What the inspection does not measure.
A good measuring tool tells you its limits before you trust it. Every item on this list is a limit: something the tool cannot see, even where it runs a check close by. We would rather you know that before you run it than find out after.
We read one page, not your whole site
The free inspection reads the address you enter, unless that site has asked us to stay away. It does not crawl every page, follow internal links, or check whether other pages pass. A home page can pass while a contact page or a product page fails.
We read what the server sends, not what a real phone shows
The check fetches the page's HTML, the code the server sends, and does not run its scripts. Scripts are the small programs that change a page after it loads. It cannot see the screen. A site can carry the viewport tag, the one line we check that tells a phone how wide to draw the page, and still be hard to use on a small screen.
When we pass a phone-layout check, we are saying the technical signal is there, not that the site looks right on a phone.
We measure speed signals, not speed itself
We check server response time and page size, how big the HTML is as the server sends it. These are inputs to load time, not load time itself. We say what we measured; we do not say the site loads fast.
We check whether structured data is present and valid, not whether Google shows it
Structured data means labels in the page's code that hand search engines facts like your hours and address. Adding it makes your content eligible for richer search features. Google decides whether to show them, and it says the choice depends on things we cannot see, such as the searcher's location, device and past searches.
A pass on the structured data check means those labels are present and well-formed. It does not mean your listing will show hours or a map pin.
We check contact signals, not whether messages arrive
We check whether a contact path exists on the page: a form, an email or phone link, or a link to a contact page. We do not send a test message through the form.
A form that passes the check can still deliver to an inbox nobody reads, or to an email address that bounces. Proving delivery is a separate test.
We read public pages only
We read only public pages, the ones anyone can open without signing in. Pages behind a login, a checkout, a booking step, or a challenge wall (a screen that asks visitors to prove they are human) are not read. A challenge wall returns as a refusal, which we say openly rather than guessing.
We do not audit ad accounts, analytics, or reputation
This tool reads your website, not what is happening around it. How well your ads spend and what your analytics report live inside your own accounts, so anyone who claims to audit them from outside has guessed. Reviews are public, but reading them is a different job, and this tool does not do it.
We measure a site as it stood when we fetched it
A site changes. The check you run today reports what the server returned today. A change made after the check is not in the report. Run the check again after a fix, and the new report reflects the fix.
A passing score is not a sales guarantee
A site that passes every check is technically sound. Whether customers find it, call from it, and buy depends on what they find when they land, who is sending them there, and whether you are the answer to the question they asked. We measure the site. We do not measure your market.
What the tool does measure is on the inspection page itself. Run it on any public website that has not asked us to stay away and the report names every check, what it found, and what a failure costs.
