jasprmedical.com website review

A phone's processor spends 6.4 s on main-thread work while loading, 3.0 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (rebuyengine.com, heatmap.com and Google Tag Manager and others), adding 2.7 MB and 1.2 s of main-thread time.

Your mobile performance score is 78. Pages that score under 90 lose visitors before the first paint.

About 645 KiB of JavaScript is downloaded but never used on this page.

47 files are served with short cache lifetimes, so returning visitors download them again (417 KiB).

rebuyengine.com costs a phone 274 ms of main-thread work and 870 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.

9 files block the first paint until they finish downloading. Deferring or inlining them could save about 300 ms.

Google Tag Manager costs a phone 240 ms of main-thread work and 366 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.

Klaviyo costs a phone 102 ms of main-thread work and 318 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.

videowise.com costs a phone 56 ms of main-thread work and 669 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.

7 images could be 234 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

9 long tasks block the main thread while loading, the longest for 183 ms. During a long task the page ignores taps.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 150 ms).

Polyfills for old browsers add 81 KiB JavaScript that modern phones do not need.

About 59 KiB of CSS is downloaded but never applied on this page.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

Visually, the page fills in at 30.2 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 26.8 s. Good is under 3.8 s.

Real visitors wait 2.6 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors see the first content after 1.9 s (75th percentile). Good is under 1.8 s.

The first text or image appears after 2.8 s on a phone. Good is under 1.8 s.

Your largest element takes 2.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Professional Grade Air Cleaning. Built For Your Home.”. Most of its time is element render delay (2.4 s).

Scripts block taps and scrolling for 222 ms in total while the page loads. Good is under 200 ms.

1 image have no width and height attributes, so the layout jumps as each one loads.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 137 ms to 146 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 2.2 s to 2.3 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 5.9 MB in 555 requests on a phone: scripts 2.2 MB (140), other files 1.6 MB (312) and fonts 853 KiB (14). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.67 g of CO₂e: 200.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

ARIA attributes must conform to valid values: 4 elements on the page fail this check, rated critical by axe-core.

5 tap targets are too small or too close together to hit reliably with a finger.

All page content should be contained by landmarks: 6 elements on the page fail this check, rated moderate by axe-core.

1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

Your title is 66 characters, so Google will cut it off around 60: “Jaspr Air Scrubber - The First Air Scrubber Designed For Your Home”.

There are 2 <h1> headlines (“” and “Wildfire smoke doesn't stay outside.”). One clear main headline is easier for people and search engines.

Your meta description is 187 characters; Google truncates after about 160, so the end of your pitch is cut.

The homepage links to 31 pages on jasprmedical.com and 5 external pages.

https://jaspr.co/a/loop_subscriptions/get-subscription-link is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

https://jaspr.co/pages/faqs, https://jaspr.co/pages/reviews, https://jaspr.co/pages/about-us, https://jaspr.co/a/loop_subscriptions/get-subscription-link, https://jaspr.co/pages/contact-us and https://jaspr.co/policies/shipping-policy and 3 others have no meta description, so Google writes the search snippet from whatever text it finds.

https://jaspr.co/pages/reviews, https://jaspr.co/a/loop_subscriptions/get-subscription-link and https://jaspr.co/pages/partners have no <h1> headline, so visitors and search engines get no clear main topic.

https://jaspr.co/pages/reviews has under 150 words in the HTML. Thin pages rarely rank; if the text loads with JavaScript, crawlers that don't run it see even less.

We fetched 12 pages linked from your homepage and read each the way a search engine does.

3 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

The homepage carries about 811 words of visible text.

The page uses urgency cues (a countdown or limited-time wording).

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and Meta Pixel and 2 mores (measured from a US location before any click). No consent tool was detected. Visitors from the EU, UK and several US states must be asked first.

Opening the homepage sets 35 cookies, 1 of them by other companies (measured from a US location before any click).

No known cookie consent tool loads with the page. Some sites build their own banner, and some only show one to visitors from the EU.

Loading the homepage contacts 59 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
