Video titles and descriptions benefit from related-term research the same way written content does, giving platforms and search engines a fuller sense of what the video actually covers.
Include Related Terms in the Description, Not Just the Title
A thorough video description has room to naturally include related vocabulary that wouldn't fit in a short title alone.
Reflect Related Subtopics in Chapter Titles
Breaking a video into chapters around related subtopics mirrors how a written piece would use subheadings to signal broader coverage.
Use Related Terms in Spoken Content Where Natural
Since transcripts and captions are often indexed, naturally including related terminology in what's actually said in the video reinforces relevance beyond the metadata alone.
Next step: Use the LSI Tool to find related terms worth including across a video's title, description, and chapters.
