coro.net website review

19 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.8 s.

About 1.3 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.4 s faster on a phone.

26 files are served with short cache lifetimes, so returning visitors download them again (695 KiB).

Google Tag Manager costs a phone 1.6 s of main-thread work and 819 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.

Unpkg costs a phone 1.4 s of main-thread work and 96 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.

A phone's processor spends 14.4 s on main-thread work while loading, 8.4 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

hsappstatic.net costs a phone 1.2 s of main-thread work and 715 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 21. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

8 third-party services load with your homepage (Google Tag Manager, Unpkg and hsappstatic.net and others), adding 3.0 MB and 5.9 s of main-thread time.

About 156 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 750 ms faster on a phone.

Google CDN costs a phone 603 ms of main-thread work and 736 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.

20 long tasks block the main thread while loading, the longest for 649 ms. During a long task the page ignores taps.

Hubspot costs a phone 447 ms of main-thread work and 306 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.

The page has 2,302 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

9 KiB could be saved by minifying CSS.

Polyfills for old browsers add 32 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.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

2 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.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 169 ms to 249 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors see the first content after 2.9 s (75th percentile). Good is under 1.8 s.

The layout shifts by 0.193 while loading, so content jumps under the reader's thumb. Good is under 0.1.

1 image 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' largest content (lcp) went from 3.0 s to 3.5 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 4.5 MB in 159 requests on a phone: scripts 3.2 MB (62), other files 843 KiB (50) and stylesheets 248 KiB (20). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.29 g of CO₂e: 154.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Elements must only use permitted ARIA attributes: 7 elements on the page fail this check, rated serious by axe-core.

1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

All page content should be contained by landmarks: 51 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.

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

There are 3 <h1> headlines (“Workspace security built for Lean IT teams”, “Cybersecurity Made Easy” and “SE LabsCalls Coro "Outstanding"”). One clear main headline is easier for people and search engines.

Structured data found (FAQPage, Organization, SoftwareApplication and WPFooter) but with 1 problem, for example “SoftwareApplication: no offers (price) block”.

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

The homepage links to 170 pages on coro.net and 28 external pages.

https://www.coro.net/partners/coro-compass, https://www.coro.net/partners/tsds-agents and https://www.coro.net/partners/software-vendors all use the title “Partner With A Modern Cybersecurity Company | Coro”. Search engines can't tell which page to show for a search, so each competes with the others.

https://www.coro.net/platform, https://www.coro.net/platform/modules, https://www.coro.net/integrations, https://www.coro.net/platform/deployment, https://www.coro.net/platform/managed-services and https://www.coro.net/platform/pricing and 4 others have no meta description, so Google writes the search snippet from whatever text it finds.

https://www.coro.net/partners/coro-compass, https://www.coro.net/partners/tsds-agents and https://www.coro.net/partners/software-vendors use the same meta description. A description written for each page earns more clicks.

Your homepage links to 3 pages by a URL that isn't their canonical one, for example https://www.coro.net/integrations, whose canonical is https://www.coro.net/platform/integrations. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

https://www.coro.net/platform, https://www.coro.net/integrations, https://www.coro.net/partners/tsds-agents and https://www.coro.net/partners/software-vendors took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 58 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=211010448&tm=gtm002&Ver=2&mid=308e6499-70ed-4b26-84ed-9a1e5161c662&bo=1&sid=d3b75680d87211f1a94301bc127e9b36&vid=d3b780b0d87211f190dfbbfd907e2f00&vids=1&msclkid=N&pi=9.

4 of 10 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 third-party cookie is set on load; browsers are restricting these, so whatever relies on them breaks.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_EMPTY_RESPONSE”.

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.

Social proof on the homepage: 23 testimonial or review blocks. Pairing it with named testimonials or customer logos makes it far more convincing.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

There is no form on the homepage, so every lead has to click through to another page first.

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 1,174 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, HubSpot and LinkedIn Insight and 4 mores (measured from a US location before any click). A consent tool (Termly) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 32 cookies (measured from a US location before any click).

Loading the homepage contacts 52 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
