growinglabs.com website review

11 images could be 1.0 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 5.3 s faster on a phone.

Your mobile performance score is 66. Pages that score under 90 lose visitors before the first paint.

About 309 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 600 ms faster on a phone.

10 files block the first paint until they finish downloading. Deferring or inlining them could save about 850 ms.

tidio.co costs a phone 81 ms of main-thread work and 515 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.

7 third-party services load with your homepage (Hotjar, tidio.co and Klaviyo and others), adding 807 KiB and 257 ms of main-thread time.

Polyfills for old browsers add 32 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 96 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).

About 15 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 30 ms faster on a phone.

5 files are served with short cache lifetimes, so returning visitors download them again (18 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.

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 12.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Single & Dual Jacketed 316L Grade Stainless Steel Reactors …”.

The page becomes fully interactive after 14.8 s. Good is under 3.8 s.

Visually, the page fills in at 6.7 s (Speed Index). Good is under 3.4 s.

Real visitors wait 2.6 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors wait 1.0 s for your server to start answering (75th percentile). Good is under 800 ms.

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

The first text or image appears after 2.3 s on a phone. Good is under 1.8 s.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 78 ms to 89 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 2.2 s to 2.6 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

hero-reactor.png weighs 613 KiB. On a phone connection a single image that size takes seconds.

3 images are downloaded at several times the size a phone draws them, for example hero-reactor.png at 4,472 px wide, shown at 384 px. Resized copies would save about 933 KiB.

Your homepage downloads 2.9 MB in 169 requests on a phone: images 1.1 MB (31), scripts 863 KiB (62) and other files 650 KiB (62). Under 2 MB keeps phones on slow connections fast.

2 images further down the page (288 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

1 image (138 KiB) is 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.

By the Sustainable Web Design model, a visit to your homepage emits about 0.83 g of CO₂e: 99.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

ARIA input fields must have an accessible name: 1 element on the page fails this check, rated serious by axe-core.

<html> element must have a lang attribute: 1 element on the page fails this check, rated serious by axe-core.

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

2 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.

The <html> element has no lang attribute, so screen readers may read the page in the wrong voice and accent.

Alternative text of images should not be repeated as text: 6 elements on the page fail this check, rated minor by axe-core.

Your title is 70 characters, so Google will cut it off around 60: “Growing Labs | Laboratory Equipment + Supplies for Research + Analysis”.

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

Open Graph is missing og:title and og:description, so shared links fall back to guesses.

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 56 pages on growinglabs.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.

We fetched 15 pages linked from your homepage (of 37 found) and read each the way a search engine does.

4 errors were logged to the browser console while the page loaded, for example “Unexpected end of input”.

2 images are displayed at the wrong aspect ratio, so they look stretched or squashed.

Large scripts ship without source maps.

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.

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

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 315 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Hotjar and Klaviyo and 1 more (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 14 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 18 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
