protonbits.com website review

10 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.3 s.

Your mobile performance score is 47. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

67 files are served with short cache lifetimes, so returning visitors download them again (1.2 MB).

7 third-party services load with your homepage (Google Tag Manager, Facebook and Hello Bar and others), adding 887 KiB and 600 ms of main-thread time.

About 449 KiB of JavaScript is downloaded but never used on this page.

Google Tag Manager costs a phone 252 ms of main-thread work and 330 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.

A phone's processor spends 2.3 s on main-thread work while loading, 1.1 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 1,684 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

1 image could be 9 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 200 ms faster on a phone.

9 long tasks block the main thread while loading, the longest for 203 ms. During a long task the page ignores taps.

Polyfills for old browsers add 26 KiB JavaScript that modern phones do not need.

About 13 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.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

The first text or image appears after 10.0 s on a phone. Good is under 1.8 s.

Your largest element takes 10.4 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 19.0 s. Good is under 3.8 s.

Visually, the page fills in at 10.0 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 359 ms in total while the page loads. Good is under 200 ms.

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 3.3 MB in 79 requests on a phone: HTML 1.7 MB (1), scripts 1.1 MB (37) and images 351 KiB (21). Under 2 MB keeps phones on slow connections fast.

4 images (213 KiB) 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.

2 images further down the page (49 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 0.94 g of CO₂e: 113.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

9 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.

[role="img"] and [role="image"] elements must have alternative text: 8 elements on the page fail this check, rated serious by axe-core.

4 visible links have no text or label, so screen readers cannot say where they go.

ARIA role should be appropriate for the element: 6 elements on the page fail this check, rated minor by axe-core.

Your title is 70 characters, so Google will cut it off around 60: “Hire Dedicated Developers for Web, App & SaaS Development | ProtonBits”.

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

The homepage links to 65 pages on protonbits.com and 0 external pages.

Your Organization JSON-LD is missing sameAs (social profiles), description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

There is no https://www.protonbits.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.

https://www.protonbits.com/work is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

https://www.protonbits.com/hire-mobile-app-developers and https://www.protonbits.com/hire-digital-marketing-experts all use the title “Mobile App Development Company | iOS, Android, React Native & Flutter…”. Search engines can't tell which page to show for a search, so each competes with the others.

https://www.protonbits.com/work has no meta description, so Google writes the search snippet from whatever text it finds.

https://www.protonbits.com/hire-mobile-app-developers and https://www.protonbits.com/hire-digital-marketing-experts use the same meta description. A description written for each page earns more clicks.

https://www.protonbits.com/expertise, https://www.protonbits.com/case-studies, https://www.protonbits.com/work and https://www.protonbits.com/insights have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage and read each the way a search engine does.

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.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

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 495 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, HubSpot and Meta Pixel (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 13 cookies, 5 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 17 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
