Bulk Mobile-Friendly Test

Check mobile-friendliness across up to 25 URLs at once. Viewport, tap targets, text size, content fit — pass/fail per URL.

Google indexes the mobile version of your site first — so anything that breaks on mobile breaks your SEO. Bulk mobile checks let you sweep an entire site catalogue in one go to catch the pages that quietly slipped.

## What this tool does

Paste up to 25 URLs. We render each one at a 412×823 mobile viewport (the same dimensions Google uses) and run the same checklist as the single-URL Mobile-Friendly Test: viewport meta tag, tap-target sizes, text legibility, content fit. Each row gets a pass/fail and a one-line summary.

## Why use it

Mobile readiness is one of those things that regresses silently. A new page template ships, a designer hard-codes a 1200px container, a third-party widget renders a 12px font — and suddenly three pages that used to pass now fail. Bulk audits catch that drift weekly.

What this tool checks

• Viewport meta tag presence and configuration
• Tap target size (Google minimum 48×48 CSS pixels)
• Text size legibility (≥16px body text)
• Content fits the viewport without horizontal scroll
• Per-URL pass / fail verdict

Why it matters

Google uses mobile-first indexing — every URL is judged by its mobile experience. One failed page across a portfolio is one less ranking opportunity.

How to fix what it finds

• Filter the CSV for "Not mobile-friendly" — those are your urgent fixes
• Add a viewport meta tag if missing: <meta name="viewport" content="width=device-width, initial-scale=1">
• Audit your design system for buttons under 44×44 — that is the most common bulk failure
• For sites with horizontal scroll on mobile, audit fixed-width containers and overflowing tables

Methodology

Each URL is loaded in a headless browser at 412×823 (Pixel-class mobile viewport) with mobile user-agent emulation. We measure: presence of <meta name="viewport">, smallest computed tap-target size for interactive elements, the smallest computed font-size on visible text, and whether the document is wider than the viewport (triggering horizontal scroll). The pass/fail verdict is the same composite used by Google's mobile-friendly criteria and our single-URL tool. We do not run a full Lighthouse pass in bulk mode — for the deep score, click into the single-URL tool.

Frequently asked questions

How is this different from PageSpeed Insights mobile?

PSI runs a full Lighthouse pass per URL (slow). This tool runs just the mobile-friendly subset (fast) so you can sweep 25 URLs in seconds.

Why did a page pass here but fail in Search Console?

Search Console retests on a delay. If you fixed a tap-target issue recently, it can take days to update.

Can I test password-protected pages?

No — only publicly reachable URLs.

Does this account for Core Web Vitals?

No — CWV is its own dimension. Use the Core Web Vitals Checker (single-URL) for that.

What viewport size do you emulate?

412×823 with a mobile user-agent — same as Google's mobile-friendly tester.

Why does my page show horizontal scroll only sometimes?

Usually a third-party embed (chat widget, ad slot) that loads at variable widths. Audit those embeds first.
