chiefs.com website review

74 files are served with short cache lifetimes, so returning visitors download them again (1.8 MB).

About 986 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.8 s faster on a phone.

5 images could be 571 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 1.9 s faster on a phone.

About 139 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 1.2 s faster on a phone.

5 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.2 s.

Integral Ad Science costs a phone 1.0 s of main-thread work and 743 KiB of downloads while your page loads. That alone is enough to make taps feel slow. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

Your mobile performance score is 17. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 5.6 s on main-thread work while loading, 3.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 3,219 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

8 third-party services load with your homepage (Integral Ad Science, Google/Doubleclick Ads and Optanon and others), adding 2.8 MB and 2.4 s of main-thread time.

Google/Doubleclick Ads costs a phone 924 ms of main-thread work and 1.1 MB 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.

20 long tasks block the main thread while loading, the longest for 257 ms. During a long task the page ignores taps.

nfltags.com costs a phone 100 ms of main-thread work and 371 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.

Polyfills for old browsers add 26 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

44 KiB JavaScript is shipped twice across bundles.

7 KiB could be saved by minifying JavaScript.

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

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.

Your largest element takes 19.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “By clicking any of the buttons in this banner, or by clicki…”.

The page becomes fully interactive after 33.5 s. Good is under 3.8 s.

The layout shifts by 0.802 while loading, so content jumps under the reader's thumb. Good is under 0.1.

The first text or image appears after 5.4 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 11.1 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 625 ms in total while the page loads. Good is under 200 ms.

Real visitors wait 3.4 s for the largest content to appear (75th percentile). Good is under 2.5 s.

For real visitors the layout shifts by 0.17 (75th percentile). Good is under 0.1.

Real visitors see the first content after 2.7 s (75th percentile). Good is under 1.8 s.

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

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 108 ms to 107 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 2.6 s to 2.8 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 5.5 MB in 290 requests on a phone: scripts 2.5 MB (102), images 1.7 MB (86) and fonts 733 KiB (25). Under 2 MB keeps phones on slow connections fast.

wcrfpdxtr9jrs7lc0ics.png weighs 696 KiB. On a phone connection a single image that size takes seconds.

2 images (834 KiB) are JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

2 images further down the page (159 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 1.55 g of CO₂e: 186.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Elements must only use permitted ARIA attributes: 2 elements on the page fail this check, rated serious by axe-core.

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

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

All page content should be contained by landmarks: 2 elements on the page fail this check, rated moderate by axe-core.

1 visible link has no text or label, so screen readers cannot say where it goes.

ARIA role should be appropriate for the element: 4 elements on the page fail this check, rated minor by axe-core.

Elements marked as presentational should be consistently ignored: 2 elements on the page fail this check, rated minor by axe-core.

Elements with visible text labels do not have matching accessible names. (55 elements).

Headings skip levels (h1 → h3 and h2 → h4), which makes the page harder to scan with a screen reader.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

There are 2 <h1> headlines (“Chiefs Home | Chiefs.com” and “CHIEFS MOBILE APP”). One clear main headline is easier for people and search engines.

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

6 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

The homepage links to 137 pages on chiefs.com and 80 external pages.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

There is no /llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

Your homepage links to 2 pages by a URL that isn't their canonical one, for example /stadium/index, whose canonical is /stadium. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

We fetched 15 pages linked from your homepage (of 101 found) and read each the way a search engine does.

17 of 49 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

4 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

Chrome logged issues while loading the page (“Cookie”).

http://chiefs.com does not redirect to https, so some visitors land on the insecure version.

1 link to other sites is dead, for example https://am.ticketmaster.com/chiefs/buy/2026StyleLounge (903).

No Content-Security-Policy header, the main browser-side defence against injected scripts.

Neither X-Frame-Options nor a CSP frame-ancestors policy is set, so any site can embed yours in a frame.

2 links go through two or more redirects, for example https://newstadium.chiefs.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.

chiefs.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.

chiefs.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 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 1,977 words of visible text.

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 Amazon Ads, Google Ads and The Trade Desk (measured from a US location before any click). A consent tool (OneTrust) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 5 cookies (measured from a US location before any click).

Loading the homepage contacts 38 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
