Multi-URL audit. 5 URLs side-by-side.
Enter up to 5 URLs (one per line). We run Google PSI sequentially against each and produce a comparison table of Performance, SEO, Accessibility, Best Practices scores plus the worst-performing audit per URL.
Enter up to 5 URLs (one per line). We run Google PSI sequentially against each (typical 2-3 minutes for 5 URLs) and return a comparison table of Performance / SEO / Accessibility / Best Practices scores with the worst audit per URL flagged.

Side-by-side surfaces patterns.
Single-URL audits answer 'how is this page doing?'. Multi-URL audits answer 'how do these pages compare?' — which template is fastest, which competitor is winning the speed race, which version of the new PDP scores better in A/B testing. The tool above runs Google PSI sequentially across up to 5 URLs (10-15 minutes total) and returns a comparison table with worst-audit-per-URL flagged. Common patterns surfaced: PDP templates 20-40 points worse than homepage on Performance (image-heavy), competitor wins on JS budget, new template version scores better than legacy.
Three high-impact uses for multi-URL audit. Section comparison (homepage vs PDP vs collection vs cart vs checkout) — surfaces template-specific patterns. A/B test validation (old version vs new version) — confirms the new build is at least as fast as the old. Competitive benchmarking (your top 4 competitors' equivalents of the URL you care about) — a useful sales-call data point and a focused performance target.
Tools in the same cluster: Lighthouse Score Checker for the single-URL deep dive. Site Health Checker for the composite 4-cat grade. Website Audit for the broader scorecard with PDF export.
Five answers.
When should I use multi-URL audit?
Three common scenarios. One, comparing site sections (homepage vs PDP vs collection page) — performance often varies dramatically by template. Two, A/B testing template variants — old PDP vs new PDP scores compared side-by-side. Three, competitive benchmarking — your URL alongside 4 competitor URLs to spot relative strengths/weaknesses. The 5-URL limit is a PSI-quota self-protection (free PSI tier resets every 24h).
Why sequential, not parallel?
Google's free PSI quota is shared across all requests from your IP. Running 5 URLs in parallel would consume the same quota faster and risk hitting throttling mid-batch. Sequential runs (one URL at a time, ~30s each) take 2.5 minutes total but stay well within the per-IP throttle window. The tool surfaces per-URL progress so you see which URL is currently running.
What does the worst-audit-per-URL flag mean?
For each URL, the tool identifies the single highest-impact failed Lighthouse audit and surfaces it. This is usually the most actionable insight — knowing which one fix would lift each URL most. Common worst-audit results: 'render-blocking resources' (CSS/JS in head), 'unused JavaScript' (tree-shaking opportunity), 'properly size images', 'cumulative-layout-shift' (font swap or late-loading images). Use the per-URL worst audit as the prioritized fix target.
Can I export the results?
Yes — click the Copy results button after the audit completes. The clipboard receives a plain-text comparison table (URL × category scores + worst audit) formatted for paste into Slack, Google Docs, Notion, or email. The full per-URL PSI report is linked out for each row so you can drill in via pagespeed.web.dev.
Does this tool save my data?
The URLs are sent only to Google's public PageSpeed Insights API, one at a time. Nothing is logged on Digital Heroes servers.
Templates scoring uneven?
Our SEO + web development engagements run a per-template performance audit, prioritize the worst-scoring sections, and ship a 30-day fix sprint that brings every template above the 80 threshold.
