Regression on brilliantbakery.co.uk — alert sent before client noticed
Everything your agency needs to monitor client performance
Ongoing visibility across your entire portfolio — not one-off checks you forget to run.
Regression Alerts
When a client's score drops 10+ points after a plugin or theme update, you get an email. Not the client — you, first.
White-label PDF Reports
Branded reports with your logo and colours — generate a PDF for any site in one click and attach it straight to your retainer invoice.
Pitch Deck Comparisons
Run a side-by-side speed comparison for any prospect versus their competitors. Share the link or download a PDF for new-business presentations.
Try a comparison →Platform-specific Fix Plans
Prioritised recommendations tailored to WordPress, Shopify, WooCommerce, Magento, and more — not generic advice your dev team has to decipher.
Shareable Client Reports

The business case your clients need to hear
When a client asks why performance work matters, these are the numbers. Use them in your proposals, retainer reviews, and pitch decks.
90+
the Google ranking threshold
Faster sites rank higher
Google uses Core Web Vitals as a direct ranking signal. Pages that score above 90 consistently outrank slower competitors in organic search.
+7%
conversion lift per second saved
Faster sites convert better
A 1-second improvement in load time increases conversions by up to 7%. For an e-commerce site doing £500k a year, that is £35,000 in extra revenue.
53%
of users leave after 3 seconds
Faster sites keep visitors
53% of mobile users abandon a page that takes longer than 3 seconds to load. Speed is the single biggest driver of first-impression trust.
Win new clients with data, not promises
Run a side-by-side PageSpeed comparison between a prospect and their competitors. Share the link in your pitch or export it as a PDF — it shows exactly where they're losing ground and why they need you.
