roblox.com website review

About 1.5 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 8.3 s faster on a phone.

32 files block the first paint until they finish downloading. Deferring or inlining them could save about 3.1 s.

rbxcdn.com costs a phone 1.9 s of main-thread work and 3.3 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.

Your mobile performance score is 36 (desktop: 36). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

2 third-party services load with your homepage (rbxcdn.com and Sentry), adding 3.3 MB and 1.9 s of main-thread time.

About 133 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 610 ms faster on a phone.

13 long tasks block the main thread while loading, the longest for 402 ms. During a long task the page ignores taps.

Polyfills for old browsers add 55 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 300 ms faster on a phone.

A phone's processor spends 2.9 s on main-thread work while loading, 1.2 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

1 image could be 206 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

6 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.

Real visitors wait 4.4 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors see the first content after 4.4 s (75th percentile). Good is under 1.8 s.

Your largest element takes 20.0 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

The page becomes fully interactive after 20.2 s. Good is under 3.8 s.

Visually, the page fills in at 8.5 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 4.1 s on a phone. Good is under 1.8 s.

Scripts block taps and scrolling for 1.1 s in total while the page loads. Good is under 200 ms.

Real visitors wait 996 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 287 ms to 307 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 4.1 s to 4.5 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 3.3 MB in 144 requests on a phone: scripts 2.7 MB (101), images 259 KiB (2) and stylesheets 205 KiB (23). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.95 g of CO₂e: 113.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Your meta description is 239 characters; Google truncates after about 160, so the end of your pitch is cut.

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

There is no https://www.roblox.com/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.

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: the server responded with a status of 401 ()”.

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 15 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.

Opening the homepage sets 5 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 5 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
