servicejan.com website review

Your mobile performance score is 64. Pages that score under 90 lose visitors before the first paint.

About 101 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 600 ms faster on a phone.

4 long tasks block the main thread while loading, the longest for 516 ms. During a long task the page ignores taps.

A phone's processor spends 4.0 s on main-thread work while loading, 1.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 150 ms.

2 third-party services load with your homepage (Google Tag Manager and Google Analytics), adding 178 KiB and 120 ms of main-thread time.

2 images could be 61 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Polyfills for old browsers add 14 KiB JavaScript that modern phones do not need.

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

Your largest element takes 5.7 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “ServiceJan”.

Visually, the page fills in at 5.2 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 427 ms in total while the page loads. Good is under 200 ms.

The page becomes fully interactive after 5.7 s. Good is under 3.8 s.

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.

2 images are downloaded at several times the size a phone draws them, for example servicejan-lockup.1qcajuz4n29qq.png at 782 px wide, shown at 112 px. Resized copies would save about 170 KiB.

2 images (239 KiB) are 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 0.25 g of CO₂e: 30.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

ARIA attributes must conform to valid values: 1 element on the page fails this check, rated critical by axe-core.

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

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

The homepage links to 39 pages on servicejan.com and 13 external pages.

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.

We fetched 15 pages linked from your homepage (of 18 found) and read each the way a search engine does.

3 of 5 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

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.

servicejan.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.

servicejan.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.

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: 5 trust badges. 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.

There is no form on the homepage, so every lead has to click through to another page first.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

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 424 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 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.

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