partsof4.com website review

Your mobile performance score is 73. Pages that score under 90 lose visitors before the first paint.

17 files are served with short cache lifetimes, so returning visitors download them again (85 KiB).

About 119 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 450 ms faster on a phone.

8 third-party services load with your homepage (formilla.com, Google CDN and Shopify and others), adding 1.8 MB and 75 ms of main-thread time.

Shopify costs a phone 13 ms of main-thread work and 1.6 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.

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

3 KiB could be saved by minifying JavaScript.

Your largest element takes 7.0 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

The page becomes fully interactive after 7.1 s. Good is under 3.8 s.

Visually, the page fills in at 4.1 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 95 ms to 95 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 1.0 s to 1.1 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 3.1 MB in 177 requests on a phone: media 1.6 MB (1), other files 721 KiB (88) and images 454 KiB (34). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.89 g of CO₂e: 106.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

4 elements hidden from screen readers can still receive keyboard focus.

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

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 3 elements on the page fail this check, rated moderate by axe-core.

The viewport tag blocks pinch-zoom, which low-vision visitors rely on.

79 visible links have no text or label, so screen readers cannot say where they go.

1 form field has no label, so screen readers announce an empty box and autofill guesses.

ARIA role should be appropriate for the element: 3 elements on the page fail this check, rated minor by axe-core.

Alternative text of images should not be repeated as text: 2 elements on the page fail this check, rated minor by axe-core.

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

Headings skip levels (h3 → h6), which makes the page harder to scan with a screen reader.

Your title is only 13 characters: “Parts of Four”. Between 30 and 65 characters leaves room to say what you do and for whom.

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

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

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 318 pages on partsof4.com and 0 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 182 found) and read each the way a search engine does.

6 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

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.

partsof4.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.

partsof4.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.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

The homepage shows no opening hours. If customers visit or call, show when.

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 747 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 Meta Pixel, Pinterest Tag and X (Twitter) Ads (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 12 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.
