6gcool.com website review

19 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.6 s.

Your mobile performance score is 89. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Facebook, Google Tag Manager and POWr and others), adding 640 KiB and 560 ms of main-thread time.

About 241 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 350 ms faster on a phone.

A phone's processor spends 2.4 s on main-thread work while loading, 811 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 files are served with short cache lifetimes, so returning visitors download them again (249 KiB).

6 long tasks block the main thread while loading, the longest for 146 ms. During a long task the page ignores taps.

Polyfills for old browsers add 13 KiB JavaScript that modern phones do not need.

About 13 KiB of CSS is downloaded but never applied on this page.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

The page becomes fully interactive after 8.3 s. Good is under 3.8 s.

Visually, the page fills in at 5.1 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 2.2 s on a phone. Good is under 1.8 s.

Scripts block taps and scrolling for 210 ms in total while the page loads. Good is under 200 ms.

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

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 109 ms to 108 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Ilmanpuhdistimet_mobiili_170x.webp is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

By the Sustainable Web Design model, a visit to your homepage emits about 0.50 g of CO₂e: 60.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

All page content should be contained by landmarks: 3 elements on the page fail 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 (h1 → h4 and h2 → h5), which makes the page harder to scan with a screen reader.

Your title is only 28 characters: “Purely Better Air | Lifa Air”. Between 30 and 65 characters leaves room to say what you do and for whom.

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

Your <h1> is empty.

The homepage links to 76 pages on 6gcool.com and 7 external pages.

We fetched 15 pages linked from your homepage (of 35 found) and read each the way a search engine does.

12 of 17 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 error was logged to the browser console while the page loaded, for example “Shopify's Google Analytics stub called with: [array Array] See https://help.shopify.com/manual/promoting-marketing/pixe…”.

HSTS is set, but max-age is 91 days; one year is the recommended minimum.

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.

X-XSS-Protection is set to “1; mode=block”; the header is deprecated and can introduce bugs. Use 0 or remove it.

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

lifa-air.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.

lifa-air.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 phone number appears as text but isn't a tel: link, so phone visitors can't tap to call.

The homepage carries about 317 words of visible text.

DMARC is set to p=none, so mail pretending to be 6gcool.com is still delivered. Add a report address, check the reports, then move to quarantine.

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, Google Tag Manager and Meta Pixel (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 14 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 18 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
