How do I improve accuracy of visitors’ Country detection, and enable Cities and Regions tracking?

By default Matomo (Piwik) uses the browser language to determine location. To improve accuracy of country detection (and enable Region and City tracking), go to Matomo > Administration > Geo Location. Then, you can select the appropriate solution for your install. These include the PHP DB-IP (default), the PHP GeoIP library from Maxmind (it can provide better accuracy than DB-IP) or a server side solutions such as GeoIP Apache or GeoIP PECL modules (all solutions will also require a geolocation database such as the Lite databases from DB-IP).
