Enable Brotli with a gzip fallback for HTML, CSS, and JavaScript so text assets shrink on the wire without double-compressing images or burning origin CPU that quietly hurts TTFB and PageSpeed scores.
Safari 26.2 exposes Largest Contentful Paint and Event Timing so you can measure LCP and INP for Safari users. Here is how to collect those metrics, and which Chrome-only reports still leave iOS out.
When LCP is red, start with TTFB, then clear the path to the LCP element, mark it fetchpriority="high", and defer non-critical JavaScript until after load. Four practical changes teams can ship this week.
Web fonts carry your brand, but full character sets often waste kilobytes on every page view. Font subsetting keeps only the glyphs you need so LCP and First Contentful Paint improve without dropping custom typography.
Largest Contentful Paint often comes down to one big image. Here is how to pick formats, size for the viewport, wire responsive images, and verify the win—without guessing.
Mobile and desktop Core Web Vitals can tell different stories. Here’s how to monitor both so your reports stay accurate and your fixes stay prioritised.
You've run PageSpeed Insights. The scores are poor. You've optimised images, minified CSS, and still LCP stays red. Or CLS keeps spiking on client sites. Or users complain that clicks feel sluggish even though the page "loads fast". The problem isn't always obvious—some of the worst PageSpeed mistakes look like best practice at first glance.
The Three Numbers That Control Your Search Rankings Google's Core Web Vitals boil down to three metrics: LCP, INP, and CLS. Each measures a different dimension of user experience, and each has specifi...
WordPress 6.8 ships speculative loading (prefetch by default). Plugins that prerender more eagerly can improve next-page feel, but they can also burn bandwidth and muddy first-visit Core Web Vitals. Here is how agencies choose settings without guessing.
Time to First Byte includes more than server work. Name Unattributed Navigation Overhead (UNO) in client reports so the residual after redirect, DNS, connection, and request timing is not silently blamed on origin PHP.
