Speed
Improve image delivery
663 KiB13 images could be 663 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.
Render-blocking requests
600 ms1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 600 ms.
Google Tag Manager adds 387 ms
387 msGoogle Tag Manager costs a phone 387 ms of main-thread work and 510 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.
Reduce unused JavaScript
340 KiBAbout 340 KiB of JavaScript is downloaded but never used on this page.
5 third-party services on the page
5 third-party services load with your homepage (Google Tag Manager, cookiehub.eu and cookiehub.net and others), adding 566 KiB and 438 ms of main-thread time.
Reduce unused CSS
280 ms · 46 KiBAbout 46 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 280 ms faster on a phone.
Use efficient cache lifetimes
164 KiB13 files are served with short cache lifetimes, so returning visitors download them again (164 KiB).
5 long tasks on the main thread
5 long tasks block the main thread while loading, the longest for 135 ms. During a long task the page ignores taps.
Chained critical requests
Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Images and page weight
Page weight: 2.9 MB in 52 requests
2.9 MBYour homepage downloads 2.9 MB in 52 requests on a phone: images 2.0 MB (32), scripts 750 KiB (6) and fonts 87 KiB (3). Under 2 MB keeps phones on slow connections fast.
3 images far larger than shown
329 KiB3 images are downloaded at several times the size a phone draws them, for example 254-Each-Second.webp at 1,920 px wide, shown at 390 px. Resized copies would save about 329 KiB.
About 0.8 g of CO₂ per visit
0.84 gBy the Sustainable Web Design model, a visit to your homepage emits about 0.84 g of CO₂e: 100.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.
