Mobile SEO Checklist: Automated SEO Workflow

Overview

Google uses mobile-first indexing for all sites. If your mobile experience is subpar, your rankings suffer regardless of how well your desktop site performs. This checklist covers every aspect of mobile SEO from technical foundations to content parity.

Technical Foundation

• Verify your site uses responsive design (single URL serving all devices)
• Confirm the viewport meta tag is set correctly: <meta name="viewport" content="width=device-width, initial-scale=1">
• Test that no horizontal scrolling occurs on any page template at 375px width
• Ensure text is readable without zooming (minimum 16px base font size)
• Verify tap targets are at least 48x48px with adequate spacing between them
• Check that no content is hidden behind “read more” toggles that differ from desktop
• Confirm all structured data present on desktop is also present on mobile
• Validate that canonical tags are consistent between mobile and desktop versions

Content Parity

• Verify all primary content visible on desktop is also visible on mobile
• Check that heading tags (H1, H2, H3) are identical on mobile and desktop
• Confirm all images have alt text on both versions
• Ensure internal links present on desktop are also present on mobile
• Validate that lazy-loaded content is accessible to Googlebot (use intersection observer, not scroll events)

Page Speed on Mobile

• Test mobile page speed on a throttled 4G connection (not just WiFi)
• Verify LCP is under 2.5s on mobile devices
• Check that INP is under 200ms on mobile
• Confirm CLS is under 0.1 on mobile (layout shifts are more impactful on small screens)
• Ensure images are served at appropriate sizes for mobile viewports (not desktop-sized images scaled down)
• Verify critical CSS is inlined so above-the-fold content renders quickly on slow connections

Navigation and UX

• Test that the mobile menu is accessible and functional
• Verify all dropdown menus and accordions work on touch devices
• Check that forms are usable on mobile (appropriate input types, auto-complete attributes)
• Ensure pop-ups and interstitials comply with Google’s intrusive interstitial guidelines
• Confirm that sticky headers do not consume more than 15% of the mobile viewport
• Test that back-button behavior works correctly after navigating internal links

Local and Voice Search

• Verify click-to-call phone numbers use tel: links
• Ensure address information is crawlable text (not embedded in images)
• Check that Google Maps embeds load correctly on mobile
• Confirm FAQ schema is implemented for content likely to appear in voice search results

Testing and Validation

• Run Google’s Mobile-Friendly Test on representative URLs from each template
• Test on at least three real devices: a recent iPhone, a mid-range Android, and a tablet
• Use Chrome DevTools device emulation to test additional screen sizes
• Run Auditite’s mobile audit to catch issues across your entire site programmatically
• Review Google Search Console’s Mobile Usability report for flagged issues

Common Mobile SEO Mistakes

Blocking CSS or JavaScript

If your robots.txt blocks CSS or JS files, Googlebot cannot render your mobile page correctly. Always allow crawling of all resources needed for rendering.

Different Content on Mobile

Hiding significant content on mobile (even with CSS display:none that is device-conditional) can cause Google to miss that content during indexing. Content parity is essential.

Unoptimized Mobile Images

Serving 2000px-wide images to a 375px-wide viewport wastes bandwidth and slows rendering. Use responsive images with proper srcset breakpoints.
