gentmax.com website review

14 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.2 s.

8 third-party services load with your homepage (Google Tag Manager, Intercom and Clarity and others), adding 1.3 MB and 901 ms of main-thread time.

Your mobile performance score is 69. Pages that score under 90 lose visitors before the first paint.

About 403 KiB of JavaScript is downloaded but never used on this page.

A phone's processor spends 3.8 s on main-thread work while loading, 1.9 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Google Tag Manager costs a phone 278 ms of main-thread work and 438 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.

The page has 2,581 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Klaviyo costs a phone 128 ms of main-thread work and 307 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.

7 long tasks block the main thread while loading, the longest for 217 ms. During a long task the page ignores taps.

14 files are served with short cache lifetimes, so returning visitors download them again (75 KiB).

2 images could be 29 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Polyfills for old browsers add 18 KiB JavaScript that modern phones do not need.

About 10 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.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

Visually, the page fills in at 11.3 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 16.8 s. Good is under 3.8 s.

Your largest element takes 4.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

Scripts block taps and scrolling for 357 ms in total while the page loads. Good is under 200 ms.

Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

Your homepage downloads 3.0 MB in 274 requests on a phone: scripts 1.3 MB (93), other files 1.1 MB (130) and stylesheets 290 KiB (35). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.85 g of CO₂e: 101.6 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.

Your meta description is 170 characters; Google truncates after about 160, so the end of your pitch is cut.

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

No favicon is declared in the HTML, so browser tabs and Google's mobile results may show a generic icon.

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

The homepage links to 35 pages on gentmax.com and 0 external pages.

Your Organization JSON-LD is missing logo, 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.

/customer_authentication/redirect has no <title>, so Google invents the link text in results.

/customer_authentication/redirect is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

/collections/all, /customer_authentication/redirect, /policies/shipping-policy, /blogs/all, /policies/refund-policy and /policies/privacy-policy and 1 other have no meta description, so Google writes the search snippet from whatever text it finds.

/customer_authentication/redirect has no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 14 pages linked from your homepage and read each the way a search engine does.

1 image failed to load on a phone, for example https://bat.bing.com/action/0?ti=187033480&Ver=2&mid=189951dc-353b-437a-84ae-13eb4dd9c869&bo=1&sid=5f3abee0d74f11f195337d8de2d74296&vid=5f3acc00d74f11f1a0954b5827d0d8b3&vids=1&msclkid=N&pi=918639831&l.

1 third-party cookie is set on load; browsers are restricting these, so whatever relies on them breaks.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 404 ()”.

Chrome logged issues while loading the page (“Cookie”).

1 link from your homepage to your own site is broken, for example https://www.gentmax.com/cdn-cgi/l/email-protection (404).

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

1 link go through two or more redirects, for example https://www.gentmax.com/customer_authentication/redirect?locale=en&region_country=US.

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.

gentmax.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.

gentmax.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 1,487 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, Klaviyo and Meta Pixel and 4 mores (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 18 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 34 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
