What does Metryn scan?
One page: the address you type in, plus the site-wide signals that apply to it.
Alongside it Metryn reads the site-wide technical signals that apply to that page: robots.txt, the sitemap, the HTTP response headers and the structured data (JSON-LD) in the page.
If the page looks like a product page, the paid report also reads its Product structured data from the HTML (price, currency, availability) and notes what is wrong or missing. That part never changes the score, and it can only read what is in the HTML the server sends, not prices that scripts add later.
It is not a crawl of your whole site. Other pages are not read, so a problem that only exists on a page you did not enter will not show up.
What does the score mean, and what does it not mean?
A number from 0 to 100 for the technical checks. It is not a forecast.
The score sums up the technical checks: crawler access, indexability, sitemap and structured data, and how clear the content is in the raw HTML. The weights and every rule are public.
A low score means something technical is in the way of a machine fetching or reading the page. A high score means the checks found nothing in the way. It does not predict rankings, traffic or whether any AI assistant will mention you, and Metryn does not promise any of that.
Does Metryn check what ChatGPT or Perplexity actually do with my site?
No. It does not ask any AI product anything.
For each crawler it reads the rules in your robots.txt and applies the crawler's published user agent name to them, and it fetches your page once the way an ordinary external client would.
That tells you what your own rules allow and what a standard request can read. It does not prove how a given company's crawler behaves today, and the report labels the access check as simulated.
Do I need an account?
No. The scan, the result and the free tools work without signing up.
Buying the report does not create an account either. After you pay you get a private link to your report instead of a login.
What do you store, and for how long?
A scan keeps the address, the score and the findings with short evidence snippets. The full HTML of your page is never stored. A scan that was never paid for is deleted 12 months after it was made; a paid report is deleted 24 months after the purchase, and its link then stops working.
Each scan also keeps a small snapshot of what the scanner read (title, description, first heading, labels for any Shopify markers it saw, and the first 500 characters of visible text). It is removed 90 days after the scan. When a paid report is opened, your robots.txt and sitemap are fetched again to draft its paste-ready files; that text is not stored. Your IP address is never written to the database; a keyed hash of it is kept on the scan to limit abuse and is removed after 90 days. If you join the monitoring waiting list, the email address you type is deleted after 90 days. If you send feedback through the feedback page, it is published only if you consent and we approve it; an approved quote is deleted 24 months after approval and an unapproved one after 90 days.
The privacy policy has the complete table, including what Paddle and the web server logs hold.
What happens if my site uses a firewall or a bot challenge?
The scan stops and says so, instead of scoring a challenge page.
If the page answers with a bot-verification page, the scan stops and says so instead of scoring the challenge page. The message says the result tells nothing about your policy for AI crawlers, because the scanner never saw your real page.
If robots.txt or the sitemap answer with an error or a timeout, the finding says it could not be read, deducts no points and does not claim the file is missing. You can allow the MetrynScanner user agent in your firewall and scan again.
How long does a scan take?
Usually a few seconds, and up to about a minute for a slow site. A scan is cut off after a minute and reported as failed rather than left hanging. Several scans can be queued at once, so a busy moment can add a short wait.
Can I scan the same site again after I fix something?
Yes, but give it a moment: the same address within 15 minutes returns the finished result.
If the same address was scanned within the last 15 minutes, you get that finished result again instead of a new fetch of your site, so wait a little after a change before you re-run it. Limits apply: 10 scans per hour from one network and 3 per hour for any one domain, shared by everyone.
Each scan is its own result with its own free preview. A purchase unlocks the report of the scan it was made for. There is no before-and-after comparison between two scans yet.
How do I pay, and how do I get the report?
From the result page, through Paddle. The report unlocks once payment is confirmed.
Paddle is the merchant of record: it takes the payment, handles tax and sends the receipt, and Metryn never sees your card details. Once Paddle confirms the payment the report unlocks.
Paddle gives us the email address you used at checkout and we send one email there with the private link to your report. If it does not arrive, check your spam folder and then write to us with the address you scanned.
Can I get a refund?
Yes: a 30-day money-back guarantee on the full report.
Metryn offers a 30-day money-back guarantee on the full report, except in reasonably clear cases of abuse or fraud. Email us within 30 days of the purchase and we ask Paddle to refund the order. We will not ask you to justify the request beyond identifying the purchase.
This is in addition to your statutory rights, which go through Paddle.
How is this different from Search Console or an SEO suite?
Search Console shows Google's own data. Metryn checks whether crawlers can read any public page.
Search Console shows what Google itself recorded about a site you have verified: what it indexed, which queries brought visits, which errors it hit. Metryn cannot see any of that. In exchange it works on any public address without verification and looks at one narrow thing, whether crawlers, including AI crawlers, are able to fetch and read the page.
SEO suites cover keywords, backlinks and rank tracking. Metryn does none of that, and a free single-purpose checker may be enough if all you need is a quick look at robots.txt.
Who runs Metryn, and how do I get in touch?
Metryn is operated by Gonçalo Torres, as a single-person project. There is no team and no agency behind it, so replies come from one person.
Write by email, using the Contact link in the footer. That address is also where refund requests, bug reports and requests to delete your data go. Include the address you scanned and, for a purchase, the email you used at checkout.
