Browser and operating system reports show what your visitors use to reach your website: Chrome or Safari, Windows or Android, a phone or a desktop computer. These reports rarely get much attention, yet they answer practical questions. Which devices should you test on? Is a layout problem affecting many people or almost nobody? Are you losing mobile visitors? This guide explains what the reports contain, how accurate they are and how to turn them into concrete improvements.
Where the data comes from
Every browser sends a short identification text, the user agent, with each request. It names the browser, its version and the operating system. When the counter code runs, it also reads basic information such as the screen size. GNRCounter uses this information to group visits by browser and operating system and to separate mobile from desktop activity in your reports.
This information describes the software, not the person. It is used for aggregate statistics, and like other visitor data it belongs in your privacy notice.
The browser report
The browser report lists browsers such as Chrome, Safari, Edge, Firefox, Samsung Internet and Opera, with the number of visits for each in the selected period. Typical patterns:
- Chrome usually leads on both desktop and Android.
- Safari is strong where many visitors use iPhones, iPads and Macs. All browsers on iPhone use Apple’s browser engine, so Safari-related rendering issues affect most iPhone visitors whichever browser they choose.
- Edge is common in workplaces using Windows.
- In-app browsers, which open when someone taps a link inside a social or messaging app, may appear under their own names or as the underlying browser.
The operating system report
The operating system report shows Windows, macOS, Linux, Android, iOS and others. It is the quickest way to see the balance between mobile and desktop. If Android and iOS together account for most visits, your site is primarily a mobile site, whatever it looks like on your own computer.
Questions these reports answer
Which devices should I test on?
Test on the combinations that cover most of your visitors. For many sites that means Chrome on Android, Safari on iPhone and Chrome on Windows. If a less common browser has a meaningful share, add it to your test list.
Is a reported bug worth fixing urgently?
If a reader reports a problem in a specific browser, check its share. A layout issue affecting a browser with 30% of your visits is urgent; one affecting 0.5% can be scheduled, though it should still be fixed if it blocks important actions.
Am I losing mobile visitors?
Compare engagement between mobile and desktop. If mobile visitors view far fewer pages per visit than desktop visitors on the same content, the mobile experience may be the reason: small text, slow loading, intrusive pop-ups or hard-to-tap menus.
Can I rely on a modern feature?
Before using a new web feature, check whether your visitors’ browsers support it. A report showing a share of older browser versions tells you to provide a fallback.
Turning the reports into improvements
- Design for the leading device first. If most visitors are on phones, review every important page on a phone before a desktop screen.
- Check text size and tap targets. Body text of at least 16 pixels and buttons large enough to tap comfortably make a noticeable difference on mobile.
- Reduce page weight. Mobile visitors often use slower connections. Compress images, serve modern formats and remove unused scripts.
- Avoid layout shifts. Give images, embeds and ad slots fixed dimensions so content does not jump while the page loads.
- Test forms and menus. Contact forms, navigation menus and cookie notices must work smoothly on small screens.
- Re-check after changes. After a redesign, compare engagement by device before and after to confirm that no group of visitors was left behind.
Accuracy and limitations
- Reduced user agents: modern browsers deliberately share less detail, for example by freezing parts of the operating system version. Reports remain accurate at the browser and platform level, but fine-grained version data is less precise than in the past.
- Unusual identifiers: some privacy browsers present themselves as a more common browser, so they appear under that name.
- Bots: automated tools sometimes imitate common browsers. Known crawlers are recorded separately, but disguised bots can appear as ordinary browsers. A sudden rise in an old browser version is often automated traffic; see bot traffic explained.
- Small numbers: on small sites, a single visitor using an unusual setup can produce a surprising percentage. Look at counts as well as percentages.
Visible counters and devices
If you use a visible counter, check how it looks on the devices your report shows. On phones, footers and sidebars often stack into a single column, which can move the counter far down the page or squeeze it into a narrow space. Short labels and two or three statistics usually work best on small screens. Our guide to visible vs invisible counters helps you decide whether a display suits your layout at all.
Frequently asked questions
Why does my site look fine to me but visitors report problems?
You may be testing on a device that few of your visitors use. Check the browser and operating system reports and test on the leading combinations.
Why is “Linux” or an unknown system appearing?
Linux desktops are used by some visitors, and many servers and bots also identify as Linux. A sudden rise together with unusual referrers or countries can point to automated traffic.
Should I support very old browsers?
Make sure your content remains readable, but you do not need to support every modern feature in browsers that only a tiny share of visitors use.
Do in-app browsers affect my statistics?
They are counted like other browsers, but links opened inside apps often arrive without a referrer and appear as direct traffic. See direct traffic explained.
Next steps
Note your top three browsers and operating systems for the last month and test your most important pages on them. Then look at how your traffic changes over time with daily, monthly and yearly trends. If you do not have a counter yet, create one for free.
