pcb-hero.com website review

Your mobile performance score is 48 (desktop: 86). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 4.2 s on main-thread work while loading, 2.1 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (chatra.io, wisepops.net and Google Tag Manager and others), adding 754 KiB and 1.3 s of main-thread time.

17 images could be 327 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 550 ms faster on a phone.

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

About 659 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 150 ms faster on a phone.

chatra.io costs a phone 697 ms of main-thread work and 333 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.

10 long tasks block the main thread while loading, the longest for 333 ms. During a long task the page ignores taps.

6 files are served with short cache lifetimes, so returning visitors download them again (42 KiB).

About 81 KiB of CSS is downloaded but never applied on this page.

Desktop scores 86 but mobile only 48. A gap that wide usually means heavy scripts and images that hit phones hardest.

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

Visually, the page fills in at 9.8 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 13.5 s. Good is under 3.8 s.

The first text or image appears after 3.4 s on a phone. Good is under 1.8 s.

Real visitors wait 996 ms for your server to start answering (75th percentile). Good is under 800 ms.

Scripts block taps and scrolling for 462 ms in total while the page loads. Good is under 200 ms.

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

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 161 ms to 170 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 2.0 s to 2.1 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.9 MB in 326 requests on a phone: other files 1.1 MB (243), images 873 KiB (26) and scripts 844 KiB (45). Under 2 MB keeps phones on slow connections fast.

2 images are downloaded at several times the size a phone draws them, for example [email protected] at 648 px wide, shown at 162 px. Resized copies would save about 24 KiB.

9 images further down the page (294 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 0.83 g of CO₂e: 99.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Interactive controls must not be nested: 4 elements on the page fail this check, rated serious by axe-core.

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

Your title is 81 characters, so Google will cut it off around 60: “Turnkey PCB/PCBA Manufacturing Expert, Partner of Startups & Campaigns – PCB HERO”.

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

Your meta description is 313 characters; Google truncates after about 160, so the end of your pitch is cut.

Your <h1> is empty.

The homepage links to 145 pages on pcb-hero.com and 1 external page.

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.

https://www.pcb-hero.com/collections/pcb-fabrication, https://www.pcb-hero.com/collections/pcb-assembly, https://www.pcb-hero.com/collections/pcb-reverse-engineering, https://www.pcb-hero.com/collections/servo-motor-rotating-accessories, https://www.pcb-hero.com/collections/car-accessories and https://www.pcb-hero.com/collections/wifi-module and 2 others have no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 15 pages linked from your homepage (of 74 found) and read each the way a search engine does.

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

Chrome logged issues while loading the page (“Content security policy”).

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.

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.

The homepage has only about 234 words of visible text; thin pages give Google and first-time buyers little to go on.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager and Meta Pixel (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 13 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 21 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
