Does my website need to be mobile-friendly to show up in AI search?
Practically, yes. Google uses the mobile version of your content for indexing and ranking, and AI Overviews draw on pages that are indexed and eligible to show a snippet. Google says a mobile-friendly site is very strongly recommended, though not required, and that the mobile and desktop versions should have the same content.
What this means
Mobile-first indexing means Google looks at the mobile version of your page when deciding what is on it. If the phone version has less content than the desktop version, Google sees the smaller one.
Google's guidance says to make sure the mobile site contains the same content as the desktop site, to keep headings and structured data equivalent, and to avoid lazy-loading primary content behind user interactions. It says mobile-friendly sites are very strongly recommended, but not required for inclusion in results (Google Search Central, 2025b).
Because Google says AI Overviews and AI Mode have no extra technical requirements beyond being indexed and eligible to appear with a snippet (Google Search Central, 2025a), the mobile version is effectively the version that counts.
Who this applies to
Any business whose site was designed on a desktop first, uses a separate mobile site, or hides content on small screens to save space.
How we'd evaluate it
We compare the phone and desktop versions of key pages:
- Content parity. Is every important paragraph, price, and service on both versions?
- Headings and structured data. Do both versions carry the same ones?
- Hidden content. Is anything removed or loaded only after a tap on mobile?
- Readability. Are paragraphs and sections broken up so text is easy to read?
Available options
- Use responsive design. Google recommends serving the same HTML on the same URL.
- Match the content. Add missing mobile content rather than hiding desktop content.
- Keep structured data equal. Use the same markup on both versions.
- Check in Search Console. Verify the mobile version is indexed and renders correctly.
Benefits, limitations, and tradeoffs
Matching content can make mobile pages longer. Accordions are one option Google mentions for keeping them tidy. A rebuild of an old non-responsive site costs real money, so check how bad the gap is first.
What we know
Google states it uses the mobile version for indexing and ranking and recommends matching content, headings, and structured data across versions (Google Search Central, 2025b). Google's starter guide also advises breaking long content into paragraphs and sections (Google Search Central, 2025c).
What we don't know: whether AI products other than Google's apply a mobile-first approach. Their documentation does not say.
Next steps
Open your five most important pages on a phone and on a laptop, side by side. Write down anything missing on the phone. Fix those gaps first.
Orlando considerations
Visitors and residents search for Orlando businesses on their phones, often while out. A site that hides hours, directions, or prices on mobile fails them and, per Google, may be indexed without them.
