bk.com website review

46 files are served with short cache lifetimes, so returning visitors download them again (3.0 MB).

About 2.4 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 13.3 s faster on a phone.

Your mobile performance score is 27 (desktop: 35). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 8.4 s on main-thread work while loading, 4.7 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google Tag Manager, Facebook and Google Maps and others), adding 2.0 MB and 1.6 s of main-thread time.

20 long tasks block the main thread while loading, the longest for 1.7 s. During a long task the page ignores taps.

Google Tag Manager costs a phone 830 ms of main-thread work and 827 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.

Google Maps costs a phone 126 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.

Polyfills for old browsers add 55 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 150 ms).

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 150 ms.

1 image could be 32 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

About 18 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.

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.

Real visitors wait 6.7 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors wait 641 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Your largest element takes 40.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Burger King Whopper with the text: Whopper Wednesday”.

Visually, the page fills in at 17.7 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 41.0 s. Good is under 3.8 s.

Scripts block taps and scrolling for 3.6 s in total while the page loads. Good is under 200 ms.

The first text or image appears after 4.5 s on a phone. Good is under 1.8 s.

Over the last 25 four-week periods to 2026-10-03, real Chrome visitors' largest content (lcp) went from 5.7 s to 7.1 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors see the first content after 3.0 s (75th percentile). Good is under 1.8 s.

Over the last 25 four-week periods to 2026-10-03, real Chrome visitors' tap response (inp) went from 463 ms to 526 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 5.6 MB in 214 requests on a phone: scripts 4.7 MB (52), fonts 609 KiB (5) and other files 173 KiB (129). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.57 g of CO₂e: 189.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

ARIA progressbar nodes must have an accessible name: 1 element on the page fails this check, rated serious by axe-core.

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

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

No meta description, so Google writes its own snippet from whatever text it finds.

There is no <h1>, so neither visitors nor Google get a clear main headline.

Your title is only 11 characters: “Burger King”. Between 30 and 65 characters leaves room to say what you do and for whom.

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

No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.

No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

No XML sitemap at https://www.bk.com/sitemap.xml, so Google discovers your pages only by following links.

There is no robots.txt at bk.com/robots.txt, the first file search crawlers ask for.

The homepage links to only 0 pages on your own site, so visitors and crawlers find few routes into the rest of it.

1 link use generic text like “click here” or “learn more”, which tells Google nothing about the page behind it.

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

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.

Large scripts ship without source maps.

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.

bk.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.

bk.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.

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

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.

The homepage has only about 68 words of visible text; thin pages give Google and first-time buyers little to go on.

There is no form on the homepage, so every lead has to click through to another page first.

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

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 Amplitude, Google Ads, Google Tag Manager, Meta Pixel and Microsoft Ads and 2 mores (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 4 cookies (measured from a US location before any click).

Loading the homepage contacts 19 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
