spediesel.com website review

Your mobile performance score is 14. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 9.6 s on main-thread work while loading, 4.4 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 6,823 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

8 third-party services load with your homepage (POWr, loox.io and powrcdn.com and others), adding 3.0 MB and 2.0 s of main-thread time.

35 files are served with short cache lifetimes, so returning visitors download them again (1.7 MB).

About 1.0 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 150 ms faster on a phone.

7 images could be 179 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 600 ms faster on a phone.

POWr costs a phone 538 ms of main-thread work and 1.0 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.

10 files block the first paint until they finish downloading. Deferring or inlining them could save about 550 ms.

20 long tasks block the main thread while loading, the longest for 507 ms. During a long task the page ignores taps.

About 205 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

loox.io costs a phone 352 ms of main-thread work and 28 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.

powrcdn.com costs a phone 248 ms of main-thread work and 608 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.

Shopify costs a phone 149 ms of main-thread work and 552 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.

Klaviyo costs a phone 148 ms of main-thread work and 342 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.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 250 ms).

Polyfills for old browsers add 27 KiB JavaScript that modern phones do not need.

7 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.

4 KiB could be saved by minifying CSS.

Visually, the page fills in at 17.6 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 32.0 s. Good is under 3.8 s.

The layout shifts by 1.004 while loading, so content jumps under the reader's thumb. Good is under 0.1.

Your largest element takes 6.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

Scripts block taps and scrolling for 1.8 s in total while the page loads. Good is under 200 ms.

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

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

Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

Your homepage downloads 6.2 MB in 384 requests on a phone: scripts 2.3 MB (118), images 1.3 MB (27) and fonts 1.2 MB (18). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.75 g of CO₂e: 210.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

44 elements use ARIA attributes their role does not allow, which confuses screen readers.

1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

All page content should be contained by landmarks: 101 elements on the page fail this check, rated moderate by axe-core.

Heading levels should only increase by one: 1 element on the page fails this check, rated moderate by axe-core.

Document should not have more than one banner landmark: 1 element on the page fails this check, rated moderate by axe-core.

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

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.

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

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

There is no <h1>, so neither visitors nor Google get a clear main headline.

44 links have no real href, so search engines can't follow them.

Your title is 67 characters, so Google will cut it off around 60: “SPE Motorsport: Performance Products for Enthusiasts by Enthusiasts”.

Your canonical URL points to spemotorsport.com, not spediesel.com, so Google may credit that host instead.

Your meta description is 180 characters; Google truncates after about 160, so the end of your pitch is cut.

Structured data found (Organization and WebSite) but with 1 problem, for example “Organization: url points at a different host (https://www.spemotorsport.com)”.

The homepage links to 379 pages on spediesel.com and 3 external pages.

There is no https://spediesel.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 130 found) and read each the way a search engine does.

3 third-party cookies are set on load; browsers are restricting these, so whatever relies on them breaks.

The page uses 2 deprecated browser APIs that will stop working in future browsers (“webkitRequestAnimationFrame is vendor-specific. Please use the standard requestAnimationFrame inste…”).

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

Chrome logged issues while loading the page (“Cookie”).

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

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.

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 492 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo 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 15 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 44 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
