PDP Health Check: A Free Chrome Extension to Audit Product Pages for SEO and AI Search
Short version: PDP Health Check is a free Chrome extension from Magenable that audits any ecommerce product details page in one click. It checks the structured data, metadata, and price/stock signals that both Google and AI shopping engines read — and flags the gaps most product pages have without anyone noticing. You can install it from the Chrome Web Store here.
The product page is where ecommerce search is quietly won or lost
For most online stores, the product detail page (PDP) is the single most important page. That is where significant share of the traffic lands, the buying decision happens, and it’s the page search engines and AI assistants lean on most heavily to understand what you actually sell.
The problem is that the things determining whether a PDP can be read by a machine are mostly invisible in the browser. The page can look perfect to a shopper while the Product schema is missing, the price in the HTML doesn’t match the price in the structured data, or the meta description is quietly blank. You don’t see any of it until you open view-source and go hunting.
We’ve done that hunt hundreds of times for clients. PDP Health Check is the tool Magenable built so you don’t have to.
Why this matters more in the AI/GEO era
Classic SEO already cared about clean product markup. Generative engines have raised the stakes.
AI shopping tools increasingly pick what to recommend based on whose product data is clean and machine-readable. When Profound tracked ChatGPT Shopping, the share of recommendations drawn from merchants’ integrated product feeds jumped from 8% to 62% almost overnight on 10 July 2026, and reached about 65% by September. Recommendations also concentrated onto fewer merchants: the top 10 stores’ share of references rose from 22.5% to 41.8% (Profound). Google’s AI Overviews, meanwhile, take clicks away from the results below them. Seer Interactive found organic click-through on informational queries fell 61% when an overview appeared (2025 study). It has recovered somewhat since, but in February 2026 it was still 2.4%, against 3.8% for queries without an overview (2026 update).
The throughline: the page’s structured data is becoming its résumé for machines. Generative Engine Optimization (GEO), making your content legible and quotable to AI engines — starts with the same unglamorous fundamentals that good SEO always did. Accurate Product and Offer markup. Prices and availability that agree with what’s on screen. Titles, descriptions, and variant labels a model can parse without guessing.
If a machine can’t read your PDP cleanly, it increasingly just recommends the competitor it can read.
What is PDP Health Check?
PDP Health Check by Magenable is a free Chrome extension (currently version 0.2.0) that runs an on-demand diagnostic on whatever ecommerce product page you have open. You open a product page, click the extension icon, and choose Analyse This Page in the side panel. It reads the page only when you trigger it, scores what it finds, and hands back prioritized, plain-language findings.
It’s free, needs no account or registration, and is built privacy-first: it does not upload page HTML or product data to Magenable or to any third-party AI service.
What it checks
In a single pass, PDP Health Check looks at:
- On-page SEO signals — page title, meta description, headings, canonical URL, and robots declarations.
- Structured data —
ProductandProductGroupJSON-LD, plus a supported subset ofProduct/Offermicrodata. - Commercial consistency — price, currency, and availability, including whether the visible price and stock match what’s declared in the structured data (a surprisingly common mismatch).
- Content and conversion readiness — product images, purchase controls, variant labels, and whether delivery and returns information is accessible.
- Basic page observations — local image and DOM checks.
Results come back as category scores with evidence coverage, confidence levels, prioritized findings, and recommendations. Anything it can’t verify is marked Not Evaluated rather than quietly passed or failed — so you’re never misled into thinking a gap is covered when it isn’t. Reports can be copied or exported as text or JSON.
How to use it (about 30 seconds)
- Install PDP Health Check from the Chrome Web Store.
- Open any product page — yours or a competitor’s.
- Click the extension icon and select Analyse This Page in the side panel.
- Read the category scores and prioritized findings; export the report as text or JSON if you want to share or track it.
That’s the whole loop. It’s designed to be the five-minute triage you run before a deeper audit, not a report you wait on.
Privacy by design
Because the tool reads live pages, I was deliberate about what it’s allowed to touch. PDP Health Check reads the page only when you click to analyse it. It does not upload page HTML or product data anywhere, it doesn’t request browsing history, cookie, or blanket site-access permissions, and reports are cached only temporarily in your browser session. In short: the analysis happens in your browser, and it stays there.
What it deliberately doesn’t do
I’d rather undersell this honestly than oversell it. PDP Health Check is a fast first look, not a complete audit. It is not a full SEO, rich-results, accessibility, mobile-UX, performance, or inventory audit. Custom markup, hidden content, and ambiguous product variants can limit how much it can verify. Its AI-discoverability signal reflects content readiness – whether the page is structured to be read, not your actual rankings or whether an AI engine currently cites you.
Its findings don’t guarantee improvements in search, conversion, or sales. They point you at fixable gaps faster, so your real optimization time goes to the right places.
Who it’s for
It’s built for the people who touch product pages: ecommerce managers, SEO specialists, developers, and agency teams who need to spot PDP gaps quickly, before committing to a deeper structured-data or technical-SEO project. It’s just as useful for a fast competitive teardown as it is for auditing your own catalog.
FAQ
Is PDP Health Check free?
Yes. It’s free, with no account or registration required.
Does it send my data anywhere?
No. It reads the page only when you trigger an analysis and does not upload page HTML or product data to Magenable or any third-party AI service.
What does it actually check on a product page?
Metadata (title, meta description, headings, canonical, robots), Product/ProductGroup structured data, price/currency/availability consistency between the visible page and the markup, and content-readiness signals like images, variants, purchase controls, and delivery/returns information.
Will it fix my product pages or guarantee rankings?
No. It diagnoses and prioritizes issues; the fixes and the results are up to you. It’s a triage tool, not a promise.
How is this related to GEO (Generative Engine Optimization)?
AI shopping engines read structured product data to decide what to surface. PDP Health Check checks whether that data is present, consistent, and clean — the groundwork GEO depends on — though it measures readiness, not live AI visibility.
