is that citations are now embedded inline within the AI response text, adjacent to the relevant sentence, rather than grouped at the bottom. This makes sentence-level extractability the key optimisation target.

Content that contains a clear, self-contained factual statement answering a specific query is far more likely to be cited than content that buries the answer in flowing prose. You need to write content so that every key clinical claim is contained in a single, self-contained sentence that can be extracted and cited inline by AI Overviews.

What Happened to FAQ Rich Results?

Google removed FAQ rich results (the expandable Q&A accordions in search results) for most commercial sites from 7 May 2026, with full removal expected by August 2026. However, the underlying content pattern remains essential for AI extraction. AI systems preferentially extract information from well-structured FAQ content because it provides a clean, self-contained answer to a specific question.

You should continue to write FAQ sections on condition and treatment pages, and keep the FAQ schema markup in your website's code. The visual display feature in traditional Google search has been removed, but the format remains the most AI-citation-friendly content structure available.

Why Is Server-Side Rendering Now Non-Negotiable?

Recent confirmations show that AI crawlers are primarily text-only and often skip JavaScript entirely. If your website relies on client-side JavaScript to load its core clinical content, AI crawlers may see a blank page or incomplete information. Server-side rendering ensures that all your content is present in the initial HTML payload that the crawler receives.

This is no longer just a performance optimisation, it is a fundamental requirement for discoverability. If your condition pages, treatment pages, or practitioner profiles require JavaScript to render, they are effectively invisible to many AI search engines.

Frequently Asked Questions

Does the Perplexity update mean my clinic won't be cited anymore?

No, but it means the standard has been raised. Perplexity will still cite open-web sources for local or specific queries, but your content needs to demonstrate clear E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) signals, such as named clinician authors and inline citations, to be considered credible.

Should I delete the FAQ schema from my website?

Absolutely not. While Google is removing the visual rich result in traditional search, AI platforms still read the structured data directly. FAQ schema helps AI systems understand the structure of your content and extract answers efficiently.

How do I know if my website is server-side rendered?

The easiest way to check is to view the page source (right-click and select "View Page Source" or similar in your browser). If you can see your main text content in the raw HTML code, it is server-side rendered. If you only see a few lines of code and a lot of script tags, it is likely relying on client-side JavaScript.

What is the single most important thing I can do this month?

Ensure every clinical page on your site has a named clinician author with their credentials clearly stated, and ideally a link to their full bio page. Anonymous healthcare content is the first thing AI tools will deprioritise under these new, stricter quality frameworks.
