Speed
Use efficient cache lifetimes
850 ms · 181 KiB13 files are served with short cache lifetimes, so returning visitors download them again (181 KiB).
Mobile performance score: 66
66/100Your mobile performance score is 66. Pages that score under 90 lose visitors before the first paint.
Reduce unused JavaScript
690 ms · 183 KiBAbout 183 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 690 ms faster on a phone.
Render-blocking requests
750 ms3 files block the first paint until they finish downloading. Deferring or inlining them could save about 750 ms.
Improve image delivery
450 ms · 109 KiB2 images could be 109 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 450 ms faster on a phone.
8 third-party services on the page
8 third-party services load with your homepage (Facebook, cloudfront.net and Shopify and others), adding 394 KiB and 293 ms of main-thread time.
Reduce unused CSS
150 ms · 34 KiBAbout 34 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 · 23 KiBPolyfills 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.
1 long task on the main thread
1 long task block the main thread while loading, the longest for 87 ms. During a long task the page ignores taps.
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.

SEO
Meta description is long (194 characters)
Your meta description is 194 characters; Google truncates after about 160, so the end of your pitch is cut.
No social preview image

1 link crawlers can't follow
1 link has no real href, so search engines can't follow it.

Other pages
1 page without a title
https://magnusonsuperchargers.com/customer_authentication/redirect has no <title>, so Google invents the link text in results.
1 linked page hidden from search
https://magnusonsuperchargers.com/customer_authentication/redirect is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.
13 pages without a meta description
https://magnusonsuperchargers.com/collections/merchandise, https://magnusonsuperchargers.com/customer_authentication/redirect, https://magnusonsuperchargers.com/collections/cadillac, https://magnusonsuperchargers.com/collections/cts-v, https://magnusonsuperchargers.com/collections/escalade and https://magnusonsuperchargers.com/collections/chevrolet and 7 others have no meta description, so Google writes the search snippet from whatever text it finds.
1 page without an H1
https://magnusonsuperchargers.com/customer_authentication/redirect has no <h1> headline, so visitors and search engines get no clear main topic.

Content and conversion
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.
Only about 144 words
The homepage has only about 144 words of visible text; thin pages give Google and first-time buyers little to go on.
No opening hours
The homepage shows no opening hours. If customers visit or call, show when.
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.
6 checks passed

11 cookies set on arrival
11Opening the homepage sets 11 cookies (measured from a US location before any click).

20 other companies contacted

Security, domain, email and software versions
