1-act.com website review

23 files block the first paint until they finish downloading. Deferring or inlining them could save about 7.7 s.

About 828 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 4.7 s faster on a phone.

Your mobile performance score is 39 (desktop: 55). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

8 third-party services load with your homepage (Google Tag Manager, Google CDN and Hubspot and others), adding 2.0 MB and 1.6 s of main-thread time.

16 files are served with short cache lifetimes, so returning visitors download them again (222 KiB).

Google Tag Manager costs a phone 611 ms of main-thread work and 857 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 549 ms of main-thread work and 733 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.

A phone's processor spends 4.0 s on main-thread work while loading, 2.4 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

9 images could be 322 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

20 long tasks block the main thread while loading, the longest for 174 ms. During a long task the page ignores taps.

About 46 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 120 ms faster on a phone.

7 KiB could be saved by minifying JavaScript.

Polyfills for old browsers add 7 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 100 ms faster on a phone.

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.

The first text or image appears after 13.4 s on a phone. Good is under 1.8 s.

Your largest element takes 21.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “RELIABLE THERMAL MANAGEMENT SOLUTIONS”.

The page becomes fully interactive after 24.7 s. Good is under 3.8 s.

Visually, the page fills in at 13.4 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 627 ms in total while the page loads. Good is under 200 ms.

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

Real visitors wait 1.3 s for your server to start answering (75th percentile). Good is under 800 ms.

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

Over the last 25 four-week periods to 2026-10-10, real Chrome visitors' tap response (inp) went from 92 ms to 96 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-10, real Chrome visitors' largest content (lcp) went from 2.3 s to 2.5 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 9.1 MB in 146 requests on a phone: media 4.6 MB (1), scripts 2.0 MB (51) and fonts 1.2 MB (8). Under 2 MB keeps phones on slow connections fast.

1 image further down the page (70 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 2.57 g of CO₂e: 308.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 element use ARIA attributes their role does not allow, which confuses screen readers.

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

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

All page content should be contained by landmarks: 11 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.

1 visible link has no text or label, so screen readers cannot say where it goes.

Your meta description is 162 characters; Google truncates after about 160, so the end of your pitch is cut.

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

The homepage links to 227 pages on 1-act.com and 7 external pages.

Your Organization JSON-LD is missing sameAs (social profiles), description 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 /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.

/thermal-solutions/passive/pcm, /thermal-solutions/active and /thermal-solutions/active/liquid-cooling have no meta description, so Google writes the search snippet from whatever text it finds.

/contact-act, /thermal-solutions/passive/heat-pipes/hik-plates, /thermal-solutions/passive/heat-pipes/pulsating, /thermal-solutions/passive/heat-pipes/vapor-chambers, /thermal-solutions/passive/heat-pipes/high-temp and /thermal-solutions/passive/loop-thermosyphons and 2 others have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 100 found) and read each the way a search engine does.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

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

No Content-Security-Policy header, the main browser-side defence against injected scripts.

Neither X-Frame-Options nor a CSP frame-ancestors policy is set, so any site can embed yours in a frame.

No Referrer-Policy header, so full URLs can leak to the sites you link to.

No Permissions-Policy header to switch off camera, microphone and location for embedded content.

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

1-act.com has no CAA record, so any certificate authority may issue a certificate for it. A CAA record naming your provider (for example letsencrypt.org) closes that door.

1-act.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.

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.

Social proof on the homepage: 26 testimonial or review blocks. Pairing it with named testimonials or customer logos makes it far more convincing.

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

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 2,024 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 Ads, Google Analytics, Google Tag Manager, Hotjar and HubSpot and 1 more (measured from a US location before any click). A consent tool (CookieYes) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 13 cookies (measured from a US location before any click).

Loading the homepage contacts 27 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
