Key takeaways
- A free Shopify AI SEO audit should read the live page, not ask for collaborator access.
- Focus on structured facts, crawler access and llms.txt — not a vanity AI score.
- Fix the page type you pasted: product markup for products, WebSite for the homepage.
- Use the ChatGPT SEO check for Shopify stores when you want that list in under a minute.
- The public check is free and rate-limited, with no credit card; it names gaps, it does not edit the theme.
You do not need another paid “AI SEO” retainer to learn if your Shopify store is readable to models. You need a free Shopify AI SEO audit that reads the public page and returns a punch list you can staff. Open the ChatGPT SEO check for Shopify stores, paste any storefront URL, and fix schema gaps, blocked AI bots and a missing llms.txt before you rewrite another product description.
What a free Shopify AI SEO audit should be
It should read the live page. It should not ask for collaborator access. It should not hide the findings behind a sales call. Focus on structured facts, crawler access and llms.txt — not a vanity “AI score” nobody can verify.
The public check on ninety9.dev is free and rate-limited. No credit card. It names what is missing so you or your developer can fix the theme, SEO app or robots.txt. It will not edit the theme for you.
Agencies may use it only on stores they are authorised to check. Merchants can opt out with a meta tag.
Why “AI SEO” audits fail merchants
Agencies ship 40-page decks that mix Core Web Vitals, backlinks and “write for ChatGPT” fluff. You leave with homework and no single next click.
A useful free Shopify AI SEO audit is shorter: can a model fetch this URL, and are the facts on the page marked up so it does not guess? Keep Google Search Console for indexing and queries. This check does not replace it.
If you also care about the buy button, that is a different pass — the CRO Audit looks at what stops the sale on a product page. Do not mix the two punch lists in one ticket.
What to check before you rewrite copy
Rewriting descriptions when the product has no Product JSON-LD is theatre. Unblocking GPTBot when the page is noindex is theatre. Publishing llms.txt while Organization markup is missing is incomplete.
Order of work for most stores:
- Indexable page (no accidental noindex)
- Consistent name / title / OG
- Structured data for that page type
- robots.txt allows the AI crawlers you care about
- Optional llms.txt
Fix the page type you pasted: product markup for products, WebSite or Organization for the homepage. A green homepage does not prove the PDP is clean.
How to run the free check
- Open the ChatGPT SEO check for Shopify stores.
- Paste yourstore.com or any Shopify page. No login. https:// is optional.
- If the store is password-protected, paste the storefront password when asked.
- Read the fails top to bottom. Each row is a merchant-facing outcome: “price missing in markup,” “GPTBot blocked,” “no llms.txt.”
- Copy reds into your tracker with the URL and date.
- Ship the theme or robots change. Re-paste the same URL.
- Use the ask-assistant buttons and compare the answer to the live page.
Full click-path: how to run the Shopify SEO & AI Audit. For what the tool is and is not, see what the ChatGPT SEO check actually is.
Worked example: you are about to rewrite 40 product descriptions. You audit one bestseller first. Offer fails and GPTBot is Disallowed. You stop the copy sprint, unblock the crawler, restore Offer, re-audit, then rewrite. The descriptions now sit on a page a model can actually quote.
What “good enough” looks like
You do not need a perfect score to ship. You need the page type’s essentials:
- Product: name, image, price, availability
- Homepage: shop identity and a way into the catalogue
- robots.txt: does not silence the bots you care about
- llms.txt: ideally present and useful, not empty fluff
Schedule optional rows (missing llms.txt, extra FAQ markup) behind the gates. Discovery without readable markup is still a hobby.
What you should walk away with
A useful free audit ends in a staffed list, not a feeling. You should have:
- Four URLs checked (home, collection, product, policy)
- Reds copied into tickets with an owner
- A crawler policy written in one paragraph (allow or deny GPTBot and the others on purpose)
- A date to re-run after the theme or robots change ships
Optional: a short llms.txt draft sitting with marketing until /llms.txt is live.
You should not walk away with a promised “AI ranking,” a collaborator request, or a 40-page deck. If a vendor will not show you the live-page fails before the contract, they are selling anxiety.
Common mistakes
- Paying for a retainer before a free public-page pass
- Auditing a preview theme you will not publish
- Treating the list as a citation rank
- Letting an agency run it on stores they do not have permission to check
- Rewriting all product copy while Offer markup and robots.txt are still red
After the list is green enough to ship, ask ChatGPT about the same product URL. If the answer is still wrong, you have a staleness or third-party-source problem — but you have already removed the excuse that your own page was unreadable.
Run the free audit once before the next content sprint. Paste the homepage and a bestseller, ticket the reds, and only then rewrite — discovery without readable markup is still a hobby.
Frequently asked questions
Is the Shopify AI SEO audit free forever?
The public check on ninety9.dev is free and rate-limited. No credit card. Use it on the URLs you are authorised to check; merchants can opt out with a meta tag.
Will it fix my theme for me?
No. It names what is missing so you or your developer can fix the theme, SEO app or robots.txt. Copy failing rows into a ticket; re-run the same URL after you ship.
Does it replace Google Search Console?
No. Keep Search Console for indexing and queries. This check is for AI-readable markup and crawler rules on the URL you paste.
Can agencies use the free audit on client stores?
Only on stores you are authorised to check. Merchants can opt out with a meta tag. Treat it as a public-page review, not a backdoor into admin.
What is a free Shopify AI SEO audit?
It is a public-page pass/fail of whether models can fetch and understand a live Shopify URL: structured data for that page type, AI crawler rules in robots.txt, and optional llms.txt. It should not require collaborator access or a paid retainer to learn the basics.
Which URL should I audit first?
Paste the homepage for shop identity, then a bestseller for price and availability markup. Add a collection and a policy page before you rewrite copy. Each page type has different essentials.
What does “good enough” look like?
You do not need a perfect score to ship. You need the page type’s essentials: a product with name, image, price and availability; a homepage with shop identity; robots that do not silence the bots you care about; and ideally an llms.txt that points models at your best pages.
