activeradiator.com website review

26 files are served with short cache lifetimes, so returning visitors download them again (1.2 MB).

9 files block the first paint until they finish downloading. Deferring or inlining them could save about 3.0 s.

2 images could be 471 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 2.1 s faster on a phone.

About 210 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.1 s faster on a phone.

Your mobile performance score is 61 (desktop: 80). Pages that score under 90 lose visitors before the first paint.

About 74 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 450 ms faster on a phone.

Google Tag Manager costs a phone 370 ms of main-thread work and 502 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 third-party services load with your homepage (Google Tag Manager, mailerlite.com and Google Analytics and others), adding 522 KiB and 375 ms of main-thread time.

5 long tasks block the main thread while loading, the longest for 163 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.

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.

For real visitors the layout shifts by 0.35 (75th percentile). Good is under 0.1.

Your largest element takes 11.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “We’re Moving to a Larger Facility! Our Joliet location is m…”.

The first text or image appears after 4.4 s on a phone. Good is under 1.8 s.

The page becomes fully interactive after 11.4 s. Good is under 3.8 s.

Real visitors wait 1.0 s for your server to start answering (75th percentile). Good is under 800 ms.

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

joliet-to-tinley-park-1536x1024-t.png weighs 489 KiB. On a phone connection a single image that size takes seconds.

1 image is downloaded at several times the size a phone draws it, for example joliet-to-tinley-park-1536x1024-t.png at 1,536 px wide, shown at 306 px. Resized copies would save about 314 KiB.

1 image (489 KiB) is JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

By the Sustainable Web Design model, a visit to your homepage emits about 0.49 g of CO₂e: 58.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 2 elements on the page fail this check, rated moderate by axe-core.

Main landmark should not be contained in another landmark: 1 element on the page fails this check, rated moderate by axe-core.

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

Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

Headings skip levels (h2 → h4, h2 → h4 and h2 → h4), which makes the page harder to scan with a screen reader.

Your title is 84 characters, so Google will cut it off around 60: “Heavy-Duty Cooling Products - Radiators, Cores, Condensers, & More | Active Radiator”.

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

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

The homepage links to 57 pages on activeradiator.com and 1 external page.

We fetched 15 pages linked from your homepage (of 37 found) and read each the way a search engine does.

3 errors were logged to the browser console while the page loaded, for example “messages is not defined”.

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.

X-Content-Type-Options: nosniff is missing, so browsers may guess file types.

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.

activeradiator.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.

activeradiator.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.

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

The homepage has only about 228 words of visible text; thin pages give Google and first-time buyers little to go on.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

We found no DKIM key on the selectors the big email providers use. If you send through one of them, turning on DKIM signing improves delivery.

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