Country Level Weighting
Market share number are now weighted by country
In the past, we reported only on our raw numbers. As of August 1st, we have implemented retroactive country-level weighting in our reports. This means that we adjust our reports proportionally based on how much traffic we record from a country vs. how many internet users that country has. For example, although we have significant data from China, it is relatively small compared to the number of internet users in China. Therefore, we now weight Chinese traffic proportionally higher in our global reports. This change produces a much more accurate view of worldwide usage share statistics.
After consulting with many of the organizations we report data on, we decided to use C.I.A. data as the source of the number of internet users per country.
In addition to providing better share numbers, the reason we made this change was due to growing traffic imbalances in certain countries. Some countries were growing traffic at a much higher pace than the rest of the world and it was creating unacceptable variances in the share numbers. The reason we delayed June numbers was due to these imbalances. From now on, a single high growth country will not be able to affect the global share numbers.
This change has produced some significant changes in usage share for various technologies. The primary ones are:
Baidu - Baidu goes to 9% of global search engine usage. Baidu is on a major growth curve, which is affecting the relative share of all other search engines.
Google - Because of Baidu's growth, Google's global share is actually going down. This is almost completely due to Baidu and does not reflect the rest of the world.
Apple - Since Mac share in the U.S. in significantly higher than the rest of the world, Mac and Safari share drop in the global reports.
Opera - Opera goes up to 2% in global reports. This reflects the significant share they have in Eastern Europe and Asia.
