Speed

9 to fix56
  • Render-blocking requests

    1.6 s

    5 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.6 s.

  • 8 third-party services on the page

    8 third-party services load with your homepage (Intercom, Cookiebot and Shopify and others), adding 1.6 MB and 977 ms of main-thread time.

  • Mobile performance score: 56

    56/100

    Your mobile performance score is 56. Pages that score under 90 lose visitors before the first paint.

  • Intercom adds 532 ms

    532 ms

    Intercom costs a phone 532 ms of main-thread work and 981 KiB 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.

  • Reduce unused JavaScript

    564 KiB

    About 564 KiB of JavaScript is downloaded but never used on this page.

  • Use efficient cache lifetimes

    400 ms · 108 KiB

    20 files are served with short cache lifetimes, so returning visitors download them again (108 KiB).

  • Main-thread work: 3.7 s

    A phone's processor spends 3.7 s on main-thread work while loading, 1.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

  • 10 long tasks on the main thread

    10 long tasks block the main thread while loading, the longest for 252 ms. During a long task the page ignores taps.

  • 2,044 HTML elements

    The page has 2,044 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

  • Reduce unused CSS

    150 ms · 42 KiB

    About 42 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.

  • Legacy JavaScript

    150 ms · 19 KiB

    Polyfills for old browsers add 19 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

  • Improve image delivery

    159 KiB

    7 images could be 159 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

  • Font display

    50 ms

    Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

  • 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.

1 checks passed
  • Server response: 7 ms

    7 ms

    Your server sent the HTML in 7 ms, well inside Google's 600 ms guideline.

Core Web Vitals

7 to fix100
  • Largest Contentful Paint: 8.1 s

    8.1 s

    Your largest element takes 8.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

  • Time to Interactive: 20.6 s

    20.6 s

    The page becomes fully interactive after 20.6 s. Good is under 3.8 s.

  • Speed Index: 7.0 s

    7.0 s

    Visually, the page fills in at 7.0 s (Speed Index). Good is under 3.4 s.

  • Total Blocking Time: 319 ms

    319 ms

    Scripts block taps and scrolling for 319 ms in total while the page loads. Good is under 200 ms.

  • Cumulative Layout Shift: 0.126

    0.126

    The layout shifts by 0.126 while loading, so content jumps under the reader's thumb. Good is under 0.1.

  • First Contentful Paint: 2.0 s

    2.0 s

    The first text or image appears after 2.0 s on a phone. Good is under 1.8 s.

  • 1 image without width and height

    1 image have no width and height attributes, so the layout jumps as each one loads.

  • Tap response (INP) got 16% slower for real visitors

    +16%

    Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 116 ms to 137 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

  • Largest content (LCP) held steady for real visitors

    -3%

    Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 1.7 s to 1.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

6 checks passed

  • Real-user CLS: 0.01

    0.01

Images and page weight

1 to fix85
  • Page weight: 3.5 MB in 218 requests

    3.5 MB

    Your homepage downloads 3.5 MB in 218 requests on a phone: scripts 1.7 MB (88), other files 799 KiB (86) and images 628 KiB (17). Under 2 MB keeps phones on slow connections fast.

  • About 1.0 g of CO₂ per visit

    0.98 g

    By the Sustainable Web Design model, a visit to your homepage emits about 0.98 g of CO₂e: 117.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

3 checks passed
  • Images use modern formats

    Every sizeable image is WebP, AVIF or SVG.

  • 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

3 to fixGoogle 9295
  • 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.

  • Zoom is disabled

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

  • Page should contain a level-one heading (1 element)

    Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

  • Elements with visible text labels do not have matching accessible names.

    Elements with visible text labels do not have matching accessible names. (2 elements).

2 checks passed
  • Every image has alt text

    All 3 images in the HTML carry an alt attribute.

  • 38 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 41 WCAG 2.2 A/AA and best-practice rules on the phone render: 38 passed and 3 failed. 2 mores need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

3 to fixGoogle 9286
  • No H1 headline

    There is no <h1>, so neither visitors nor Google get a clear main headline.

  • Only 4 internal links

    The homepage links to only 4 pages on your own site, so visitors and crawlers find few routes into the rest of it.

  • 3 links with vague text

    3 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

7 checks passed
  • Meta description: 140 characters

    Your meta description is 140 characters: “The AutoTuner Tool is the simple, fast and universal solution for ECU and TCU remapping. Master or slave, no subscripti…”.

  • Title: 52 characters

    Your title is a healthy 52 characters: “AutoTuner • ECU Reprogramming Tool for Professionals”.

  • Canonical URL set

    The canonical URL is https://www.autotuner.com/.

  • Structured data in place

    Structured data found: BreadcrumbList, Organization 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://www.autotuner.com/sitemap.xml.

AI search readiness

100
  • No llms.txt

    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.

2 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.

  • Organization data: 5 of 6 facts

    Your Organization JSON-LD gives name, url, logo, sameAs (social profiles) and description; contact details would complete it.

Other pages

2 to fix90
  • 3 pages without a meta description

    /collections/all, /policies/privacy-policy and /policies/terms-of-service have no meta description, so Google writes the search snippet from whatever text it finds.

  • 1 page without an H1

    /collections/all has no <h1> headline, so visitors and search engines get no clear main topic.

  • 3 internal pages checked

    We fetched 3 pages linked from your homepage and read each the way a search engine does.

5 checks passed
  • Linked pages load

    All 3 pages we checked loaded without an error.

  • Canonical URLs point to themselves

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

  • Titles are unique

    Every page we checked has its own title.

  • No linked page is hidden from search

    None of the pages we checked carries a noindex tag.

  • Every page has a title

    All 3 pages that loaded have a <title>.

Best practices

2 to fixGoogle 7391
  • 5 small tap targets

    5 of 15 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

  • 1 third-party cookie

    1 third-party cookie is set on load; browsers are restricting these, so whatever relies on them breaks.

  • Browser-reported issues

    Chrome logged issues while loading the page (“Cookie”).

2 checks passed
  • No console errors

    No JavaScript errors were logged while the page loaded on a phone.

  • Mobile viewport set

    The page declares a mobile viewport.

Content and conversion

6 to fix36
  • 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.

  • No calls to action

    We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

  • No social proof

    No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

  • No analytics detected

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

  • 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.

  • Only about 57 words

    The homepage has only about 57 words of visible text; thin pages give Google and first-time buyers little to go on.

  • 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.

1 checks passed
  • 2 short forms

    2 short forms (0 fields at most) are right on the homepage.

Privacy and tracking

  • 2 trackers load before any consent

    2

    Before a visitor clicks anything, the page loads Klaviyo and Snap Pixel (measured from a US location before any click). A consent tool (Cookiebot) is installed; check it blocks these until visitors agree where the law requires it.

  • 9 cookies set on arrival

    9

    Opening the homepage sets 9 cookies (measured from a US location before any click).

  • 21 other companies contacted

    Loading the homepage contacts 21 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.

1 checks passed
  • Consent tool: Cookiebot

    A consent management tool (Cookiebot) loads with the page.
