Performance and Duplication
Page Experience Signals What Google Measures Beyond Speed
Beyond Core Web Vitals, Google's page experience signals include mobile-friendliness, HTTPS security, and the absence of intrusive interstitials, all of which affect how comfortably a user can actually consume a page.

Google indexes and ranks the mobile version of a page under mobile-first indexing, meaning the content, structured data and links present on the mobile version are what determine rankings, even for desktop searches. A responsive layout that reflows correctly, text that is legible without zooming, tap targets spaced with adequate gaps, and no horizontal scrolling are baseline requirements rather than optional refinements.
Ensure the mobile version of a page contains the same content, headings and structured data as the desktop version; a stripped-down mobile version that omits content present on desktop can directly reduce what Google is able to index for that page.
HTTPS and security signals
HTTPS has been a baseline ranking signal for years, and browsers now actively warn users when a page collecting input, such as a login or payment form, is served over unencrypted HTTP, which damages trust and conversion regardless of any ranking effect. Ensure the entire site, including all subdomains and resource files, loads over HTTPS with a valid, unexpired certificate, and that no mixed content, HTTP resources loaded on an HTTPS page, triggers browser warnings.
Intrusive interstitials
Google's guidance specifically penalises mobile pages that show an intrusive pop-up covering the main content immediately on arrival from a search result, since it degrades the experience the searcher expected. Legally required interstitials such as age or cookie-consent notices, and small, easily dismissible banners, are exempted, but a full-screen email signup or app-download overlay blocking the content is not.
If a promotional interstitial is necessary, delay its appearance until after the user has had a chance to engage with the content, and ensure it is easily dismissible with a clearly visible close control.
- Ensure mobile content and structured data match desktop exactly
- Serve the entire site over valid HTTPS with no mixed content
- Avoid full-screen interstitials immediately on page arrival
- Make any necessary overlay small, delayed and easily dismissible
Checking page experience in RankAudit
RankAudit's Page Experience report checks mobile usability issues, HTTPS and mixed-content errors, and flags pages where an interstitial was detected during the mobile crawl simulation. Treat any HTTPS or mixed-content flag as urgent, since it affects user trust immediately and is usually a quick server-configuration fix.
Key takeaways
- ✓Mobile-first indexing means the mobile version is what gets ranked
- ✓Match content and structured data across mobile and desktop
- ✓Serve the whole site over valid HTTPS with zero mixed content
- ✓Avoid intrusive interstitials on arrival from search results
