castmtb.com website review

11 images could be 603 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 1.0 s faster on a phone.

Your mobile performance score is 70. Pages that score under 90 lose visitors before the first paint.

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

Shopify costs a phone 60 ms of main-thread work and 374 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.

About 22 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 220 ms faster on a phone.

About 22 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 220 ms faster on a phone.

3 third-party services load with your homepage (Shopify, shop.app and myshopify.com), adding 392 KiB and 60 ms of main-thread time.

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

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

The page becomes fully interactive after 9.6 s. Good is under 3.8 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 0.8 s to 0.9 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Visually, the page fills in at 5.1 s (Speed Index). Good is under 3.4 s.

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

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 70 ms to 71 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

Your homepage downloads 2.6 MB in 174 requests on a phone: images 1.3 MB (20), other files 694 KiB (78) and scripts 388 KiB (67). Under 2 MB keeps phones on slow connections fast.

1 image further down the page (22 KiB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 0.73 g of CO₂e: 87.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 dropdown has no label.

2 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.

Scrollable region must have keyboard access: 1 element on the page fails this check, rated serious by axe-core.

1 image has no alt text, which hurts accessibility and image search.

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.

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

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

Elements with role="dialog" or role="alertdialog" do not have accessible names. (1 element).

1 form field has no label, so screen readers announce an empty box and autofill guesses.

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

Elements with visible text labels do not have matching accessible names. (1 element).

Your meta description is 227 characters; Google truncates after about 160, so the end of your pitch is cut.

The homepage links to 51 pages on castmtb.com and 1 external page.

Your Organization JSON-LD is missing logo, sameAs (social profiles), description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

/customer_authentication/redirect has no <title>, so Google invents the link text in results.

/customer_authentication/redirect is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

/collections/tires, /collections/grips, /collections/frontpage, /collections/handlebars, /collections/saddles-1 and /pages/contact and 2 others have no meta description, so Google writes the search snippet from whatever text it finds.

/collections, /pages/the-cast, /pages/about-us, /pages/contact and /customer_authentication/redirect have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 17 found) and read each the way a search engine does.

5 of 17 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.

2 links go through two or more redirects, for example https://castmtb.com/customer_authentication/redirect?locale=en&region_country=US.

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.

castmtb.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.

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 testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

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

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

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 260 words of visible text.

DMARC is set to p=none, so mail pretending to be castmtb.com is still delivered. Add a report address, check the reports, then move to quarantine.

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 5 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 5 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
