4k60hz.com website review

8 third-party services load with your homepage (Bigcommerce, Google Tag Manager and Google CDN and others), adding 1.3 MB and 735 ms of main-thread time.

About 523 KiB of JavaScript is downloaded but never used on this page.

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 400 ms.

23 files are served with short cache lifetimes, so returning visitors download them again (342 KiB).

Bigcommerce costs a phone 245 ms of main-thread work and 527 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 costs a phone 214 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.

Google CDN costs a phone 159 ms of main-thread work and 293 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.

5 long tasks block the main thread while loading, the longest for 161 ms. During a long task the page ignores taps.

7 images could be 81 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

About 50 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.

5 KiB could be saved by minifying JavaScript.

The page becomes fully interactive after 9.9 s. Good is under 3.8 s.

Scripts block taps and scrolling for 276 ms in total while the page loads. Good is under 200 ms.

Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

By the Sustainable Web Design model, a visit to your homepage emits about 0.38 g of CO₂e: 45.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Some list items are not inside a list.

Some lists contain elements other than list items, which screen readers announce wrongly.

1 tap target is too small or too close together to hit reliably with a finger.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

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.

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

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

Headings skip levels (h2 → h5), which makes the page harder to scan with a screen reader.

Your title is only 22 characters: “4K 60 Hz HDMI Products”. Between 30 and 65 characters leaves room to say what you do and for whom.

32 links have no real href, so search engines can't follow them.

Your meta description is only 64 characters: “4K 60 Hz 4:4:4 18-GBPS Products - Call 833 WOLFPACK 833 965 3722”. 70 to 160 characters is enough to sell the click.

Structured data found (untyped) but with 1 problem, for example “ld+json block 1 is not valid JSON (Unexpected end of JSON input)”.

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

No XML sitemap at https://www.4k60hz.com/sitemap.xml, so Google discovers your pages only by following links.

Your <h1> is empty.

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

The homepage links to 148 pages on 4k60hz.com and 13 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.

There is no /llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

/4k-60-hz-hdmi-over-lan-matrix-switchers.html has no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 15 pages linked from your homepage (of 48 found) and read each the way a search engine does.

11 of 41 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

2 errors were logged to the browser console while the page loaded, for example “$(...).accordion is not a function”.

5 images are served at too low a resolution for sharp phone screens.

No Content-Security-Policy header, the main browser-side defence against injected scripts.

HSTS is set, but max-age is 0 days; one year is the recommended minimum.

1 link go through two or more redirects, for example https://www.twitter.com/hdtvsupply/.

No Referrer-Policy header, so full URLs can leak to the sites you link to.

No Permissions-Policy header to switch off camera, microphone and location for embedded content.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

4k60hz.com is registered until Jan 2027. Make sure auto-renew is on and the card on file is current.

4k60hz.com has no CAA record, so any certificate authority may issue a certificate for it. A CAA record naming your provider (for example letsencrypt.org) closes that door.

4k60hz.com's DNS answers are not signed. DNSSEC stops attackers forging them to send visitors or email elsewhere; most registrars switch it on in a click, though most sites still run without it.

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

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust 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 321 words of visible text.

4k60hz.com has no DMARC record, so nothing tells receivers what to do with mail that fails SPF or DKIM. Gmail and Yahoo require DMARC from bulk senders.

4k60hz.com has no SPF record, so mail servers can't tell which servers may send email as you. Your mail lands in spam more often, and anyone can send mail pretending to be you.

We found no DKIM key on the selectors the big email providers use. If you send through one of them, turning on DKIM signing improves delivery.

4k60hz.com has no MX record, so it receives no email. SPF -all and DMARC reject still matter: they stop others sending mail as you.

Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

Before a visitor clicks anything, the page loads Google Analytics and Google Tag Manager (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 13 cookies (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 14 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
