Usage share of web browsers

Most used web browser by country as of June 2015.^[1] In February 2016, the ranking by percentage gives:^[2]

  Google Chrome

  Safari

  Firefox

  Internet Explorer

  UC Browser

  Opera

  Android Browser

The usage share of web browsers is the proportion, often expressed as a percentage, of visitors to a group of web sites that use a particular web browser. Web browser usage share varies from region to region as well as through time. Depending on how "usage share" is defined, the results can vary greatly. In particular, page views versus unique visits will produce different results.

Accuracy

Measuring browser usage in the number of requests (page hits) made by each user agent can be misleading.

Overestimation

Not all requests are generated by a user, as a user agent can make requests at regular time intervals without user input. In this case, the user's activity might be overestimated. Some examples:

• Certain anti-virus products fake their user agent string to appear to be popular browsers. This is done to trick attack sites that might display clean content to the scanner, but not to the browser. The Register reported in June 2008 that traffic from AVG Linkscanner, using an IE6 user agent string, outstripped human link clicks by nearly 10 to 1.^[3]
• A user who revisits a site shortly after changing or upgrading browsers may be double-counted under some methods; overall numbers at the time of a new version's release may be skewed.^[4]
• Occasionally websites are written in such a way that they effectively block certain browsers. One common reason for this is that the website has been tested to work with only a limited number of browsers, and so the site owners enforce that only tested browsers are allowed to view the content, while all other browsers are sent a "failure" message, and instruction to use another browser.^[5] Many of the untested browsers may still be otherwise capable of rendering the content. Sophisticated users who are aware of this may then "spoof" the user agent string in order to gain access to the site.
• The browsers Firefox, Chrome, Safari, and Opera will under some circumstances fetch resources before they need to render them, so that the resources can be used faster if they are needed. This technique, prerendering or pre-loading, may inflate the statistics for the browsers using it because of pre-loading of resources which are not used in the end.^[6]

Underestimation

It is also possible to underestimate the usage share by using the number of requests, for example:

• Firefox 1.5 (and other Gecko-based browsers) and later versions, use fast Document Object Model (DOM) caching. JavaScript is only executed on pageload from net or disk cache, but not if it is loaded from DOM cache. This can have an impact on JavaScript-based tracking of browser statistics.^[7]
• While most browsers generate additional page hits by refreshing web pages when the user navigates back through page history, some browsers (such as Opera) reuse cached content without resending requests to the server.^[8][9]
• Generally, the more faithfully a browser implements HTTP's cache specifications, the more it will be under-reported relative to browsers that implement those specifications poorly.^[9]
• Browser users may run site, cookie and JavaScript blockers which cause those users to be under-counted. For example, common AdBlock blocklists such as EasyBlock include sites such as StatCounter in their privacy lists, and NoScript blocks all JavaScript by default. addons.mozilla.org reports 15.0 million users of AdBlock variants and 2.2 million users of NoScript.
• Users behind a caching proxy (e.g. Squid) may have repeat requests for certain pages served to the browser from the cache, rather than retrieving it again from the Internet.

User agent spoofing

Websites often include code to detect browser version to adjust the page design sent according to the user agent string received. This may mean that less-popular browsers are not sent complex content (even though they might be able to deal with it correctly) or, in extreme cases, refused all content.^[10] Thus, various browsers have a feature to cloak or spoof their identification to force certain server-side content.

• Default user agent strings of most browsers have pieces of strings from one or more other browsers, so that if the browser is unknown to a website, it can be identified as one of those. For example, Safari has not only “Mozilla/5.0”, but also “KHTML” (from which Safari’s WebKit was forked) and “Gecko” (the engine of Firefox).
• Some Ubuntu Linux browsers identify themselves as Safari in order to aid compatibility.^[11]

Differences in measurement

Net Applications, in their NetMarketShare report, uses unique visitors to measure web usage.^[12] This has the effect that users visiting a site ten times will only be counted once by these sources, while they are counted ten times by statistics companies that measure page hits.

To supplement statistics from their unique visitors measurements Net Applications uses country-level weighting.^[13] The goal of weighting countries based on their usage is to combat selection area based sampling bias caused by discrepancies in the percentage of tracked hits in the sample and the percentage of global usage documented by third party sources caused by the heavier levels of market usage.^[14]

Statistics from the United States government's Digital Analytics Program (DAP) clearly do not represent world-wide usage patterns, although at least one expert considers it the most reliable US data source.^[15] DAP uses raw data from a unified Google Analytics account.

Summary tables

According to StatCounter, as of January 2016, Chrome is not only the most popular browser on phones (or phones plus tablets)^[16] (while for tablet only browsing, Safari on iPad has 61.13%^[17] share, followed by Chrome, that inherited its engine and web standard support; Safari is not available for Android); when counting across all platforms, Chrome is also the most popular and if only desktop platforms are counted, it has more than half of that market.^[18] No desktop browser has had a clear majority for a long time, since Internet Explorer lost it and Netscape before it. Other statistics/analysts show similar numbers except for NetApplications, which shows Internet Explorer ranked first at 46.09% (with Chrome second at 35.1%) and Safari as the most popular mobile browser.

