What can only be read from outside the browser?
The readings a browser is not allowed to make, taken from our infrastructure instead.

Every reading in this tab makes a request from our infrastructure rather than from the browser, and that is a different promise from the rest of the product. A promise that holds on one screen and not the next is not a promise, which is why these sit together behind one sentence instead of being scattered through SEO and Tools where each of them would otherwise belong. What they buy is what a browser is not permitted to fetch on your behalf: the page as a crawler receives it, the response before any consent banner has run, and what the site serves to somebody asking for it in another language.
