When optimizing my website for local SEO (targeting my city of residence) I am keen to geotag the important images (photo's) that are displayed on the website and to create an image sitemap. This to improve the relation between the website and the city I am targeting.
Now there are two factors that I can modify:
- The image location in the image sitemap XML field
- EXIF data associated to the image
According to Google the XML field should look as follows:
<image:geo_location>Limerick, Ireland</image:geo_location>
This suggest the level of detail goes up to the city, rather then the full address. In my case this would result in >Amsterdam, The Netherlands< for -all- images. Wouldn't it better to add one level (Address) in order to differentiate the one image from the other when it comes to the geo_location information?
Adding the address would be nice since the EXIF data generally contains a latitude a longitude field that pinpoints the exact location (or address) where the photo was taken.
To me the combination of these fields provide Google with the best possible information about the geo_location. However, I am wondering if it matters what I think.
So my question is: Who knows the best practice when it comes to image sitemaps and EXIF data combinations with regards to images on a website?
