killcrew.co website review

A phone's processor spends 10.0 s on main-thread work while loading, 3.4 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 8,553 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Your mobile performance score is 53. 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 900 ms.

8 third-party services load with your homepage (Shopify, Klaviyo and applovin.com and others), adding 1.4 MB and 741 ms of main-thread time.

20 files are served with short cache lifetimes, so returning visitors download them again (238 KiB).

About 103 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 450 ms faster on a phone.

13 long tasks block the main thread while loading, the longest for 534 ms. During a long task the page ignores taps.

About 307 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 150 ms faster on a phone.

Shopify costs a phone 338 ms of main-thread work and 892 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.

Klaviyo costs a phone 233 ms of main-thread work and 325 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.

5 images could be 79 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.

Polyfills for old browsers add 70 KiB JavaScript that modern phones do not need.

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.

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.

Visually, the page fills in at 12.8 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 20.4 s. Good is under 3.8 s.

Scripts block taps and scrolling for 969 ms in total while the page loads. Good is under 200 ms.

Your largest element takes 4.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “BANNER-RESIZEM.png”.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 82 ms to 111 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors see the first content after 1.9 s (75th percentile). Good is under 1.8 s.

2 images have no width and height attributes, so the layout jumps as each one loads.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 1.1 s to 1.2 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 3.7 MB in 593 requests on a phone: scripts 1.4 MB (200), other files 1.4 MB (339) and images 521 KiB (29). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.06 g of CO₂e: 127.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

All page content should be contained by landmarks: 3 elements on the page fail this check, rated moderate by axe-core.

Your title is only 26 characters: “Kill Crew - Fighter's Club”. Between 30 and 65 characters leaves room to say what you do and for whom.

There are 2 <h1> headlines (“” and “EVERYONE'S GOT SOMETHING TO KILL”). One clear main headline is easier for people and search engines.

Your meta description is 188 characters; Google truncates after about 160, so the end of your pitch is cut.

The homepage links to 440 pages on killcrew.co and 0 external pages.

/collections/baseball-tees, /collections/crewnecks, /collections/flannels, /collections/hoodies, /collections/long-sleeves and /collections/windbreakers and 9 others use the same meta description. A description written for each page earns more clicks.

We fetched 15 pages linked from your homepage (of 141 found) and read each the way a search engine does.

3 errors were logged to the browser console while the page loaded, for example “Suppressed error while exporting metrics: TypeError: Failed to fetch ”.

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

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.

killcrew.co 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.

Social proof on the homepage: 1 testimonial or review block. Pairing it with named testimonials or customer logos makes it far more convincing.

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

The homepage carries about 889 words of visible text.

DMARC is set to p=none, so mail pretending to be killcrew.co is still delivered. Reports are on, so moving to quarantine is the next step.

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 3 mores (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.

Opening the homepage sets 39 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 43 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
