themicrolabs.com website review

About 758 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.2 s faster on a phone.

Your mobile performance score is 49. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 5.4 s on main-thread work while loading, 2.7 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google Tag Manager, Shopify and Clarity and others), adding 2.1 MB and 1.4 s of main-thread time.

Google Tag Manager costs a phone 425 ms of main-thread work and 347 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.

11 long tasks block the main thread while loading, the longest for 390 ms. During a long task the page ignores taps.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 350 ms.

Shopify costs a phone 264 ms of main-thread work and 703 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.

13 files are served with short cache lifetimes, so returning visitors download them again (319 KiB).

Klaviyo costs a phone 199 ms of main-thread work and 310 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.

azurefd.net costs a phone 35 ms of main-thread work and 322 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.

About 60 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 240 ms faster on a phone.

Polyfills for old browsers add 50 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

5 images could be 125 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

8 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.

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.

Real visitors see the first content after 3.8 s (75th percentile). Good is under 1.8 s.

Your largest element takes 15.0 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

Visually, the page fills in at 13.3 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 19.6 s. Good is under 3.8 s.

Real visitors wait 3.9 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 103 ms to 121 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 3.3 s to 3.9 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Scripts block taps and scrolling for 548 ms in total while the page loads. Good is under 200 ms.

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

Your homepage downloads 4.3 MB in 411 requests on a phone: scripts 2.0 MB (100), other files 1.5 MB (278) and images 617 KiB (18). Under 2 MB keeps phones on slow connections fast.

Energize_Your_Day.webp is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

4 images further down the page (84 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 1.21 g of CO₂e: 145.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

7 tap targets are too small or too close together to hit reliably with a finger.

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

Scrollable region must have keyboard access: 2 elements on the page fail this check, rated serious by axe-core.

All page content should be contained by landmarks: 2 elements on the page fail this check, rated moderate by axe-core.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

The viewport tag blocks pinch-zoom, which low-vision visitors rely on.

Headings skip levels (h2 → h5, h2 → h5 and h2 → h5), which makes the page harder to scan with a screen reader.

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

The homepage links to 31 pages on themicrolabs.com and 1 external page.

https://themicrolabs.com/products/microlabs%E2%84%A2 and https://themicrolabs.com/products/microlabs-vitamin-d3-k2 all use the title “Vitamin D3 K2 Softgels 10,000 IU MK7 | D3 K2 Supplement”. Search engines can't tell which page to show for a search, so each competes with the others.

https://themicrolabs.com/tools/recurring/get-subscription-access, https://themicrolabs.com/policies/shipping-policy, https://themicrolabs.com/policies/refund-policy, https://themicrolabs.com/policies/privacy-policy and https://themicrolabs.com/policies/terms-of-service have no meta description, so Google writes the search snippet from whatever text it finds.

https://themicrolabs.com/products/microlabs%E2%84%A2 and https://themicrolabs.com/products/microlabs-vitamin-d3-k2 use the same meta description. A description written for each page earns more clicks.

Your homepage links to 1 page by a URL that isn't its canonical one, for example https://themicrolabs.com/products/microlabs%E2%84%A2, whose canonical is https://themicrolabs.com/products/microlabs-vitamin-d3-k2. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

https://themicrolabs.com/apps/parcelpanel has no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 13 pages linked from your homepage and read each the way a search engine does.

12 of 20 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

The page uses 1 deprecated browser API that will stop working in future browsers (“Unload event listeners are deprecated and will be removed.”).

1 error was logged to the browser console while the page loaded, for example “TypeError: Cannot create proxy with a non-object as target or handler”.

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.

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

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 305 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and Meta Pixel 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 22 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 31 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
