partsmax.co website review

5 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.3 s.

Signyfyd costs a phone 1.2 s of main-thread work and 280 KiB of downloads while your page loads. That alone is enough to make taps feel slow. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

Your mobile performance score is 44. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

8 third-party services load with your homepage (Signyfyd, Google Tag Manager and Accessibe Accessibility Overlay and others), adding 1.0 MB and 1.6 s of main-thread time.

11 long tasks block the main thread while loading, the longest for 768 ms. During a long task the page ignores taps.

About 200 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 420 ms faster on a phone.

9 files are served with short cache lifetimes, so returning visitors download them again (67 KiB).

A phone's processor spends 3.4 s on main-thread work while loading, 2.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Polyfills for old browsers add 23 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

About 19 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

2 images could be 28 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

6 KiB could be saved by minifying JavaScript.

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

The first text or image appears after 6.5 s on a phone. Good is under 1.8 s.

The page becomes fully interactive after 12.4 s. Good is under 3.8 s.

Visually, the page fills in at 7.2 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 564 ms in total while the page loads. Good is under 200 ms.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 124 ms to 132 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 1.2 s to 1.4 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.2 MB in 214 requests on a phone: scripts 1.1 MB (79), other files 755 KiB (86) and images 129 KiB (19). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.62 g of CO₂e: 74.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

3 dropdowns have no label.

1 text element doesn'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.

Heading levels should only increase by one: 1 element on the page fails this check, rated moderate by axe-core.

4 form fields have no label, so screen readers announce an empty box and autofill guesses.

Your title is only 8 characters: “Partsmax”. Between 30 and 65 characters leaves room to say what you do and for whom.

Your meta description is only 66 characters: “We have been selling auto parts and accessories for over 20 years.”. 70 to 160 characters is enough to sell the click.

Structured data found (Organization, Store and WebSite) but with 1 problem, for example “WebSite: url is not an absolute URL ("partsmax.co")”.

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

Your <h1> is empty.

The homepage links to 43 pages on partsmax.co and 10 external pages.

Your homepage links to https://partsmax.co/collections/cooling, which answers with an error. Visitors hit a dead end and search engines drop it.

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

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

/ and https://partsmax.co/a/careers all use the title “Partsmax”. Search engines can't tell which page to show for a search, so each competes with the others.

https://partsmax.co/a/careers, https://partsmax.co/blogs/news, https://partsmax.co/customer_authentication/redirect, https://partsmax.co/collections/bumper, https://partsmax.co/collections/fenders and https://partsmax.co/collections/lamps and 6 others have no meta description, so Google writes the search snippet from whatever text it finds.

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

We fetched 15 pages linked from your homepage (of 22 found) and read each the way a search engine does.

16 of 29 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

2 errors were logged to the browser console while the page loaded, for example “$ is not defined”.

1 image is displayed at the wrong aspect ratio, so it looks stretched or squashed.

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 testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

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 671 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and Meta Pixel and 2 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 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 29 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
