Wikipedia:Awareness statistics

This page is part of the Statistics family of pages. It attempts to measure the growth in public awareness of Wikipedia. Please see Modelling Wikipedia's growth for speculation on the trends in these statistics.

It is interesting to compare the following graphs with the graphs in Size of Wikipedia.

Weekly and daily rankings
Alexa traffic ranking to main English Wikipedia site – lower is better, 1 is theoretically the most popular site on the Internet. Alexa users are a self-selecting group, so they do not necessarily represent all Internet users in the correct proportions.

For comparison purposes, a snapshot of the one-week top 10 sites, as ranked by Alexa on 2 March 2007, together with their corresponding one-week reach and page views figures, was as follows: Reach  P.Views     R/W    V/W 1    yahoo.com       26.8      6.0       4.25   13.3 2    msn.com         30.1      3.6       4.78    8.0 3    google.com      25.1      2.3       3.98    5.1 4    youtube.com      8.9      1.6       1.41    3.6 5    myspace.com      4.4      2.4       0.70    5.3 6    live.com        14.6      0.63      2.32    1.3 7    baidu.com        6.1      1.2       0.97    2.7 8    qq.com           5.3      0.73      0.84    1.6 9    orkut.com        2.6      1.4       0.41    3.1 10    wikipedia.org    6.3      0.45      1       1 11    yahoo.co.jp      2.8      0.93      0.44    2.1 Where reach and views figures are percents, and R/W and V/W are the reach and views figures, normalized so that that of Wikipedia = 1. Note that Alexa does not rank by reach or views alone: their rank criterion is based on a combination of the two.

However, for a short time most days the gap is two days, as the statistics are usually updated before the graphs.'''  22 October 2002, 9,653 27 October 2002, 9,440 3 November 2002, 9,047 13 November 2002, 8,356 22 November 2002, 7,922 1 December 2002, 7,543 10 January 2003, 14,882 (major slip) 1 February 2003, 7,897 (recovering again) 7 February 2003, 6,799 (still recovering) 15 February 2003, 5,406 23 February 2003, 5,228 4 March 2003,   7,328 11 March 2003,   5,713 13 March 2003,   4,735  (continuing rise, perhaps helped by boost in Google ranking) 15 March 2003,   3,662 17 March 2003,   3,342 28 March 2003,   3,653 6 April 2003,   3,072 12 April 2003,   3,444 16 April 2003,   3,785 28 April 2003,   3,422 6 May 2003,     3,832 18 May 2003,     3,212 22 May 2003,     2,965 29 May 2003,     2,509  (possibly driven by Earthlink E-mail newsletter publicity) 16 June 2003,    3,289 23 June 2003,    3,187 2 July 2003,    2,676 13 July 2003,    2,033 17 July 2003,    2,045 8 August 2003,  1,406 2 October 2003,   941 21 October 2003, 1,038 29 October 2003, 1,189  (recent reduction in rank probably due to server problems) 3 November 2003, 1,168 13 November 2003,  906  (performance is better after load-balancing installed) 25 November 2003,  934  (ranking continues to be around 1000 +/- 100) 3 December 2003,  950  (but new server has been installed; so expect better ranking soon?) 6 December 2003,  887 8 December 2003,  838 12 December 2003,  828 15 December 2003,  751* 1 January 2004, 1,114  (a big drop back after Christmas and two major server outages) 12 January 2004,   851  (even when running slowly on backup hardware!) 24 January 2004,   778 28 January 2004,   742* 1 February 2004,  874 14 February 2004,  779 20 February 2004,  816 27 February 2004,  712* 3 March 2004,     723 8 March 2004,     678* 14 March 2004,     654* 20 March 2004,     649* 21 March 2004,     643* 25 March 2004,     634* 30 March 2004,     619* 2 April 2004,     608* 9 April 2004,     646 16 April 2004,     605* 22 April 2004,     607 23 April 2004,     596* 30 April 2004,     661 1 May 2004,       686  (hardware problems are causing a drop in traffic) 10 May 2004,       676  (continued poor traffic) 12 May 2004,       628  (making a comeback) 13 May 2004,       617 14 May 2004,       582 16 May 2004,       556* 19 May 2004,       563 20 May 2004,       558 24 May 2004,       598 27 May 2004,       619 1 June 2004,      609 2 June 2004,      538* 6 June 2004,      567 8 June 2004,      591 16 June 2004,      694 22 June 2004,      709 23 June 2004,      687 24 June 2004,      658 29 June 2004,      653 4 July 2004,      671 12 July 2004,      654 16 July 2004,      616 19 July 2004,      600 22 July 2004,      570 25 July 2004,      531 27 July 2004,      503* 28 July 2004,      487* 31 July 2004,      499 1 August 2004,    536  (taking odd nosedive) 4 August 2004,    583 13 August 2004,    647  (dropping back again) 23 August 2004,    595 31 August 2004,    506  (after adding 4 new servers) 2 September 2004, 482* 3 September 2004, 475* 4 September 2004, 463* 8 September 2004, 458* 9 September 2004, 450* 10 September 2004, 446* 12 September 2004, 424* 14 September 2004, 427 15 September 2004, 433 20 September 2004, 457 21 September 2004, 451 22 September 2004, 437 23 September 2004, 437 24 September 2004, 429 25 September 2004, 423* 26 September 2004, 419* 27 September 2004, 417* 29 September 2004, 414* 30 September 2004, 409* October 2004 spike in activity probably caused by 2004 U.S. presidential election 4 October 2004,   398*  (top 400) 5 October 2004,   383*  (daily: 290*) 6 October 2004,   361* 7 October 2004,   323*  (daily: 250*) 8 October 2004,   303* 9 October 2004,   290*  (top 300) 11 October 2004,   293 12 October 2004,   288* 13 October 2004,   280*  (daily: 231*) 14 October 2004,   271*  (daily: 218*) 15 October 2004,   254*  (daily: 197*) 16 October 2004,   251* 17 October 2004,   243* 18 October 2004,   239* 19 October 2004,   237* 20 October 2004,   231* 21 October 2004,   233 22 October 2004,   238 23 October 2004,   237 25 October 2004,   226* 26 October 2004,   222* 27 October 2004,   221* 31 October 2004,   235 9 November 2004,  238 12 November 2004,  227 16 November 2004,  222 17 November 2004,  217* 18 November 2004,  210* (daily: 172*) 19 November 2004,  208* 20 November 2004,  196* (top 200, daily: 158*) 21 November 2004,  183* 22 November 2004,  175* 23 November 2004,  167* (daily: 152*) 24 November 2004,  171 25 November 2004,  168 29 November 2004,  178 5 December 2004,  174 10 December 2004,  166* (daily: 153) 22 December 2004,  191  (daily: 161) 29 December 2004,  204  (daily: 159) January 2005 spike in activity probably caused by 2004 Indian Ocean earthquake 1 January 2005,   187  (daily: 143*) 2 January 2005,   165* 3 January 2005,   156* (daily: 140*) 4 January 2005,   147* (daily: 132*) 6 January 2005,   143* (daily: 130*) 13 January 2005,   141* 18 January 2005,   168  (daily: 192) -

