bfdsystems.com website review

46 files are served with short cache lifetimes, so returning visitors download them again (2.8 MB).

About 1.4 MB of JavaScript is downloaded but never used on this page.

6 third-party services load with your homepage (Google CDN, Vimeo and Google Tag Manager and others), adding 4.0 MB and 818 ms of main-thread time.

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

Google CDN costs a phone 434 ms of main-thread work and 736 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 files block the first paint until they finish downloading. Deferring or inlining them could save about 500 ms.

Vimeo costs a phone 199 ms of main-thread work and 2.9 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.

A phone's processor spends 3.7 s on main-thread work while loading, 2.1 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

About 61 KiB of CSS is downloaded but never applied on this page. 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 200 ms).

18 long tasks block the main thread while loading, the longest for 157 ms. During a long task the page ignores taps.

2 images could be 72 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Polyfills for old browsers add 39 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.

The page becomes fully interactive after 29.0 s. Good is under 3.8 s.

Visually, the page fills in at 9.5 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 2.1 s to 2.3 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your largest element takes 3.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Practical innovation, grounded in safety - we're redefining…”. Most of its time is element render delay (1.6 s).

Scripts block taps and scrolling for 373 ms in total while the page loads. Good is under 200 ms.

The first text or image appears after 2.3 s on a phone. Good is under 1.8 s.

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

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 7.0 MB in 92 requests on a phone: scripts 2.4 MB (34), images 1.8 MB (18) and media 1.3 MB (1). Under 2 MB keeps phones on slow connections fast.

1 image is downloaded at several times the size a phone draws it, for example logo-yellow-web.png at 1,983 px wide, shown at 69 px. Resized copies would save about 58 KiB.

1 image (59 KiB) is 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.

By the Sustainable Web Design model, a visit to your homepage emits about 1.99 g of CO₂e: 238.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Headings skip levels (h1 → h6, h2 → h6 and h3 → h6), which makes the page harder to scan with a screen reader.

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

The homepage links to 36 pages on bfdsystems.com and 12 external pages.

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.

/blog has no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 13 pages linked from your homepage and read each the way a search engine does.

2 third-party cookies are set on load; browsers are restricting these, so whatever relies on them breaks.

The page uses 1 deprecated browser API that will stop working in future browsers (“Unload event listeners are deprecated and will be removed.”).

3 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”).

1 link to other sites is dead, for example https://drone-amplified.odoo.com/shop/ignis-ii-10269 (404).

No Strict-Transport-Security header, so browsers may still try plain http first on a return visit.

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

The server only offers HTTP/1.1, so browsers open several connections and load files more slowly. Most hosts and CDNs turn on HTTP/2 with a setting.

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

X-Content-Type-Options: nosniff is missing, so browsers may guess file types.

Opening https://bfdsystems.com goes through 2 redirects before the homepage loads.

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.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

droneamplified.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.

droneamplified.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.

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

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.

The homepage carries about 552 words of visible text.

bfdsystems.com has no DMARC record, so nothing tells receivers what to do with mail that fails SPF or DKIM. Gmail and Yahoo require DMARC from bulk senders.

We found no DKIM key on the selectors the big email providers use. If you send through one of them, turning on DKIM signing improves delivery.

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 Analytics and Google Tag Manager (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 5 cookies, 3 of them by other companies (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 13 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
