PageSpeed Insights Tool Demo
Core Web Vitals reporting inside Google Sheets
The PageSpeed Insights Tool - CWV add-on turns a blank spreadsheet into a repeatable Core Web Vitals and website speed test workspace. Instead of checking URLs one by one, SEO and web teams can paste a list of pages, run mobile or desktop analysis, and compare LCP, CLS, INP, and performance scores in one sheet.
Use it for template audits, product page checks, localization QA, client reporting, bulk CWV testing, and post-release monitoring when you need clean page-level Google PageSpeed data without building a custom API script.
Built for SEO audits
Review groups of URLs before technical SEO reports, migrations, redesigns, or sprint handoffs with a repeatable website performance test.
Spreadsheet native
Keep inputs, results, notes, owners, and follow-up actions in the same Google Sheet.
Mobile and desktop
Create separate sheets for mobile and desktop so device-specific performance gaps stay visible.
Google data source
Pull metrics from Google PageSpeed Insights instead of relying on manual screenshots.
