zirrus.com website review

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

Your mobile performance score is 64 (desktop: 99). Pages that score under 90 lose visitors before the first paint.

About 39 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 450 ms faster on a phone.

A phone's processor spends 3.4 s on main-thread work while loading, 880 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

11 long tasks block the main thread while loading, the longest for 334 ms. During a long task the page ignores taps.

5 third-party services load with your homepage (feedbucket.app, Google CDN and geniusmonkey.com and others), adding 195 KiB and 293 ms of main-thread time.

About 194 KiB of JavaScript is downloaded but never used on this page.

4 files are served with short cache lifetimes, so returning visitors download them again (160 KiB).

Polyfills for old browsers add 16 KiB JavaScript that modern phones do not need.

Desktop scores 99 but mobile only 64. A gap that wide usually means heavy scripts and images that hit phones hardest.

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.

3 KiB JavaScript is shipped twice across bundles.

3 KiB could be saved by minifying JavaScript.

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.

Scripts block taps and scrolling for 855 ms in total while the page loads. Good is under 200 ms.

Real visitors wait 231 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

The first text or image appears after 2.9 s on a phone. Good is under 1.8 s.

The page becomes fully interactive after 6.4 s. Good is under 3.8 s.

Your largest element takes 3.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Check Your Address for Available Internet Speeds & Pricing”. Most of its time is element render delay (1.5 s).

Visually, the page fills in at 3.8 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 183 ms to 195 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

By the Sustainable Web Design model, a visit to your homepage emits about 0.21 g of CO₂e: 24.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 button has no accessible name, so screen readers announce just “button”.

Some list items are not inside a list.

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

All page content should be contained by landmarks: 42 elements on the page fail this check, rated moderate by axe-core.

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

Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

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

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

Your meta description is 241 characters; Google truncates after about 160, so the end of your pitch is cut.

The homepage links to 71 pages on zirrus.com and 19 external pages.

https://zirrus.com/pages/contact, https://zirrus.com/a/docs/docs-category/technical-support-articles, https://zirrus.com/pages/bermuda-run and https://zirrus.com/pages/mocksville have no meta description, so Google writes the search snippet from whatever text it finds.

https://zirrus.com/pages/fiber-internet, https://zirrus.com/pages/mobile-plans, https://zirrus.com/pages/phones-and-devices, https://zirrus.com/pages/streaming-tv, https://zirrus.com/a/docs/docs-category/technical-support-articles and https://zirrus.com/pages/bermuda-run and 4 others have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 31 found) and read each the way a search engine does.

2 errors were logged to the browser console while the page loaded, for example “Access to XMLHttpRequest at 'https://app.five9.com/five9_clients/consoles_latest/SocialWidget/five9-social-widget.css?_…”.

The homepage shows no opening hours. If customers visit or call, show when.

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 471 words of visible text.

Before a visitor clicks anything, the page loads 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 5 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 7 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
