wow-how.com website review

About 663 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 5.4 s faster on a phone.

11 images could be 889 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 3.0 s faster on a phone.

14 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.9 s.

Your mobile performance score is 43 (desktop: 87). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

8 third-party services load with your homepage (Google CDN, Google Tag Manager and exactdn.com and others), adding 2.7 MB and 1.2 s of main-thread time.

About 84 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 740 ms faster on a phone.

Google CDN costs a phone 544 ms of main-thread work and 731 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 3.8 s on main-thread work while loading, 1.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

exactdn.com costs a phone 170 ms of main-thread work and 1.4 MB 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 232 ms of main-thread work and 362 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.

The page has 2,194 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

10 long tasks block the main thread while loading, the longest for 219 ms. During a long task the page ignores taps.

Polyfills for old browsers add 26 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

Desktop scores 87 but mobile only 43. 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.

2 files are served with short cache lifetimes, so returning visitors download them again (3 KiB).

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.

The first text or image appears after 9.1 s on a phone. Good is under 1.8 s.

Your largest element takes 19.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Medik8 C-Tetra Advanced | 3D promo”.

The page becomes fully interactive after 19.8 s. Good is under 3.8 s.

Visually, the page fills in at 9.1 s (Speed Index). Good is under 3.4 s.

Real visitors wait 2.8 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors see the first content after 2.1 s (75th percentile). Good is under 1.8 s.

Real visitors wait 1.5 s for your server to start answering (75th percentile). Good is under 800 ms.

Scripts block taps and scrolling for 546 ms in total while the page loads. Good is under 200 ms.

12 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' largest content (lcp) went from 2.2 s to 2.8 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 3.4 MB in 111 requests on a phone: scripts 1.6 MB (36), images 1.1 MB (44) and other files 361 KiB (8). Under 2 MB keeps phones on slow connections fast.

5 images further down the page (484 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

8 images are downloaded at several times the size a phone draws them, for example Nexoom_Video_Audio1_8.png at 1,024 px wide, shown at 330 px. Resized copies would save about 64 KiB.

1 image (152 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 0.97 g of CO₂e: 116.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

2 buttons have no accessible name, so screen readers announce just “button”.

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

64 images have no alt text, which hurts accessibility and image search.

All page content should be contained by landmarks: 72 elements on the page fail this check, rated moderate by axe-core.

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

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

Headings should not be empty: 1 element on the page fails this check, rated minor by axe-core.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

The homepage links to 67 pages on wow-how.com and 133 external pages.

There is no https://wow-how.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.

https://wow-how.com/animated-series-films and https://wow-how.com/motion-graphics took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 41 found) and read each the way a search engine does.

6 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

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 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 613 words of visible text.

Before a visitor clicks anything, the page loads Google Ads and Google Tag Manager (measured from a US location before any click). A consent tool (CookieYes) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 4 cookies (measured from a US location before any click).

Loading the homepage contacts 15 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
