dropbox.com website review

55 files block the first paint until they finish downloading. Deferring or inlining them could save about 7.7 s.

About 1.7 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.4 s faster on a phone.

Your mobile performance score is 32 (desktop: 44). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 5.5 s on main-thread work while loading, 3.2 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google Tag Manager, dropboxstatic.com and Facebook and others), adding 7.3 MB and 1.7 s of main-thread time.

dropboxstatic.com costs a phone 633 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.

Google Tag Manager costs a phone 726 ms of main-thread work and 1.3 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.

About 54 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.

77 files are served with short cache lifetimes, so returning visitors download them again (459 KiB).

20 long tasks block the main thread while loading, the longest for 332 ms. During a long task the page ignores taps.

cofra.me costs a phone 48 ms of main-thread work and 2.5 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.

The page has 1,601 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

1 image could be 27 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 14 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

10 KiB could be saved by minifying CSS.

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.

Real visitors wait 6.6 s for the largest content to appear (75th percentile). Good is under 2.5 s.

For real visitors the layout shifts by 0.32 (75th percentile). Good is under 0.1.

The first text or image appears after 7.7 s on a phone. Good is under 1.8 s.

Your largest element takes 12.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

The page becomes fully interactive after 41.3 s. Good is under 3.8 s.

Scripts block taps and scrolling for 1.3 s in total while the page loads. Good is under 200 ms.

Visually, the page fills in at 7.7 s (Speed Index). Good is under 3.4 s.

Real visitors wait 488 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Real visitors see the first content after 2.0 s (75th percentile). Good is under 1.8 s.

Real visitors wait 837 ms for your server to start answering (75th percentile). Good is under 800 ms.

Over the last 25 four-week periods to 2026-10-03, real Chrome visitors' tap response (inp) went from 277 ms to 288 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-03, real Chrome visitors' largest content (lcp) went from 4.3 s to 4.5 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 7.8 MB in 364 requests on a phone: scripts 4.2 MB (130), media 2.4 MB (1) and fonts 413 KiB (8). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 2.22 g of CO₂e: 266.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 button has no accessible name, so screen readers announce just “button”.

1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

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

1 element has a tabindex above 0, which scrambles the keyboard order.

ARIA role should be appropriate for the element: 1 element on the page fails this check, rated minor by axe-core.

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

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

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

The homepage links to 117 pages on dropbox.com and 32 external pages.

/early-access has no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 58 found) and read each the way a search engine does.

5 of 12 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

The page uses 1 deprecated browser API that will stop working in future browsers (“The Protected Audience API is deprecated and will be removed in a future release.”).

1 third-party cookie is set on load; browsers are restricting these, so whatever relies on them breaks.

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”).

2 links to other sites are dead, for example https://help.dropbox.com/ (404).

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.

dropbox.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.

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

A local customer looking to call finds no phone number on the homepage. Add one, ideally as a tap-to-call link.

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 shows no opening hours. If customers visit or call, show when.

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

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

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 804 words of visible text.

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.

Opening the homepage sets 9 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 6 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
