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 can be tested, because the run sends a plain anonymous request with no cookies or credentials. Staging sites behind basic auth or an IP allowlist will return an access error instead of a result.

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.

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.

By Deepak Shukla — Founder & CEO, Pearl Lemon

Paste your URLs — one per line, up to 25

0 URLs ready

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 This 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 Issues

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

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.

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.
