athlon.com website review

30 files are served with short cache lifetimes, so returning visitors download them again (341 KiB).

Your mobile performance score is 82. Pages that score under 90 lose visitors before the first paint.

About 133 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 300 ms faster on a phone.

Google Tag Manager costs a phone 211 ms of main-thread work and 298 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.

3 third-party services load with your homepage (Google Tag Manager, Clarity and Google Analytics), adding 326 KiB and 256 ms of main-thread time.

3 long tasks block the main thread while loading, the longest for 152 ms. During a long task the page ignores taps.

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.

Your largest element takes 4.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Your mobility challenge is our professional challenge”.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 130 ms to 158 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

The page becomes fully interactive after 6.7 s. Good is under 3.8 s.

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

By the Sustainable Web Design model, a visit to your homepage emits about 0.28 g of CO₂e: 33.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

All page content should be contained by landmarks: 2 elements on the page fail this check, rated moderate by axe-core.

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

Alternative text of images should not be repeated as text: 1 element on the page fails this check, rated minor by axe-core.

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

Elements with visible text labels do not have matching accessible names. (1 element).

5 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

The homepage links to 115 pages on athlon.com and 20 external pages.

Your robots.txt shuts out Perplexity (PerplexityBot). These fetch pages to answer people's questions and cite the source, so your site can't be quoted or linked in those answers.

There is no /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.

robots.txt blocks ClaudeBot and CCBot, which collect pages to train models. That's a legitimate choice and doesn't by itself stop the site appearing in AI answers.

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

2 links to other sites are dead, for example https://support.google.com/policies/contact/general_privacy_form (404).

No Strict-Transport-Security header, so browsers may still try plain http first on a return visit.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

athlon.com's DNS answers are not signed. DNSSEC stops attackers forging them to send visitors or email elsewhere; most registrars switch it on in a click, though most sites still run without it.

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

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.

A local customer looking to call finds no phone number on the homepage. Add one, ideally as a tap-to-call link.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

The homepage shows no opening hours. If customers visit or call, show when.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

The homepage carries about 621 words of visible text.

Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

Before a visitor clicks anything, the page loads Google Analytics, Google Tag Manager and Microsoft Clarity (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 2 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 5 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
