Google’s mobile-first indexing means your mobile site is now the primary version used for crawling and ranking. If your desktop site is perfect but your mobile experience is broken, bloated, or incomplete—you’re at risk of falling behind.
Mobile-first indexing isn’t just about having a responsive layout. It requires that your content, structure, performance, and user experience are optimized specifically for mobile devices.
The good news? You don’t have to figure it out alone.
With AI-powered tools like DIYSEO GPT, you can run precise, Google Search Console-driven audits, uncover hidden mobile indexing problems, and take action using insights from enterprise-grade, pre-written prompts.
This guide breaks down how to:
- Use AI to identify mobile-first indexing issues
- Align content and structure between mobile and desktop
- Leverage DIYSEO GPT prompts like Mobile Performance, Indexation Overview, and Top Exclusion Reasons
- Adapt on-page elements with SEO AI Writer
- Promote mobile-optimized pages using Link Marketplace
What Is Mobile-First Indexing?
Mobile-first indexing means Google uses the mobile version of your site—not the desktop version—as the primary source for:
- Crawling
- Indexing
- Ranking
If your mobile experience lacks content, internal links, metadata, or schema that your desktop site has, those gaps will directly hurt your organic performance.
Mobile-First Indexing Affects:
- Page ranking
- Crawl efficiency
- Indexing speed
- Rich snippet eligibility
- Core Web Vitals scores (which are mobile-weighted)
What Mobile-First Optimization Really Requires
To succeed with mobile-first indexing, your mobile experience must match (or exceed) your desktop in key areas:
| Area | Mobile-First Requirement |
|---|---|
| Content | Same headlines, body copy, and internal links as desktop |
| Metadata | Titles, descriptions, and schema should be consistent |
| Navigation | Easy-to-use mobile menus and link visibility |
| Indexing | Mobile URLs should be crawlable and included in your sitemap |
| Speed | Pages should load in under 3 seconds on 4G connections |
| UX | Tap-friendly buttons, readable fonts, clean layout |
How AI—Specifically DIYSEO GPT—Supports Mobile-First Optimization
DIYSEO GPT is built differently than traditional SEO tools. It’s powered by a library of pre-written expert prompts, each designed to run audits and analyses using first-party Google Search Console data, enhanced by tools like SEMrush and Moz.
Rather than asking users to create prompts from scratch, DIYSEO streamlines the process:
- Select a prompt (e.g., Mobile Performance)
- Connect GSC for real-time data access
- Receive analysis instantly
- Follow up in Chat History for guidance and clarification
Here’s how to use these prompts to diagnose and fix mobile-first indexing issues.
✅ Prompt: Mobile Performance
Use this to uncover technical and performance issues affecting your mobile experience. It highlights:
- Pages with poor mobile LCP, FID, and CLS scores
- Mobile usability errors reported in GSC
- Device-specific speed or rendering issues
- Discrepancies in CTR or engagement on mobile vs. desktop
👉 Use this insight to prioritize which mobile pages need the most urgent attention.
✅ Prompt: Indexation Overview
A critical prompt for ensuring your mobile pages are being properly discovered and indexed.
It reveals:
- Pages that are missing from the index
- Mobile-only URLs excluded from crawling
- Differences between sitemap inclusion and actual indexing
- Signs that mobile speed or structure may be hindering visibility
Pair this with the Top Exclusion Reasons prompt to isolate exactly why some pages are not being indexed.
✅ Prompt: Crawled – Not Indexed
This shows which mobile URLs Googlebot is seeing—but not indexing.
Common reasons include:
- Thin or duplicate mobile content
- Slow mobile rendering
- Blocked resources (e.g., scripts or stylesheets)
- Inconsistencies between mobile and desktop layout
DIYSEO GPT helps you pinpoint which pages are affected and recommend specific actions to resolve indexing friction.
Adapting Content for Mobile-First Using SEO AI Writer
Once you’ve identified which pages are underperforming or misaligned for mobile-first indexing, you can use the SEO AI Writer to:
✍️ Rebuild or Expand Mobile Content
Prompt:
“Rewrite this landing page section to include the same headings and keywords found on the desktop version. Make it short, scannable, and mobile-optimized.”
This ensures your mobile content is just as comprehensive and keyword-rich as the desktop version—without overwhelming the mobile layout.
🔗 Restore Internal Links
Prompt:
“Generate a list of internal pages I should link to from this mobile article to match the desktop internal link structure.”
This helps recover internal link equity that might be missing from the mobile version.
📱 Add Mobile-Specific Enhancements
Use the SEO AI Writer to:
- Create CTA blocks that fit mobile screens
- Generate ALT text for lazy-loaded images
- Write FAQ schema-compatible collapsible answers
Technical Mobile-First Fixes Based on AI Insights
While DIYSEO GPT won’t generate code, it shows you exactly what’s broken and where to apply these fixes:
Common Fixes:
| Issue | Action |
|---|---|
| Missing mobile content | Ensure parity with desktop text and headers |
| Blocked mobile scripts | Allow JS, CSS, images in robots.txt |
| Slow mobile load times | Compress images, use lazy loading, defer JS |