Alexa Global Top 500 (3 month ranking)


In October 2004, Wikipedia appeared in Alexa's list of the Global Top 500 web sites. Note: the Alexa 3 month ranking is based on a three-month moving average, so it will smooth out both temporary peaks and temporary troughs in performance. Now Wikipedia is in the top 20; rival sites differ considerably in popularity and so Wikipedia's ranking is much more stable than in the past.

Alexa reach per million measurement for wikipedia.org
Alexa reach per million viewers: (reach figures can be found at the bottom of the Alexa page cited above ). The early part of this list shows only one-week average, but from December 2004 the daily figures are also shown. Another way to look at these figures is in percentage terms. When Wikipedia's reach per million hit 10,000 in June 2005 that meant that 1% of internet users with the Alexa toolbar were visiting Wikipedia each day. In September 2006 this figure reached 50,000 or 5%. The percentage of internet users who visit Wikipedia in a longer period such as a week or a month will be higher than that, as further internet users visit it each day, but it cannot be calculated from the information published by Alexa.

Alexa page views per million measurement for wikipedia.org
Alexa page view statistics for wikipedia.org per million overall page views; the score of 2,000 reached in January 2006 meant in theory that Wikipedia was getting 0.2% of all Internet page views for all sites or one pageview in five hundred; a score of 10,000 would equate to 1% of all internet page views. Since this statistic is only displayed as a graph, rather than a number, you will need to estimate it from the graph displayed via the link given above, and use the date displayed on the graph, which is sometimes not up-to-date. As there is a clear weekly pattern of peaks and troughs, it is best to estimate the average for the last seven days, which will give a more realistic picture of long term trends. This can be done quite accurately using the 7-day graph here.

Alexa country rankings
In April 2006 Alexa introduced rankings on a by-country basis. Wikipedia's rankings are shown in the table below. These are subject to the aforementioned caveats about Alexa rankings and also the additional caveat that not all internet addresses can accurately be sourced to a specific country. Many of the sites ahead of Wikipedia in each country are portals/search engines/ISP sites so its rankings are influenced by the degree of consolidation in those markets in each country.

Note: Access to Wikipedia has been blocked in mainland China most of the time from 19 October 2005 to date. See Blocking of Wikipedia in mainland China.

So how many people visit Wikipedia?
In May 2006 comScore World Metrix, a new global internet tracking system, placed what it calls "Wikipedia Sites" (presumably actually all Wikimedia sites as it makes a point of grouping all sites under common ownership) seventh on its list of "Online Properties Worldwide", with an estimated 131 million unique visitors aged 15+ in March 2006, or 19% of all internet users aged 15+, based on comScore's estimate that there were 694 million of them that month.

The difference from Wikipedia's Alexa ranking is accounted for in part by comscore's grouping of related sites, as Alexa has 2 Microsoft sites and 2 Google sites ahead of Wikipedia, but comScore counts each owner only once. In addition, some sites with much higher daily "Page Views per user", as recorded by Alexa, are ahead of Wikipedia in the Alexa rankings, but not in comScore's rankings, as comScore measures only breadth of use, not intensity of use. By January 2007 Wikipedia's estimated unique user number was 189.0 million, and it was ranked sixth.
