Speed

3 to fix76
  • Render-blocking requests

    1.3 s

    6 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.3 s.

  • Mobile performance score: 76

    76/100

    Your mobile performance score is 76. Pages that score under 90 lose visitors before the first paint.

  • Improve image delivery

    422 KiB

    16 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 KiB

    12 files are served with short cache lifetimes, so returning visitors download them again (200 KiB).

  • Reduce unused JavaScript

    209 KiB

    About 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 KiB

    Polyfills for old browsers add 34 KiB JavaScript that modern phones do not need.

  • Reduce unused CSS

    11 KiB

    About 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 KiB

    4 KiB could be saved by minifying CSS.

  • Minify JavaScript

    3 KiB

    3 KiB could be saved by minifying JavaScript.

2 checks passed
  • 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 ms

    Your server sent the HTML in 5 ms, well inside Google's 600 ms guideline.

Core Web Vitals

5 to fix100
  • First Contentful Paint: 3.8 s

    3.8 s

    The 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 s

    Visually, the page fills in at 6.3 s (Speed Index). Good is under 3.4 s.

  • Time to Interactive: 7.6 s

    7.6 s

    The page becomes fully interactive after 7.6 s. Good is under 3.8 s.

  • Largest Contentful Paint: 3.8 s

    3.8 s

    Your 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).

  • Largest content (LCP) held steady for real visitors

    +1%

    Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 0.9 s to 0.9 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

    0.00

    For real visitors the layout shifts by 0.00 (75th percentile). Good is under 0.1.

  • Real-user FCP: 1.2 s

    1.2 s

  • Real-user TTFB: 650 ms

    650 ms

    Real visitors wait 650 ms for your server to start answering (75th percentile). Good is under 800 ms.

Images and page weight

1 to fix85
  • Page weight: 2.5 MB in 224 requests

    2.5 MB

    Your 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 g

    By 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.

2 checks passed
  • Images load when needed

    Images below the first screen wait until the visitor scrolls to them.

  • Images are sized for phones

    No image is downloaded at more than three times the size it is drawn on a phone.

Accessibility

8 to fixGoogle 8589
  • 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

2 to fixGoogle 9290
  • 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

1 to fix88
  • 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.

  • llms.txt published

    The site publishes https://stmtuned.com/llms.txt (6 KiB, 8 links), a plain-text guide to the site for AI tools.

Other pages

100
  • 15 internal pages checked

    We fetched 15 pages linked from your homepage (of 194 found) and read each the way a search engine does.

7 checks passed
  • Linked pages load

    5 pages of 15 loaded without an error (the rest turned automated requests away).

  • Canonical URLs point to themselves

    No page we checked hands its ranking to a different URL.

  • Every page has a meta description

    All 5 pages that loaded have a meta description.

  • Titles are unique

    Every page we checked has its own title.

  • Every page has an H1

    Each page we checked has a main headline.

  • No linked page is hidden from search

    None of the pages we checked carries a noindex tag.

  • Every page has a title

Best practices

2 to fixGoogle 9687
  • 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

4 to fix72
  • 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”.

  • 2 short forms

    2 short forms (1 field at most) are right on the homepage.

  • Analytics in place

    Analytics detected: Microsoft Clarity.

  • Opening hours shown

    Your opening hours are on the homepage.

  • Phone number on the homepage

    Your phone number is on the homepage.

Privacy and tracking

1 to fix
  • 7 trackers load before any consent

    7

    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.

  • 18 cookies set on arrival

    18

    Opening the homepage sets 18 cookies (measured from a US location before any click).

  • No consent tool detected

    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

The security, domain and email checks, software and plugin versions, and any app with a known security problem are visible only to people at stmtuned.com, because details like these could help someone attack a site. Every review keeps them private, whatever they found.
