Speed
Reduce unused JavaScript
2.3 s · 382 KiBAbout 382 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.3 s faster on a phone.
Render-blocking requests
2.5 s14 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.5 s.
Reduce unused CSS
1.2 s · 221 KiBAbout 221 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 1.2 s faster on a phone.
Mobile performance score: 53
53/100Your mobile performance score is 53. Pages that score under 90 lose visitors before the first paint.
7 third-party services on the page
7 third-party services load with your homepage (Accessibe Accessibility Overlay, cookiepro.com and Google Tag Manager and others), adding 707 KiB and 546 ms of main-thread time.
Use efficient cache lifetimes
300 ms · 55 KiB6 files are served with short cache lifetimes, so returning visitors download them again (55 KiB).
6 long tasks on the main thread
6 long tasks block the main thread while loading, the longest for 258 ms. During a long task the page ignores taps.
Main-thread work: 2.3 s
A phone's processor spends 2.3 s on main-thread work while loading, 895 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.
Improve image delivery
150 ms · 18 KiB2 images could be 18 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 150 ms faster on a phone.
Font display
50 msWeb fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).
Legacy JavaScript
20 KiBPolyfills for old browsers add 20 KiB JavaScript that modern phones do not need.
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.
Forced reflow
Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.
Minify CSS
5 KiB5 KiB could be saved by minifying CSS.

AI search readiness
No llms.txt

Content and conversion
No call to action on the first screen
On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.
Thin social proof
Social proof on the homepage: 8 testimonial or review blocks. Pairing it with named testimonials or customer logos makes it far more convincing.
No direct contact details
No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.
Only about 209 words
The homepage has only about 209 words of visible text; thin pages give Google and first-time buyers little to go on.
No form on the homepage
There is no form on the homepage, so every lead has to click through to another page first.
No risk reducer
No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.
2 checks passed
