Speed
Reduce unused JavaScript
2.6 s · 639 KiBAbout 639 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.6 s faster on a phone.
8 third-party services on the page
8 third-party services load with your homepage (Shopify, Google Tag Manager and vitals.app and others), adding 1.9 MB and 960 ms of main-thread time.
Mobile performance score: 63
63/100Your mobile performance score is 63. Pages that score under 90 lose visitors before the first paint.
Render-blocking requests
800 ms4 files block the first paint until they finish downloading. Deferring or inlining them could save about 800 ms.
Shopify adds 365 ms
365 msShopify costs a phone 365 ms of main-thread work and 355 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.
Google Tag Manager adds 320 ms
320 msGoogle Tag Manager costs a phone 320 ms of main-thread work and 506 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.
Main-thread work: 2.9 s
A phone's processor spends 2.9 s on main-thread work while loading, 1.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.
vitals.app adds 103 ms
103 msvitals.app costs a phone 103 ms of main-thread work and 343 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.
tidio.co adds 66 ms
66 mstidio.co costs a phone 66 ms of main-thread work and 515 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 CSS
290 ms · 60 KiBAbout 60 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 290 ms faster on a phone.
Use efficient cache lifetimes
200 ms · 106 KiB10 files are served with short cache lifetimes, so returning visitors download them again (106 KiB).
Legacy JavaScript
150 ms · 47 KiBPolyfills for old browsers add 47 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.
Minify JavaScript
150 ms · 26 KiB26 KiB could be saved by minifying JavaScript.
6 long tasks on the main thread
6 long tasks block the main thread while loading, the longest for 147 ms. During a long task the page ignores taps.
Improve image delivery
54 KiB1 image could be 54 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.
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.

Other pages
2 pages share a title

5 pages without a meta description

3 pages share a meta description
https://www.pluxbiosignals.com/collections/myology, https://www.pluxbiosignals.com/collections/neurology and https://www.pluxbiosignals.com/collections/respiratory use the same meta description. A description written for each page earns more clicks.
