In episode 193 of Semantic Mastery's weekly Hump Day Hangouts, one participant asked about the team's thoughts on the benefits of adding exif data to images for GMB posts and featured images on blogs.
The exact question was:
I recently got HoudahGeo which allows a LOT of exif data to be added to photos (long, lat, title, description, keywords, NAP, url to money site). Testing exif pics on GMB posts and as featured images on blogs. Any insights you guys have on to a bump this will or will not provide? Is it worth it?
