MobileRank – Mobile Performance Diagnostics

Google ranks mobile-first. Is your WordPress site ready?

MobileRank scans your pages using Google’s PageSpeed Insights API and tells you exactly what’s broken on mobile, why it’s hurting your Google rankings, and gives you the code to fix it.

Your caching plugin makes your site fast. MobileRank makes your mobile site fast and usable.

What MobileRank Does

• Scans your pages at mobile viewport using Google PageSpeed Insights
• Flags every issue with plain-English explanations (not developer jargon)
• Maps each issue to its SEO impact so you know what to fix first
• Provides copy-paste fixes — CSS, HTML, and PHP snippets you can use immediately
• Tracks Core Web Vitals — LCP, CLS, and INP scores per page
• Color-coded severity — see at a glance what’s critical vs. minor

Issues MobileRank Detects

• Layout shift (CLS) causing content to jump on mobile
• Oversized images served at desktop resolution on phones
• Missing lazy loading on off-screen images
• Tap targets too small or too close together
• Text too small to read without zooming
• Render-blocking CSS and JavaScript
• Missing or misconfigured viewport meta tag
• Unused CSS and JavaScript wasting bandwidth
• Slow Largest Contentful Paint (LCP)
• Missing text compression (gzip/brotli)
• And more…

Who Is MobileRank For?

• Site owners who see bad mobile PageSpeed scores but don’t know why
• Bloggers dependent on Google organic traffic
• WooCommerce store owners losing mobile conversions
• Freelancers & agencies who need to diagnose and fix client sites
