Glossary of AI and Search Exposure Signals

Every term here is something the inspection actually reads on a page, defined in plain language with the part a short definition leaves out. If a finding in your result used a word you did not recognize, it is defined here.

29 terms. Updated .

A

  • AI Crawler

    An automated client operated by an AI company that fetches pages for training data or live answer retrieval.

  • Anchor Text

    The visible words inside a link, which describe the destination to anything that cannot see the page.

  • Answer-First Paragraph

    A self-contained answer placed in the first paragraph after the H1, before any explanation or setup.

  • App Shell

    A near-empty HTML document containing a single mount element that script later fills with the real content.

B

  • Boilerplate Ratio

    How much of a page response is actual readable text compared with markup, script, and embedded data.

C

  • Canonical URL

    A declaration naming which URL is the real address of a page, so duplicate variants do not compete with each other.

  • Client-Side Rendering

    Building page content in the browser with JavaScript after the server has already sent its response.

D

  • Discovery Signal

    Anything observable that affects whether a machine can reach a page at all, before any question of quality comes up.

E

  • Entity Consistency

    Using one name, one spelling, and one identity for a publisher across every signal a page emits.

F

  • FAQPage Markup

    Structured data that pairs a question with its answer explicitly, rather than leaving the pairing implied by layout.

  • Freshness Signal

    A visible or declared date telling a reader and a machine when a page was published or last revised.

H

  • H1

    The single top-level heading that states what a page is about.

  • Heading Hierarchy

    Heading levels used in descending order so the page has a readable structure rather than just styled text.

I

  • Inspection Score

    A 0 to 100 weighted result showing how much of the observable signal set a page actually carries.

  • Internal Link

    A link from one page of a site to another, present in the HTML response rather than added by script.

  • Investigate Finding

    A signal that looks wrong from outside but has a legitimate explanation an external inspection cannot rule out.

L

  • llms.txt

    A plain text file at the site root describing what a site covers and which pages matter most, written for AI clients.

N

  • noindex

    A directive, in a meta tag or an HTTP header, telling search systems to keep this page out of their index.

O

  • Open Graph

    A small set of meta tags stating a page title, description, image, and URL in a second, redundant form.

P

  • Publisher Entity

Q

  • Quick Fix

R

  • Redirect Chain

  • Semantic Landmark

    An HTML element that marks where the primary content of a page begins and ends.

  • Stable Identifier

    A durable URI given to a node in structured data so other nodes can reference it instead of repeating it.

  • Structural Issue

    A finding whose cause sits above the page, in the architecture, rendering model, or hosting, and cannot be fixed by editing content.

  • Structured Data

    Machine-readable statements embedded in a page describing what it is and who published it.

X

    A machine-readable list of the URLs on a site that its owner wants crawled.
