greencocylinders.com website review

9 images could be 616 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 2.9 s faster on a phone.

15 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.6 s.

About 195 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 910 ms faster on a phone.

Your mobile performance score is 67. Pages that score under 90 lose visitors before the first paint.

25 files are served with short cache lifetimes, so returning visitors download them again (95 KiB).

Weebly costs a phone 167 ms of main-thread work and 529 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.

1 third-party service load with your homepage (Weebly), adding 529 KiB and 167 ms of main-thread time.

About 29 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

Polyfills for old browsers add 10 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

2 long tasks block the main thread while loading, the longest for 70 ms. During a long task the page ignores taps.

13 KiB could be saved by minifying JavaScript.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Your largest element takes 8.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

The page becomes fully interactive after 8.2 s. Good is under 3.8 s.

The first text or image appears after 3.0 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 5.1 s (Speed Index). Good is under 3.4 s.

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

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.

6 images (631 KiB) are JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

6 images further down the page (529 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

2 images are downloaded at several times the size a phone draws them, for example grennco-chart_orig.png at 1,100 px wide, shown at 360 px. Resized copies would save about 13 KiB.

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.

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

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: 3 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.

No meta description, so Google writes its own snippet from whatever text it finds.

Your title is only 14 characters: “GREENCO - Home”. Between 30 and 65 characters leaves room to say what you do and for whom.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.

No favicon is declared in the HTML, so browser tabs and Google's mobile results may show a generic icon.

No twitter:card tag. X falls back to Open Graph, which is set, so this is minor.

The homepage links to 12 pages on greencocylinders.com and 3 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.

/products.html and /contact-us.html have no meta description, so Google writes the search snippet from whatever text it finds.

/contact-us.html has no <h1> headline, so visitors and search engines get no clear main topic.

/contact-us.html has 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 2 pages linked from your homepage and read each the way a search engine does.

1 image is served at too low a resolution for sharp phone screens.

http://greencocylinders.com does not redirect to https, so some visitors land on the insecure version.

No Strict-Transport-Security header, so browsers may still try plain http first on a return visit.

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

Neither X-Frame-Options nor a CSP frame-ancestors policy is set, so any site can embed yours in a frame.

X-Content-Type-Options: nosniff is missing, so browsers may guess file types.

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.

greencocylinders.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.

greencocylinders.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.

Social proof on the homepage: 1 trust badge. Pairing it with named testimonials or customer logos makes it far more convincing.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

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 524 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.

Opening the homepage sets 3 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 4 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
