Question 1 of 6 / Read

What an answer engine reads on your page.

The short version is: less than a browser does. Here is what the crawlers themselves say, and how to see your HubSpot page the way they see it.

THE SHORT ANSWER

What does an answer engine read on a HubSpot page?

Mostly the HTML your server sends: the text, the headings, the links and any structured data in it. Several AI crawlers do not run JavaScript, so anything a script adds after the page arrives may never be read.

Pages built from HubSpot's HubL templates arrive with their text in the HTML. Content a module loads with a script later does not, so check yours with the steps below.

The rise of the AI crawler

01 / On HubSpot

Read your page
the way a crawler does.

Five checks, a few minutes each, on any page of your site.

  1. 01

    View the source, not the page

    Open the page, press Ctrl+U (Cmd+Option+U on a Mac) and search for the first sentence of your answer. If it is not in the source, a crawler that does not run scripts will not see it.

    Leave with Whether the answer is in the HTML

    StudyWhich crawlers run JavaScript
  2. 02

    Switch JavaScript off

    In Chrome DevTools, press Ctrl+Shift+P (Cmd+Shift+P on a Mac), run Disable JavaScript and reload. What is left is close to what a crawler without a browser reads.

    GuideChrome: disable JavaScript
  3. 03

    Unfold what is folded

    Tabs, accordions and sliders often hold text until someone clicks. Keep the answer itself in the open and use folds for detail, because a system that renders the page may skip what is hidden.

    Leave with The answer outside any fold

  4. 04

    Put the answer first

    Bing asks for essential information near the top and no long introduction. On HubSpot that means the first module under the header states the page's question and answers it.

  5. 05

    Check the page may be shown

    Google's AI features use pages that are indexed and eligible to be shown with a snippet. In the source, search for noindex and nosnippet; neither should be on a page you want quoted.

    Leave with No tag that keeps the page out

02 / The evidence

What the crawlers
and engines say.

Each card quotes the organisation or the study, with the date the page shows.

01 / JAVASCRIPT

Most AI crawlers do not run JavaScript.

Vercel and MERJ watched the major AI crawlers on Vercel's network and wrote: "none of the major AI crawlers currently render JavaScript." Gemini and Applebot were the exceptions.

Last reviewed 24 September 2026

Why this matters

The study is from December 2024 and covers traffic on Vercel's network. We found no newer study of the same standing, so read it as the best evidence, not the last word.

02 / TRAINING DATA

Common Crawl does not run scripts.

Common Crawl's own FAQ: "Currently, JavaScript is not executed and Cookies are not used."

Why this matters

Common Crawl builds an open archive of the web. Vercel describes it as often used to train language models; Common Crawl does not describe itself that way. The FAQ shows no date.

03 / GOOGLE

Google needs a page it can show.

Google: "There are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary." A page must be indexed and eligible to be shown with a snippet.

Why this matters

Google adds that it "is able to process content within JavaScript as long as it isn't blocked", in its AI optimisation guide, last updated 10 July 2026.

04 / BING

Bing asks for the answer early and in the open.

Bing's guidelines: "Place essential information near the top of the URL", and avoid "Hiding critical content behind client-side rendering".

03 / Questions

Fair questions,
straight answers.

What people ask about crawlers and their pages.

Does HubSpot send my text in the HTML?

For pages built from HubL templates, yes: the text of drag and drop modules is in the HTML the server sends. A module that fetches its content with a script after the page loads is the exception. View source is the quickest way to tell.

Is text inside a closed accordion read?

If the module writes it into the HTML, a crawler that reads the source can see it. But Microsoft notes that "AI systems may not render hidden content, so key details can be skipped." Keep the answer outside the fold and put the detail inside.

Does Google read JavaScript?

Google says it "is able to process content within JavaScript as long as it isn't blocked." In Vercel's study, Gemini and Applebot rendered JavaScript and the other major AI crawlers did not.

Do I need special AI markup or files?

Not for Google. Its guide: "You don't need to create new machine readable files, AI text files, markup, or Markdown to appear in Google Search (including its generative AI capabilities), as Google Search itself doesn't use them." Questions 2 and 4 of this guide go further.

Is there a switch in Search Console for AI features?

Yes. Google: "a site must be included in Search generative AI features in Search Console to be eligible for display in generative AI features on Google Search." Including is the default for every property, and the control reached every site on 31 August 2026.
