Extractability
Extractability is how easily an AI platform can lift a passage out of your page and use it in an answer, without the rest of the page around it.
Extractability is how easily an AI platform can take a passage from your page and use it in an answer on its own. A platform rarely quotes a whole page. It pulls out the few sentences that answer the question, so those sentences have to make sense without everything around them.
A page can be read, trusted and relevant, and still lose out if the answer is buried in a way that's hard to lift out.
What makes a passage easy to lift
Picture someone cutting a paragraph out of your page with scissors and handing it to a stranger. Does it still make sense?
It does when the paragraph names its subject instead of leaning on "this" or "it" from earlier on, when it gives the answer in its first sentence, and when the facts are written as text, in the page's HTML. It doesn't when the key point depends on a heading three screens up, a table that only loads after a script runs, or a picture with the price written on it.
An example
For example, compare two answers to "How much is a Fernhill Coffee subscription?"
"As mentioned above, it starts from there, depending on the plan you pick." That needs the rest of the page to mean anything.
"A Fernhill Coffee subscription costs £12 a month for 250 g, with free UK delivery." That works wherever it's quoted.
How to check yours
Read the opening of each section on its own. Look at the page with scripts turned off, or the way a bot reads it, and see whether the answer is still there. Put the question someone would ask in a heading, and the answer straight after it.
In AnswerOrbit, Page checks look at a page for a prompt, including whether it's shown without scripts, whether the prompt is in a heading and whether it opens with an answer. The Pages tab in Website shows What a person sees next to What a bot reads, and marks blocks that are Hidden from bots.
