satechi.net website review

About 987 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.2 s faster on a phone.

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

Signyfyd costs a phone 1.1 s of main-thread work and 260 KiB of downloads while your page loads. That alone is enough to make taps feel slow. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

Your mobile performance score is 41. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 6.7 s on main-thread work while loading, 4.0 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 4,328 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

8 third-party services load with your homepage (Signyfyd, Osano CMP and Klaviyo and others), adding 1.9 MB and 2.4 s of main-thread time.

13 images could be 869 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

20 long tasks block the main thread while loading, the longest for 686 ms. During a long task the page ignores taps.

19 files are served with short cache lifetimes, so returning visitors download them again (214 KiB).

Klaviyo costs a phone 323 ms of main-thread work and 508 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.

Osano CMP costs a phone 324 ms of main-thread work and 82 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.

ZenDesk costs a phone 217 ms of main-thread work and 431 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.

rebuyengine.com costs a phone 141 ms of main-thread work and 300 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.

About 86 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

Polyfills for old browsers add 60 KiB JavaScript that modern phones do not need.

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

9 KiB could be saved by minifying JavaScript.

6 KiB could be saved by minifying CSS.

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.

Your largest element takes 14.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Satechi ExtendView USB4 Dual HDMI Multiport Adapter powerin…”.

The page becomes fully interactive after 30.0 s. Good is under 3.8 s.

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

Scripts block taps and scrolling for 773 ms in total while the page loads. Good is under 200 ms.

The first text or image appears after 3.2 s on a phone. Good is under 1.8 s.

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

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

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 145 ms to 155 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 2.3 s to 2.3 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 6.6 MB in 359 requests on a phone: images 2.9 MB (73), scripts 2.5 MB (125) and other files 796 KiB (124). Under 2 MB keeps phones on slow connections fast.

Mobile_DUO_GIF_1.gif weighs 1.0 MB. On a phone connection a single image that size takes seconds.

23 images (2.9 MB) are JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

By the Sustainable Web Design model, a visit to your homepage emits about 1.87 g of CO₂e: 224.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

2 buttons have no accessible name, so screen readers announce just “button”.

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

36 images have no alt text, which hurts accessibility and image search.

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

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

ARIA role should be appropriate for the element: 5 elements on the page fail this check, rated minor by axe-core.

Headings skip levels (h1 → h5, h1 → h5 and h1 → h4), which makes the page harder to scan with a screen reader.

There are 6 <h1> headlines (“USB4 Speed.Dual 4K Clarity.”, “USB4 Speed.Dual 4K Clarity.” and “New Duo.New Setup.”). One clear main headline is easier for people and search engines.

Structured data found (Organization and WebSite) but with 1 problem, for example “Organization: logo is not an absolute URL ("Liquid error (snippets/json-ld-organization line 12): i…”.

No twitter:card tag. X falls back to Open Graph, which is set, so this is minor.

The homepage links to 266 pages on satechi.net and 2 external pages.

We fetched 15 pages linked from your homepage (of 88 found) and read each the way a search engine does.

12 of 48 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

3 errors were logged to the browser console while the page loaded, for example “Refused to apply style from 'https://satechi.com/cdn/shop/t/393/assets/component-quick-add.min.css?v=92001' because its…”.

Large scripts ship without source maps.

Social proof on the homepage: 10 trust badges. Pairing it with named testimonials or customer logos makes it far more convincing.

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.

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 798 words of visible text.

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

Before a visitor clicks anything, the page loads Klaviyo (measured from a US location before any click). A consent tool (Osano) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 11 cookies (measured from a US location before any click).

Loading the homepage contacts 25 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
