fourthfrontier.com website review

11 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.7 s.

7 third-party services load with your homepage (flash-speed.com, Calendly and Amplitude Mobile Analytics and others), adding 5.4 MB and 20 ms of main-thread time.

Shopify costs a phone 0 ms of main-thread work and 5.3 MB 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.

23 images could be 386 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

The page has 1,784 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

2 long tasks block the main thread while loading, the longest for 52 ms. During a long task the page ignores taps.

About 31 KiB of CSS is downloaded but never applied on this page.

8 files are served with short cache lifetimes, so returning visitors download them again (22 KiB).

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 wait 2.7 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors see the first content after 2.6 s (75th percentile). Good is under 1.8 s.

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

Visually, the page fills in at 4.5 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 2.3 s on a phone. Good is under 1.8 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 137 ms to 138 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 6.6 MB in 88 requests on a phone: media 5.0 MB (2), images 996 KiB (51) and scripts 323 KiB (22). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.87 g of CO₂e: 224.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Delayed refresh under 20 hours must not be used: 1 element on the page fails this check, rated critical by axe-core.

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

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

1 frame has no title, so screen-reader users cannot tell what it contains.

Headings should not be empty: 1 element on the page fails this check, rated minor by axe-core.

There are 2 <h1> headlines (“Fourth Frontier Technologies LLC” and “Advancing Heart Health through Continuous Monitor…”). One clear main headline is easier for people and search engines.

Your meta description is 182 characters; Google truncates after about 160, so the end of your pitch is cut.

The homepage links to 129 pages on fourthfrontier.com and 34 external pages.

/products/frontier-heart-program has no <title>, so Google invents the link text in results.

/products/frontier-heart-program has no meta description, so Google writes the search snippet from whatever text it finds.

/products/frontier-x3, /pages/for-cyclist, /pages/for-runners, /pages/for-individuals, /pages/for-healthcare and /pages/why-frontier-x2 and 9 others have no <h1> headline, so visitors and search engines get no clear main topic.

/products/frontier-x3, /pages/for-cyclist, /pages/for-runners, /pages/for-individuals, /pages/for-healthcare and /pages/why-frontier-x2 and 7 others have under 150 words in the HTML. Thin pages rarely rank; if the text loads with JavaScript, crawlers that don't run it see even less.

We fetched 15 pages linked from your homepage (of 56 found) and read each the way a search engine does.

3 errors were logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 429 ()”.

1 link to other sites is dead, for example http://bhf.org.uk/-/media/files/for-professionals/research/heart-statistics/bhf-cvd-statistics-global-factsheet.pdf (404).

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.

fourthfrontier.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.

fourthfrontier.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.

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 phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

The homepage has only about 10 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.

The page uses urgency cues (a countdown or limited-time wording).

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

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.

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