atlassian.com website review

About 2.4 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 8.8 s faster on a phone.

atl-paas.net costs a phone 3.3 s of main-thread work and 3.0 MB 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.

A phone's processor spends 11.2 s on main-thread work while loading, 7.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Your mobile performance score is 26 (desktop: 30). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

The page has 6,674 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

8 third-party services load with your homepage (atl-paas.net, Google Tag Manager and Google CDN and others), adding 5.3 MB and 4.6 s of main-thread time.

5 images could be 2.5 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

35 files are served with short cache lifetimes, so returning visitors download them again (703 KiB).

Google Tag Manager costs a phone 541 ms of main-thread work and 857 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.

20 long tasks block the main thread while loading, the longest for 584 ms. During a long task the page ignores taps.

83 KiB JavaScript is shipped twice across bundles. Google estimates it would make the page about 450 ms faster on a phone.

Google CDN costs a phone 220 ms of main-thread work and 733 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.

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

About 119 KiB of CSS is downloaded but never applied on this page.

Polyfills for old browsers add 32 KiB JavaScript that modern phones do not need.

12 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.

4 KiB could be saved by minifying JavaScript.

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.

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

Your homepage downloads 13.7 MB in 333 requests on a phone: scripts 5.5 MB (81), images 4.3 MB (150) and media 2.8 MB (5). Under 2 MB keeps phones on slow connections fast.

5 images (1.0 MB) 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.

By the Sustainable Web Design model, a visit to your homepage emits about 3.88 g of CO₂e: 465.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

12 tap targets are too small or too close together to hit reliably with a finger.

4 elements hidden from screen readers can still receive keyboard focus.

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

Your title is 70 characters, so Google will cut it off around 60: “Collaboration software for software, IT and business teams | Atlassian”.

Structured data found (Organization, SoftwareApplication, WebPage and WebSite) but with 4 problems, for example “SoftwareApplication: no offers (price) block”.

No favicon is declared in the HTML, so browser tabs and Google's mobile results may show a generic icon.

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

The homepage links to 194 pages on atlassian.com and 28 external pages.

/software, /software/jira, /software/confluence, /software/jira/service-management, /collections/teamwork and /collections/strategy and 8 others have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 70 found) and read each the way a search engine does.

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

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

The page has no <!DOCTYPE html>, so browsers render it in quirks mode.

Large scripts ship without source maps.

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

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.

atlassian.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.

Social proof on the homepage: 2 trust badges. 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.

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 756 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 Google Ads, Google Analytics, Google Tag Manager, LinkedIn Insight and Meta Pixel and 4 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 22 cookies (measured from a US location before any click).

Loading the homepage contacts 42 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
