serfinitymedical.com website review

About 1.7 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 4.1 s faster on a phone.

12 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.1 s.

Your mobile performance score is 49. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 4.1 s on main-thread work while loading, 2.1 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (POWr, chatra.io and powrcdn.com and others), adding 2.9 MB and 1.6 s of main-thread time.

30 files are served with short cache lifetimes, so returning visitors download them again (781 KiB).

About 272 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 600 ms faster on a phone.

POWr costs a phone 467 ms of main-thread work and 295 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.

chatra.io costs a phone 424 ms of main-thread work and 623 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.

powrcdn.com costs a phone 239 ms of main-thread work and 1.1 MB 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.

Shopify costs a phone 88 ms of main-thread work and 535 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.

3 images could be 44 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 250 ms faster on a phone.

10 long tasks block the main thread while loading, the longest for 117 ms. During a long task the page ignores taps.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

Polyfills for old browsers add 37 KiB JavaScript that modern phones do not need.

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

2 KiB could be saved by minifying CSS.

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.

Your largest element takes 14.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

The page becomes fully interactive after 25.5 s. Good is under 3.8 s.

Visually, the page fills in at 9.1 s (Speed Index). Good is under 3.4 s.

The layout shifts by 0.251 while loading, so content jumps under the reader's thumb. Good is under 0.1.

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

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

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

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

Your homepage downloads 5.0 MB in 331 requests on a phone: scripts 3.0 MB (118), other files 913 KiB (156) and stylesheets 588 KiB (29). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.41 g of CO₂e: 169.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

14 elements use ARIA attributes their role does not allow, which confuses screen readers.

Images must have alternative text: 1 element on the page fails this check, rated critical by axe-core.

18 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.

16 elements have a tabindex above 0, which scrambles the keyboard order.

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

All page content should be contained by landmarks: 7 elements on the page fail this check, rated moderate by axe-core.

7 visible links have no text or label, so screen readers cannot say where they go.

1 form field has no label, so screen readers announce an empty box and autofill guesses.

No meta description, so Google writes its own snippet from whatever text it finds.

Your title is only 17 characters: “Serfinity Medical”. Between 30 and 65 characters leaves room to say what you do and for whom.

Structured data found (BreadcrumbList and WebSite) but with 1 problem, for example “BreadcrumbList: itemListElement is an empty list”.

No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 138 pages on serfinitymedical.com and 0 external pages.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

https://serfinitymedical.com/collections/drainage-and-suction, https://serfinitymedical.com/collections/gloves, https://serfinitymedical.com/collections/implants, https://serfinitymedical.com/collections/instruments, https://serfinitymedical.com/collections/diagnostic-instruments-and-supplies and https://serfinitymedical.com/collections/wound-closure and 9 others have no meta description, so Google writes the search snippet from whatever text it finds.

https://serfinitymedical.com/collections/drainage-and-suction, https://serfinitymedical.com/collections/gloves, https://serfinitymedical.com/collections/implants, https://serfinitymedical.com/collections/instruments, https://serfinitymedical.com/collections/diagnostic-instruments-and-supplies and https://serfinitymedical.com/collections/wound-closure and 9 others have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 53 found) and read each the way a search engine does.

1 image failed to load on a phone, for example https://bat.bing.com/action/0?ti=17413598&Ver=2&mid=5e6ed0db-9377-4a16-a1d2-28eeb41ada8e&bo=1&sid=a2d5f9d0db6911f19211a1b4837ecca0&vid=a2d5e750db6911f18a0af15753b057de&vids=1&msclkid=N&pi=918639831&lg.

16 of 43 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

3 third-party cookies are set on load; browsers are restricting these, so whatever relies on them breaks.

The page uses 2 deprecated browser APIs that will stop working in future browsers (“webkitRequestAnimationFrame is vendor-specific. Please use the standard requestAnimationFrame inste…”).

6 errors were logged to the browser console while the page loaded, for example “Uncaught (in promise) Price Rules is not enabled for this store.”.

1 image is displayed at the wrong aspect ratio, so it looks stretched or squashed.

Chrome logged issues while loading the page (“Cookie”).

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

Social proof on the homepage: 16 testimonial or review blocks. Pairing it with named testimonials or customer logos makes it far more convincing.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

The homepage carries about 338 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and Meta Pixel and 1 more (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 15 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 43 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
