thomasmiller.com website review

About 436 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.8 s faster on a phone.

Your mobile performance score is 66 (desktop: 98). Pages that score under 90 lose visitors before the first paint.

Google Tag Manager costs a phone 161 ms of main-thread work and 310 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 CDN costs a phone 60 ms of main-thread work and 348 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.

4 images could be 90 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 250 ms faster on a phone.

5 third-party services load with your homepage (Google Tag Manager, Google CDN and Google Analytics and others), adding 724 KiB and 239 ms of main-thread time.

3 files are served with short cache lifetimes, so returning visitors download them again (20 KiB).

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 150 ms.

Polyfills for old browsers add 10 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 100 ms faster on a phone.

3 long tasks block the main thread while loading, the longest for 93 ms. During a long task the page ignores taps.

About 22 KiB of CSS is downloaded but never applied on this page.

Desktop scores 98 but mobile only 66. 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.

Your largest element takes 7.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

The first text or image appears after 3.3 s on a phone. Good is under 1.8 s.

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 0.9 s to 1.4 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

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

Visually, the page fills in at 5.3 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 96 ms to 102 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

1 image further down the page (22 KiB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 0.30 g of CO₂e: 35.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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.

No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

No XML sitemap at http://www.thomasmiller.com/sitemap.xml, so Google discovers your pages only by following links.

The homepage links to 43 pages on thomasmiller.com and 24 external pages.

Your Organization JSON-LD is missing logo, sameAs (social profiles) and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

There is no https://www.thomasmiller.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 35 found) and read each the way a search engine does.

2 images are displayed at the wrong aspect ratio, so they look stretched or squashed.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

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 346 words of visible text.

Before a visitor clicks anything, the page loads Google Analytics and Google Tag Manager (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.

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.
