powersupplymall.com website review

Your mobile performance score is 86. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (FontAwesome CDN, Google Tag Manager and Google CDN and others), adding 751 KiB and 802 ms of main-thread time.

FontAwesome CDN costs a phone 507 ms of main-thread work and 204 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.

Google Tag Manager costs a phone 183 ms of main-thread work and 319 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.

A phone's processor spends 2.1 s on main-thread work while loading, 1.1 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 1,888 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

About 184 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.

7 files block the first paint until they finish downloading. Deferring or inlining them could save about 250 ms.

11 files are served with short cache lifetimes, so returning visitors download them again (86 KiB).

About 217 KiB of JavaScript is downloaded but never used on this page.

2 long tasks block the main thread while loading, the longest for 123 ms. During a long task the page ignores taps.

3 images could be 40 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

36 KiB JavaScript is shipped twice across bundles.

12 KiB could be saved by minifying CSS.

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.

The page becomes fully interactive after 7.1 s. Good is under 3.8 s.

Your largest element takes 3.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Authentic Mean Well, LTech, Amphenol and the brands enginee…”. Most of its time is element render delay (2.1 s).

Visually, the page fills in at 3.9 s (Speed Index). Good is under 3.4 s.

Your homepage downloads 2.1 MB in 211 requests on a phone: other files 978 KiB (117), scripts 654 KiB (54) and images 275 KiB (14). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.59 g of CO₂e: 70.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

Elements must only use permitted ARIA attributes: 4 elements on the page fail this check, rated serious by axe-core.

All page content should be contained by landmarks: 7 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.

10 visible links have no text or label, so screen readers cannot say where they go.

2 form fields have no label, so screen readers announce an empty box and autofill guesses.

Headings skip levels (h1 → h3 and h2 → h4), which makes the page harder to scan with a screen reader.

Elements with visible text labels do not have matching accessible names. (3 elements).

Your title is 73 characters, so Google will cut it off around 60: “Mean Well Power Supplies | 7,500+ Products In Stock | powersupplymall.com”.

Your meta description is 162 characters; Google truncates after about 160, so the end of your pitch is cut.

The homepage links to 175 pages on powersupplymall.com and 4 external pages.

Your robots.txt lets ChatGPT search (OAI-SearchBot), ChatGPT (ChatGPT-User) and Perplexity (PerplexityBot) read the homepage but closes other sections to them, so answers about those pages can't cite you.

There is no https://powersupplymall.com/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.

We fetched 15 pages linked from your homepage (of 90 found) and read each the way a search engine does.

14 of 36 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

2 errors were logged to the browser console while the page loaded, for example “Access to XMLHttpRequest at 'https://cdn.optinly.net/v1/styles.css' from origin 'https://powersupplymall.com' has been …”.

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.

Social proof on the homepage: 44 testimonial or review blocks. Pairing it with named testimonials or customer logos makes it far more convincing.

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 953 words of visible text.

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 17 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 23 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
