+I recently spent some time writing my own script based on exiftool to help me with mass-geotagging of 
+old photos, taken 10-15 years ago when geotagging was not that common
+(or trivially, the GPS sensor was not yet available in all smartphones!).
+
+After creating and validating the script, I found a much easier and ready solution was already there: [DigiKam](https://www.digikam.org/).
+A brief step-by-step procedure to mass geo-tag photos with DigiKam:
+
+1. Import all your photos (a.k.a. "albums" for DigiKam) in the application. This will take a while if you have many files.
+2. Navigate your album by folder names (that's where I can find information on the location where photos were taken);
+3. Select all photos (`CTRL+A`);
+4. Bring up the "Geolocation Editor" (`CTRL+SHIFT+G`);
+5. Select all photo thumbnails;
+6. Use the "Search" panel to find the location on the map where you think all photos were (roughly) taken;
+7. Right-Click on the location result and select "Move selected images to this position";
+
+And voilà.
+However this only works fine if all the photos you want to geotag live in the same folder.
+If they are nested within multiple folders, you may want to look at [my mass-geotagging exiftool script](https://gist.github.com/f18m/5b54dd6f2838920762dc987671ac935e).
