Free translation of the spanish article from Hugo Avila (september 2nd 2017) : Google Tag Manager en Gantry5
Do you use the Google tracking tools on your websites? If you do not do so now, you are missing out on valuable statistics on the use and behavior of your page visitors. Needless to say the benefits you can get when analyzing the data and take measures to improve conversions, among other advantages.
After the site En Toutes Lettres, the Gantry 5 demonstration site, Hydrogen template, dedicated mainly to the particles developed by En Toutes Lettres, but also to variations around the Hydrogen template, made new skin.
For reasons of clarity and maintenance, the site is now managed only with the Hydrogen template, so the demonstrations of the other templates have been removed.
CAUTION: if you use the template Kunena Simone of Jomforest, you must install the 2 patches successive Kunena 5.0.9 and 5.0.10. !
Knowing that kunena is now in 5.0.11 !!
