Stock footage platforms have an internal search engine that allows users to search the topics that interest them.
Just as with search engines such as Google, those of sales platforms also work through the use of keywords. Consequently, when a clip is uploaded to the platform, it must be assigned one or more keywords using tags, so that the clip can be found.
If the keyword is missing or incorrect, the clip becomes almost untraceable, with obvious consequences.
However, attributing a tag is much less trivial than you might think: the keyword must not only describe what is shown in the scene, but also has the function of expressing all the concepts that the clip can represent.
Generally, in fact, those performing a search on platforms often use keywords related to concepts rather than descriptions: if only descriptive tags have been attributed to a clip, the risk is that it will not be found and the potential client will be lost.
