Can someone tell me if keywords are used outside of photoshop?

One way to benefit is to add keywords before uploading images to (some) stock sites. Imagine stock sites without keywords, probably it will be different experience. Not sure if Google is using embedded keywords because many people will immediately start abusing keywords as they did in the past with site and page keywords.

IPTC-standard keywords, which Adobe photo applications use, are used widely, to help find photos in photojournalism, stock photography, science, and other fields. Keywords you enter in Photoshop, Adobe Bridge, and Lightroom can be read by other non-Adobe applications, can be found with the desktop search in macOS, iOS, and Windows devices, and on photo websites like Flickr that can show and search on IPTC metadata.

If you want to know more about how keywords and other metadata are used in the world, not just in Photoshop, you can read the IPTC Metadata User Guide .

The use is more limited in video, partly because the standard is not as widely implemented in video applications.

Hi @sjr23464752 I'm not exactly clear on what your question is. Are you asking if keywords embedded into the metadata of an image using Photoshop can then be read in another program? The short answer is yes.
