Geotagging may be enough for your own catalog if your software can search location metadata well. But location keywords can still be useful, especially when you export or share images to other sites or apps.

The main reason: not every service supports geolocation-based searching, while many do support keyword searches. If someone searches for a city or place name as a keyword, your images may be easier to find if that location is also stored in keywords.

So geocoding is great for organizing and mapping, but keywords can improve portability and discoverability outside Lightroom. A practical approach is to rely on geotagging for precise location data and keep location keywords when you want broader compatibility or searchable place names.
