blvck.com website review

About 448 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 900 ms faster on a phone.

8 third-party services load with your homepage (Google Tag Manager, Shopify and TikTok and others), adding 1.1 MB and 892 ms of main-thread time.

Your mobile performance score is 63. Pages that score under 90 lose visitors before the first paint.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 350 ms.

A phone's processor spends 3.2 s on main-thread work while loading, 1.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Google Tag Manager costs a phone 278 ms of main-thread work and 328 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.

Shopify costs a phone 194 ms of main-thread work and 299 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.

The page has 1,716 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

9 images could be 235 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Polyfills for old browsers add 47 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

8 long tasks block the main thread while loading, the longest for 159 ms. During a long task the page ignores taps.

14 files are served with short cache lifetimes, so returning visitors download them again (84 KiB).

About 16 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.

3 KiB could be saved by minifying JavaScript.

Your largest element takes 9.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Blvck”.

The page becomes fully interactive after 13.8 s. Good is under 3.8 s.

Visually, the page fills in at 4.8 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 332 ms in total while the page loads. Good is under 200 ms.

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 112 ms to 129 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 3.3 MB in 304 requests on a phone: scripts 1.3 MB (86), images 924 KiB (32) and other files 917 KiB (167). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.94 g of CO₂e: 113.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

17 images have no alt text, which hurts accessibility and image search.

20 visible links have no text or label, so screen readers cannot say where they go.

Alternative text of images should not be repeated as text: 11 elements on the page fail this check, rated minor by axe-core.

ARIA role should be appropriate for the element: 2 elements on the page fail this check, rated minor by axe-core.

The homepage links to 115 pages on blvck.com and 14 external pages.

/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.

/customer_authentication/redirect, /collections/mens-bottoms, /collections/mens-outerwear, /collections/womens-bottoms, /collections/activewear-women and /collections/shades-of-blvck-women have no meta description, so Google writes the search snippet from whatever text it finds.

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

We fetched 15 pages linked from your homepage (of 56 found) and read each the way a search engine does.

1 error was logged to the browser console while the page loaded, for example “Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'register')”.

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

3 links go through two or more redirects, for example https://blvck.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.

blvck.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.

blvck.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.

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 1,022 words of visible text.

DMARC is set to p=none, so mail pretending to be blvck.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.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and Meta Pixel and 2 mores (measured from a US location before any click). A consent tool (CookieYes) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 27 cookies, 1 of them by other companies (measured from a US location before any click).

Loading the homepage contacts 44 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
