tgs.com website review

56 files are served with short cache lifetimes, so returning visitors download them again (3.7 MB).

About 1.2 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 4.5 s faster on a phone.

Google CDN costs a phone 1.0 s of main-thread work and 1.8 MB of downloads while your page loads. That alone is enough to make taps feel slow. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

11 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.1 s.

Your mobile performance score is 42. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 6.8 s on main-thread work while loading, 3.8 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google CDN, Other Google APIs/SDKs and LinkedIn and others), adding 2.4 MB and 1.6 s of main-thread time.

20 long tasks block the main thread while loading, the longest for 232 ms. During a long task the page ignores taps.

About 80 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

7 images could be 168 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 50 ms faster on a phone.

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

6 KiB could be saved by minifying CSS.

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.

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.

Real visitors see the first content after 3.4 s (75th percentile). Good is under 1.8 s.

The first text or image appears after 11.7 s on a phone. Good is under 1.8 s.

Your largest element takes 15.0 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Energy Starts With Us”.

The page becomes fully interactive after 19.2 s. Good is under 3.8 s.

Visually, the page fills in at 11.7 s (Speed Index). Good is under 3.4 s.

Real visitors wait 3.9 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 96 ms to 117 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Scripts block taps and scrolling for 525 ms in total while the page loads. Good is under 200 ms.

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

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 3.1 s to 3.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 37.3 MB in 117 requests on a phone: media 32.8 MB (4), scripts 2.3 MB (35) and images 750 KiB (27). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 10.56 g of CO₂e: 1267.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Some lists contain elements other than list items, which screen readers announce wrongly.

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

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

3 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.

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

There are 2 <h1> headlines (“Delivering High-Quality Data and Insightsto Power…” and “Gemini X: Encoded for more. Engineered for better…”). One clear main headline is easier for people and search engines.

Your meta description is 234 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: sameAs is an empty list”.

1 link has no real href, so search engines can't follow it.

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

The homepage links to 90 pages on tgs.com and 10 external pages.

The HTML your server sends has 603 of the 1,016 words a browser shows. AI crawlers don't run JavaScript, so they miss the rest.

There is no https://www.tgs.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 43 found) and read each the way a search engine does.

4 of 16 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

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

2 images are served at too low a resolution for sharp phone screens.

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.

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 1,016 words of visible text.

Before a visitor clicks anything, the page loads HubSpot (measured from a US location before any click). A consent tool (HubSpot cookie banner) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 2 cookies (measured from a US location before any click).

Loading the homepage contacts 23 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
