Chrome UX Report (opens in a new tab): real Chrome visitors over rolling 28-day periods.
One score from every part of this review. How it works
Speed
Render-blocking requests
1.3 s6 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.3 s.
Mobile performance score: 76
76/100Your mobile performance score is 76. Pages that score under 90 lose visitors before the first paint.
Improve image delivery
422 KiB16 images could be 422 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.
8 third-party services on the page
8 third-party services load with your homepage (Affirm, Shopify and Clarity and others), adding 671 KiB and 500 ms of main-thread time.
Use efficient cache lifetimes
150 ms · 200 KiB12 files are served with short cache lifetimes, so returning visitors download them again (200 KiB).
Reduce unused JavaScript
209 KiBAbout 209 KiB of JavaScript is downloaded but never used on this page.
2 long tasks on the main thread
2 long tasks block the main thread while loading, the longest for 182 ms. During a long task the page ignores taps.
Legacy JavaScript
34 KiBPolyfills for old browsers add 34 KiB JavaScript that modern phones do not need.
Reduce unused CSS
11 KiBAbout 11 KiB of CSS is downloaded but never applied on this page.
Chained critical requests
Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.
Forced reflow
Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.
Minify CSS
4 KiB4 KiB could be saved by minifying CSS.
Minify JavaScript
3 KiB3 KiB could be saved by minifying JavaScript.

Main-thread work: 1.6 s
A phone's processor spends 1.6 s on main-thread work while loading, 908 ms of it running JavaScript. That is comfortably low.
Server response: 5 ms
5 msYour server sent the HTML in 5 ms, well inside Google's 600 ms guideline.
Core Web Vitals
First Contentful Paint: 3.8 s
3.8 sThe first text or image appears after 3.8 s on a phone. Good is under 1.8 s.
Speed Index: 6.3 s
6.3 sVisually, the page fills in at 6.3 s (Speed Index). Good is under 3.4 s.
Time to Interactive: 7.6 s
7.6 sThe page becomes fully interactive after 7.6 s. Good is under 3.8 s.
Largest Contentful Paint: 3.8 s
3.8 sYour largest element takes 3.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “We and our partners, including Shopify, use cookies and oth…”. Most of its time is element render delay (2.5 s).
27 images without width and height
27 images have no width and height attributes, so the layout jumps as each one loads.
Tap response (INP) held steady for real visitors
+2%Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 64 ms to 67 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Images and page weight
Page weight: 2.5 MB in 224 requests
2.5 MBYour homepage downloads 2.5 MB in 224 requests on a phone: images 902 KiB (44), other files 769 KiB (95) and scripts 757 KiB (73). Under 2 MB keeps phones on slow connections fast.
3 images in older formats
3 images (190 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.
About 0.7 g of CO₂ per visit
0.71 gBy the Sustainable Web Design model, a visit to your homepage emits about 0.71 g of CO₂e: 84.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Images load when needed
Images below the first screen wait until the visitor scrolls to them.
Images are sized for phones

Accessibility
Orphan list items
Some list items are not inside a list.
1 text element with low contrast
1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.
Malformed lists
Some lists contain elements other than list items, which screen readers announce wrongly.
Landmarks should have a unique role or role/label/title (i.e. accessible name) combination (1 element)
Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.
5 links without text
5 visible links have no text or label, so screen readers cannot say where they go.
2 form fields without a label
2 form fields have no label, so screen readers announce an empty box and autofill guesses.
Alternative text of images should not be repeated as text (10 elements)
Alternative text of images should not be repeated as text: 10 elements on the page fail this check, rated minor by axe-core.
Headings should not be empty (1 element)
Headings should not be empty: 1 element on the page fails this check, rated minor by axe-core.
Headings skip levels
Headings skip levels (h1 → h3), which makes the page harder to scan with a screen reader.
<td> elements in a large <table> do not have table headers.
<td> elements in a large <table> do not have table headers. (1 element).
2 checks passed
Every image has alt text
All 33 images in the HTML carry an alt attribute.
42 automated accessibility rules passed
axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 50 WCAG 2.2 A/AA and best-practice rules on the phone render: 42 passed and 8 failed. 1 more need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.
SEO
Meta description is long (198 characters)
Your meta description is 198 characters; Google truncates after about 160, so the end of your pitch is cut.
One H1 headline
Your <h1> is empty.
351 internal links, 8 external
The homepage links to 351 pages on stmtuned.com and 8 external pages.
6 checks passed
Title: 47 characters
Your title is a healthy 47 characters: “STM Tuned Inc. | Performance Tuning & OEM Parts”.
Canonical URL set
The canonical URL is https://stmtuned.com/.
Structured data in place
Structured data found: AutoPartsStore, MerchantReturnPolicy, WebPage and WebSite.
Open Graph tags complete
Open Graph tags are complete, so shared links show a title, description and image.
robots.txt in place
robots.txt is in place and points crawlers to your sitemap.
XML sitemap found
Your XML sitemap is reachable at https://stmtuned.com/sitemap.xml.
AI search readiness
No Organization structured data
There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.
3 checks passed
AI answer engines may read the site
Your robots.txt lets the crawlers behind ChatGPT search, Claude and Perplexity read the site and cite it in answers.
Text is in the HTML
Your server sends the page's text in the HTML (1,013 words), so crawlers that don't run JavaScript still read it.

Best practices
17 small tap targets
17 of 62 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.
4 JavaScript errors while loading
4 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.
1 checks passed
Mobile viewport set
The page declares a mobile viewport.
Content and conversion
No call to action on the first screen
On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.
Local business without LocalBusiness data
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.
Thin social proof
Social proof on the homepage: a star rating. Pairing it with named testimonials or customer logos makes it far more convincing.
No direct contact details
No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.
No map or directions link
There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.
No risk reducer
No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.
About 399 words of copy
The homepage carries about 399 words of visible text.
5 checks passed
8 calls to action
The homepage has 8 calls to action, for example “Sign up”, “Shop Supplies” and “Shop By Brand”.

18 cookies set on arrival
18Opening 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.
42 other companies contacted
Loading the homepage contacts 42 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
Security, domain, email and software versions
