covalentlithium.com website review

About 585 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.5 s faster on a phone.

7 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.8 s.

8 third-party services load with your homepage (Squarespace, Google Tag Manager and JSDelivr CDN and others), adding 1.6 MB and 845 ms of main-thread time.

Your mobile performance score is 62. Pages that score under 90 lose visitors before the first paint.

Squarespace costs a phone 617 ms of main-thread work and 1.1 MB 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 136 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.

5 files are served with short cache lifetimes, so returning visitors download them again (77 KiB).

7 long tasks block the main thread while loading, the longest for 238 ms. During a long task the page ignores taps.

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

Polyfills for old browsers add 33 KiB JavaScript that modern phones do not need.

2 images could be 21 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

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 10.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Covalent Lithium”.

The page becomes fully interactive after 10.7 s. Good is under 3.8 s.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 1.3 s to 1.8 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors see the first content after 1.9 s (75th percentile). Good is under 1.8 s.

The first text or image appears after 2.6 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 4.7 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 300 ms in total while the page loads. Good is under 200 ms.

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

By the Sustainable Web Design model, a visit to your homepage emits about 0.49 g of CO₂e: 58.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

There are 3 <h1> headlines (“Our project”, “Our business” and “News”). One clear main headline is easier for people and search engines.

Structured data found (LocalBusiness, Organization and WebSite) but with 2 problems, for example “WebSite: image is not an absolute URL ("//images.squarespace-cdn.com/content/v1/5d8c061dd46259208da…”.

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

The homepage links to 50 pages on covalentlithium.com and 4 external pages.

Your Organization JSON-LD is missing name, url, logo and description. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

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.

Your homepage links to /about, which answers with an error. Visitors hit a dead end and search engines drop it.

/about/our-business, /about/our-values, /about/our-leadership-team, /about/health-and-safety, /about/corporate-governance and /our-project and 6 others have no meta description, so Google writes the search snippet from whatever text it finds.

/about/our-business, /about/our-values, /about/our-leadership-team and /community have no <h1> headline, so visitors and search engines get no clear main topic.

/about/our-business, /about/our-values, /about/our-leadership-team and /community have under 150 words in the HTML. Thin pages rarely rank; if the text loads with JavaScript, crawlers that don't run it see even less.

We fetched 15 pages linked from your homepage and read each the way a search engine does.

2 of 9 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 “Access to XMLHttpRequest at 'https://static1.squarespace.com/static/versioned-site-css/5d8c061dd46259208da3638c/316/5c5…”.

1 link from your homepage to your own site is broken, for example https://www.covalentlithium.com/about/ (404).

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.

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.

covalentlithium.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.

covalentlithium.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.

The homepage has only about 112 words of visible text; thin pages give Google and first-time buyers little to go on.

Your phone number appears as text but isn't a tel: link, so phone visitors can't tap to call.

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

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.

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 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 6 cookies, 1 of them by other companies (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 16 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