The following tables summarize the usage share of all browsers for the indicated months. For the "all browsers" stats, since all Apple Inc.'s platforms use the Safari browser, including OS X and iOS (such as in iPhone and iPad) with the WebKit engine, Safari's percentage is counting all these users.^[19]

Crossover to mobile getting more popular

According to StatCounter web use statistics, on weekends desktops worldwide lose about 5 percent points, e.g. down to 51.46% on 15 August 2015, with the loss in (relative) web use going to mobile (and also a tiny increase for tablets),^[22] mostly because Windows 7, ranked 1st on workdays, declines in web use, with it shifting to Android and lesser degree to iOS.^[23] Desktop has also been gradually losing relative market share over time. Two continents, have already crossed over to mobile-majority (because of Android), based on StatCounters web use statistics. In June 2015, Asia became the first continent where mobile overtook desktop^[24][25] (followed by Africa in August;^[26] while Nigeria had mobile majority in October 2011,^[27][28] because of Symbian – that later had 51% share, then Series 40 dominating, followed by Android as dominating operating system^[29]) and as far back as October 2014, they had reported this trend on a large scale in a press release: "Mobile usage has already overtaken desktop in several countries including India, South Africa and Saudi Arabia".^[30] In India desktop went from majority, in July 2012, down to 32%.^[31] In Bangladesh desktop went from majority, in May 2013, down to 17%, with Android alone now accounting for majority web use.^[32] Just a handful of African countries are still desktop-majority^[33] and many have a large mobile majority including Ethiopia and Kenya, where mobile usage is over 72%.^[34]

The popularity of mobile use worldwide, has been driven by the huge popularity of Android in Asian countries, where Android is highest ranked operating system in the statistics in virtually every southeast Asian country^[35] while it also ranks most popular in almost every African country, Poland, Turkey and recently Albania^[36]), have also crossed over because of vastly more popular Android devices.^[37] Android and mobile browsing in general has also gotten hugely popular in all other continents where desktop has a huge (mostly saturated) desktop base and the trend to mobile is not as clear as a fraction of the total web use.

While some analysts count tablets with desktops (as some of them run Windows), others count them with mobile phones (as the vast majority of tablets run mobile operating systems, such as Android or iOS on the iPad).

In March 2015, for the first time in the US the number of mobile-only adult internet users exceeded the number of desktop-only internet users with 11.6% of the digital population only using mobile compared to 10.6% only using desktop; this also means the majority, 78%, use both desktop and mobile to access the internet.^[38]

Historical usage share

StatCounter statistics are directly derived from hits (not unique visitors) from 3 million sites using StatCounter totaling more than 15 billion hits per month.^[39] No weightings are used.

Desktop and mobile browser usage

StatCounter reports desktop (including laptop) and mobile browser share separately. For consistency, each desktop browser share has been reduced by multiplying it by the current overall desktop share versus mobile. Similarly, mobile browser shares have each been multiplied by the overall mobile percentage. This avoids having greater than 100% usage share when combining mobile and desktop.

Net Applications (2004 Q4 to present)

Desktop browser usage share based on unique visitors in February 2015

Net Applications bases its usage share on statistics from 40,000 websites having around 160 million unique visitors per month. The mean site has 1300 unique visitors per day.

On 1 August 2009, Net Applications began weighing its raw data based on the number of internet users in the countries concerned, using data from the CIA ; the changes were applied retroactively to older data, starting with November 2007.^[40] Quarterly data prior to Q1 2008, is reported with a different methodology compared to quarterly data starting with Q1 2008, so combining these data sets and/or using them as the basis for identifying historical trends could result in flawed information.

*Net Applications no longer reports data prior to November 2007 because of this change in methodology.

Wikimedia (April 2009 to present)

Wikimedia traffic analysis reports are based on server logs of about 4 billion page requests per month, based on the user agent information that accompanied the requests.^[41] These server logs cover requests to all the Wikimedia Foundation projects, including Wikipedia, Wikimedia Commons, Wiktionary, Wikibooks, Wikiquote, Wikisource, Wikinews, Wikiversity and others.^[42]

Note^†: Wikimedia has recently had a large percentage of unrecognised browsers, previously counted as Firefox, that are now assumed to be Internet Explorer 11 fixed in the February 2014 and later numbers. And February 2014 numbers include mobile for Internet Explorer and Firefox (not included in Android). Chrome does not include the mobile numbers (Android does).

TheCounter.com identifies sixteen versions of six browsers (Internet Explorer, Firefox, Safari, Opera, Netscape, and Konqueror). Other browsers are categorised as either "Netscape compatible" (including Google Chrome, which may also be categorized as "Safari" because of its "Webkit" subtag) or "unknown". Internet Explorer 8 is identified as Internet Explorer 7. Monthly data includes all hits from 2008-02-01 until the end of the month concerned. More than the exact browser type, this data identifies the underlying rendering engine used by various browsers, and the table below aggregates them in the same column.
