Mobile-first indexing means the mobile version is the version
Google predominantly uses the mobile version of your pages for indexing and ranking. That means if your mobile site is slower, stripped down, or missing content that lives on desktop, that weaker version is what Google evaluates, even for desktop searchers.
The most damaging and least visible problem is content parity: when the mobile version hides or omits text, images, or structured data that desktop has. We check that mobile and desktop tell Google the same story.
- Content parity: the same primary content, headings, and links on mobile as desktop
- Structured data and metadata present on the mobile version, not just desktop
- Whether responsive design, dynamic serving, or separate URLs is used, and its risks
- Images and media that load and are accessible on mobile
- Lazy-loaded content that Google can still discover and index
- Mobile version confirmed as the one Google is actually crawling
Usability and speed on real devices
Beyond parity, the mobile experience has to be genuinely usable. Tap targets too close together, text too small to read, content wider than the screen, and intrusive interstitials all hurt both users and rankings.
Speed matters most on mobile, where connections and devices are weaker. We evaluate your Core Web Vitals on mobile and identify what's slowing the experience down.
- Tap target size and spacing so buttons and links are easy to hit
- Legible font sizes and content that fits the viewport without horizontal scrolling
- Core Web Vitals on mobile: loading, interactivity, and layout stability
- Render-blocking resources and oversized images hurting mobile load times
- Intrusive pop-ups and interstitials that Google penalizes on mobile
- A prioritized fix list separating ranking-critical issues from polish

Frequently asked questions
My site is responsive. Doesn't that mean mobile SEO is handled?
Responsive design is the best foundation and solves a lot, but it doesn't automatically mean the mobile experience is fast, that tap targets are spaced well, or that Core Web Vitals pass on mobile. Responsive gets you most of the way; the audit checks the parts that still commonly fall short.
What's the single biggest mobile SEO mistake you see?
Content parity gaps on sites that serve a different mobile version. Content, links, or structured data that exists on desktop but is hidden or dropped on mobile. Since Google indexes the mobile version, that missing content effectively disappears from Google's view even for desktop rankings.
How is this different from just checking my page speed?
Page speed is one part of it, and an important one, but mobile SEO is broader. It also covers content parity, mobile usability like tap targets and readable text, intrusive interstitials, and confirming Google is crawling the right version. Speed alone won't catch a mobile page that's missing half its content.
