extremeturbosystems.com website review

The page has 4,179 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Your mobile performance score is 69. Pages that score under 90 lose visitors before the first paint.

15 files are served with short cache lifetimes, so returning visitors download them again (787 KiB).

13 images could be 630 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

6 files block the first paint until they finish downloading. Deferring or inlining them could save about 450 ms.

6 third-party services load with your homepage (PayPal, Shopify and logbase.io and others), adding 1.2 MB and 278 ms of main-thread time.

Shopify costs a phone 43 ms of main-thread work and 350 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.

cloudwaysapps.com costs a phone 0 ms of main-thread work and 577 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 108 KiB of JavaScript is downloaded but never used on this page.

2 long tasks block the main thread while loading, the longest for 76 ms. During a long task the page ignores taps.

Polyfills for old browsers add 28 KiB JavaScript that modern phones do not need.

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 layout shifts by 0.601 while loading, so content jumps under the reader's thumb. Good is under 0.1.

The page becomes fully interactive after 6.9 s. Good is under 3.8 s.

Your largest element takes 3.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

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

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 84 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 1.1 s to 1.0 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.5 MB in 223 requests on a phone: images 978 KiB (22), other files 776 KiB (96) and scripts 521 KiB (70). Under 2 MB keeps phones on slow connections fast.

ETS_Black_Friday_TurboKit_12pct_Banner.png 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).

By the Sustainable Web Design model, a visit to your homepage emits about 0.72 g of CO₂e: 86.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Images must have alternative text: 4 elements on the page fail this check, rated critical by axe-core.

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

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

Scrollable region must have keyboard access: 1 element on the page fails this check, rated serious by axe-core.

All page content should be contained by landmarks: 4 elements on the page fail this check, rated moderate by axe-core.

1 form field has no label, so screen readers announce an empty box and autofill guesses.

Headings skip levels (h3 → h5 and h2 → h5), which makes the page harder to scan with a screen reader.

Your title is only 21 characters: “Extreme Turbo Systems”. Between 30 and 65 characters leaves room to say what you do and for whom.

Your meta description is only 39 characters: “Your source for high performance parts!”. 70 to 160 characters is enough to sell the click.

1 link use generic text like “click here” or “learn more”, which tells Google nothing about the page behind it.

Your <h1> is empty.

The homepage links to 281 pages on extremeturbosystems.com and 9 external pages.

We fetched 15 pages linked from your homepage (of 131 found) and read each the way a search engine does.

2 images failed to load on a phone, for example https://www.extremeturbosystems.com/.

5 of 18 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

3 errors were logged to the browser console while the page loaded, for example “Cannot read properties of null (reading 'addEventListener')”.

1 image is displayed at the wrong aspect ratio, so it looks stretched or squashed.

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 analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

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

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 477 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 12 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.
