Why it matters.
Crawlers that do not run scripts read the raw HTML. If a consent tool or gate replaces your content on the server, or a bot challenge answers instead of the page, that is what gets read. Google’s guidance is direct: “Don’t obscure the entire page with interstitials” and “Don’t redirect the user to a separate page for their consent or input” (read 8 November 2026).
We grade this Early: no study yet measures pop-ups and AI citations directly. The checks are cheap, and the same walls cost human enquiries.
The 10-minute self-check.
On your three most important pages:
- Open each in a private window. What covers it before you click anything?
- Fetch the raw HTML (curl, or view source). Is the main text there, or a consent or challenge page?
- Is anything buyers ask AI about, such as your method, results or pricing approach, behind a form?
Steps.
- Use a consent banner, not a full-page wall, and make sure it never removes content from the HTML.
- Exempt verified search crawlers from bot-challenge pages in your CDN or firewall.
- Ungate the facts. Keep case-study summaries and your method public; gate only the extras such as templates and full PDFs.
- Delay pop-ups and chat prompts until a visitor has engaged; never cover the page on load.
- Re-test after any change to your consent tool, CDN or security settings.
These checks are part of our conversion rate optimisation reviews, because the same walls stop human enquiries.

How to measure it.
- Raw HTML check: pass or fail per key page, after every change.
- Crawler status codes: monthly (play 26).
- Human signal: engaged sessions and key events on pages where you removed a wall.
