zumbrotadrivetrain.com website review

About 213 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.1 s faster on a phone.

Your mobile performance score is 64. Pages that score under 90 lose visitors before the first paint.

12 files block the first paint until they finish downloading. Deferring or inlining them could save about 300 ms.

The page has 1,944 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

8 third-party services load with your homepage (avada.io, myconvermax.com and Shopify and others), adding 593 KiB and 187 ms of main-thread time.

6 files are served with short cache lifetimes, so returning visitors download them again (78 KiB).

1 image could be 45 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 150 ms faster on a phone.

2 long tasks block the main thread while loading, the longest for 69 ms. During a long task the page ignores taps.

About 17 KiB of CSS is downloaded but never applied on this page.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

Your largest element takes 11.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Zumbrota Drivetrain”.

Visually, the page fills in at 6.2 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 3.0 s on a phone. Good is under 1.8 s.

By the Sustainable Web Design model, a visit to your homepage emits about 0.49 g of CO₂e: 58.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

6 form fields have no label, so screen readers announce an empty box and autofill guesses.

Headings skip levels (h3 → h5, h3 → h6 and h2 → h6), which makes the page harder to scan with a screen reader.

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

Your title is only 19 characters: “Zumbrota Drivetrain”. Between 30 and 65 characters leaves room to say what you do and for whom.

Your meta description is 272 characters; Google truncates after about 160, so the end of your pitch is cut.

Structured data found (Organization, WebPage and WebSite) but with 1 problem, for example “Organization: logo is not an absolute URL ("//www.zumbrotadrivetrain.com/cdn/shop/files/zumbrota_fa…”.

The homepage links to 207 pages on zumbrotadrivetrain.com and 7 external pages.

/collections/transfer-case-gaskets-sealing and /collections/transmission-gaskets-sealing-systems all use the title “Gaskets and Sealing Systems”. Search engines can't tell which page to show for a search, so each competes with the others.

/pages/contact, /collections/transfer-case-assembly, /collections/transfer-case-components, /collections/driveline-service-kits, /collections/transfer-case-gaskets-sealing and /collections/transfer-case-motors and 8 others use the same meta description. A description written for each page earns more clicks.

We fetched 15 pages linked from your homepage (of 63 found) and read each the way a search engine does.

7 of 28 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

HSTS is set, but max-age is 91 days; one year is the recommended minimum.

1 link go through two or more redirects, for example https://pro.randysworldwide.com/.

No Referrer-Policy header, so full URLs can leak to the sites you link to.

No Permissions-Policy header to switch off camera, microphone and location for embedded content.

X-XSS-Protection is set to “1; mode=block”; the header is deprecated and can introduce bugs. Use 0 or remove it.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

zumbrotadrivetrain.com has no CAA record, so any certificate authority may issue a certificate for it. A CAA record naming your provider (for example letsencrypt.org) closes that door.

zumbrotadrivetrain.com's DNS answers are not signed. DNSSEC stops attackers forging them to send visitors or email elsewhere; most registrars switch it on in a click, though most sites still run without it.

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

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 analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

The homepage shows no opening hours. If customers visit or call, show when.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

The homepage carries about 395 words of visible text.

We found no DKIM key on the selectors the big email providers use. If you send through one of them, turning on DKIM signing improves delivery.

Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

Opening the homepage sets 7 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.

Loading the homepage contacts 15 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
