channelmaster.com website review

About 227 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.8 s faster on a phone.

Your mobile performance score is 51. Pages that score under 90 lose visitors before the first paint.

9 images could be 191 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 750 ms faster on a phone.

A phone's processor spends 2.2 s on main-thread work while loading, 1.1 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

7 third-party services load with your homepage (Google/Doubleclick Ads, Google Tag Manager and Shopify and others), adding 504 KiB and 352 ms of main-thread time.

11 files block the first paint until they finish downloading. Deferring or inlining them could save about 250 ms.

6 long tasks block the main thread while loading, the longest for 119 ms. During a long task the page ignores taps.

5 files are served with short cache lifetimes, so returning visitors download them again (22 KiB).

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.

Your largest element takes 10.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “House with TV antenna at sunset”.

The first text or image appears after 4.2 s on a phone. Good is under 1.8 s.

The page becomes fully interactive after 10.4 s. Good is under 3.8 s.

Visually, the page fills in at 6.4 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 112 ms to 152 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

The layout shifts by 0.197 while loading, so content jumps under the reader's thumb. Good is under 0.1.

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

Your homepage downloads 2.1 MB in 187 requests on a phone: other files 681 KiB (73), images 628 KiB (30) and scripts 608 KiB (51). Under 2 MB keeps phones on slow connections fast.

South-Mountain-TV-Towers-Alt.jpg is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

1 image is downloaded at several times the size a phone draws it, for example South-Mountain-TV-Towers-Alt.jpg at 1,900 px wide, shown at 390 px. Resized copies would save about 77 KiB.

2 images further down the page (65 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 0.59 g of CO₂e: 70.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

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

All page content should be contained by landmarks: 22 elements on the page fail this check, rated moderate by axe-core.

60 form fields have no label, so screen readers announce an empty box and autofill guesses.

Alternative text of images should not be repeated as text: 3 elements on the page fail this check, rated minor by axe-core.

There are 3 <h1> headlines (“”, “The Leader In Broadcast Television” and “The Leader in Broadcast Television”). One clear main headline is easier for people and search engines.

Your meta description is 309 characters; Google truncates after about 160, so the end of your pitch is cut.

2 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

The homepage links to 93 pages on channelmaster.com and 10 external pages.

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.

/collections/all has no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 15 pages linked from your homepage (of 46 found) and read each the way a search engine does.

3 of 15 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

HSTS is set, but max-age is 91 days; one year is the recommended minimum.

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.

X-XSS-Protection is set to “1; mode=block”; the header is deprecated and can introduce bugs. Use 0 or remove it.

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

channelmaster.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 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 708 words of visible text.

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 Ads, Google Analytics, Google Tag Manager and Meta Pixel (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 10 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.
