Speed
Reduce unused JavaScript
1.4 s · 267 KiBAbout 267 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.4 s faster on a phone.
Mobile performance score: 44
44/100Your 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 on the page
8 third-party services load with your homepage (Google CDN, Other Google APIs/SDKs and Klaviyo and others), adding 1.1 MB and 854 ms of main-thread time.
Render-blocking requests
750 ms10 files block the first paint until they finish downloading. Deferring or inlining them could save about 750 ms.
Improve image delivery
200 ms · 266 KiB6 images could be 266 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 200 ms faster on a phone.
Google CDN adds 357 ms
357 msGoogle CDN costs a phone 357 ms of main-thread work and 329 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.
Main-thread work: 3.7 s
A phone's processor spends 3.7 s on main-thread work while loading, 1.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.
8 long tasks on the main thread
8 long tasks block the main thread while loading, the longest for 252 ms. During a long task the page ignores taps.
2,197 HTML elements
The page has 2,197 HTML elements. Above 1,500, rendering and every interaction get slower on phones.
Use efficient cache lifetimes
200 ms · 59 KiB13 files are served with short cache lifetimes, so returning visitors download them again (59 KiB).
Reduce unused CSS
150 ms · 32 KiBAbout 32 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
28 KiBPolyfills for old browsers add 28 KiB JavaScript that modern phones do not need.
Minify JavaScript
10 KiB10 KiB could be saved by minifying JavaScript.
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.

Server response: 7 ms
7 msYour server sent the HTML in 7 ms, well inside Google's 600 ms guideline.
Core Web Vitals
Fails Core Web Vitals for real visitors
Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.
Largest Contentful Paint: 16.2 s
16.2 sYour largest element takes 16.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.
Time to Interactive: 16.5 s
16.5 sThe page becomes fully interactive after 16.5 s. Good is under 3.8 s.
Speed Index: 8.5 s
8.5 sVisually, the page fills in at 8.5 s (Speed Index). Good is under 3.4 s.
First Contentful Paint: 4.0 s
4.0 sThe first text or image appears after 4.0 s on a phone. Good is under 1.8 s.
Real-user CLS: 0.23
0.23For real visitors the layout shifts by 0.23 (75th percentile). Good is under 0.1.
Cumulative Layout Shift: 0.182
0.182The layout shifts by 0.182 while loading, so content jumps under the reader's thumb. Good is under 0.1.
Total Blocking Time: 312 ms
312 msScripts block taps and scrolling for 312 ms in total while the page loads. Good is under 200 ms.
6 images without width and height
6 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 120 ms to 121 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Images and page weight
Page weight: 3.5 MB in 310 requests
3.5 MBYour homepage downloads 3.5 MB in 310 requests on a phone: images 1.2 MB (61), scripts 1.1 MB (105) and other files 756 KiB (88). Under 2 MB keeps phones on slow connections fast.
About 1.0 g of CO₂ per visit
1.00 gBy the Sustainable Web Design model, a visit to your homepage emits about 1.00 g of CO₂e: 120.5 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
48 text elements with low contrast
48 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.
Frames without titles
1 frame has no title, so screen-reader users cannot tell what it contains.
70 images without alt text
70 images have no alt text, which hurts accessibility and image search.
1 form field without a label
1 form field has no label, so screen readers announce an empty box and autofill guesses.
Headings skip levels
Headings skip levels (h1 → h3), which makes the page harder to scan with a screen reader.
1 checks passed
51 automated accessibility rules passed
axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 53 WCAG 2.2 A/AA and best-practice rules on the phone render: 51 passed and 2 failed. 3 mores need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.
SEO
Title is long (83 characters)
Your title is 83 characters, so Google will cut it off around 60: “Catalytic Converters - Mufflers - Exhausts | Muffler Express – Muffler Express Ltd.”.
Meta description is long (299 characters)
Your meta description is 299 characters; Google truncates after about 160, so the end of your pitch is cut.
No favicon declared
No favicon is declared in the HTML, so browser tabs and Google's mobile results may show a generic icon.
One H1 headline
Your <h1> is empty.
211 internal links, 13 external
The homepage links to 211 pages on mufflerexpress.com and 13 external pages.
5 checks passed
Canonical URL set
The canonical URL is https://mufflerexpress.com/.
Structured data in place
Structured data found: 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://mufflerexpress.com/sitemap.xml.
AI search readiness
No llms.txt
There is no https://mufflerexpress.com/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.
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.
Organization data: 4 of 6 facts
Your Organization JSON-LD gives name, url, logo and sameAs (social profiles); description and contact details would complete it.
Text is in the HTML
Your server sends the page's text in the HTML (795 words), so crawlers that don't run JavaScript still read it.
Other pages
1 page without a meta description
https://mufflerexpress.com/collections/catalytic-converters-freightliner has no meta description, so Google writes the search snippet from whatever text it finds.
15 internal pages checked
We fetched 15 pages linked from your homepage (of 112 found) and read each the way a search engine does.
6 checks passed
Linked pages load
6 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.
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
All 6 pages that loaded have a <title>.
Best practices
70 distorted images
70 images are displayed at the wrong aspect ratio, so they look stretched or squashed.
2 small tap targets
2 of 7 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.
3 JavaScript errors while loading
3 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.
No social proof
No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.
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.
No phone number on the homepage
A local customer looking to call finds no phone number on the homepage. Add one, ideally as a tap-to-call link.
No analytics detected
No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.
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 1,237 words of copy
The homepage carries about 1,237 words of visible text.
4 checks passed
3 calls to action
The homepage has 3 calls to action, for example “Contact Us” and “Order Tracking”.
5 short forms
5 short forms (1 field at most) are right on the homepage.
Direct contact links
Visitors can reach you directly: 0 phone links and 1 email link.
Opening hours shown
Your opening hours are on the homepage.
Privacy and tracking
5 trackers load before any consent
5Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and Meta Pixel (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.
14 cookies set on arrival
14Opening the homepage sets 14 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.
33 other companies contacted
Loading the homepage contacts 33 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 mufflerexpress.com, because details like these could help someone attack a site. Every review keeps them private, whatever they found.
