Key Takeaways

Transcription converts audio into standalone text for reading, documentation, and repurposing, while captions provide a visual description and display synchronized text on videos to support accessibility and the viewing experience.
Transcripts provide searchable, indexable text that helps videos and audio content rank higher, increases engagement, and supports content repurposing into blogs, articles, and documentation.
Captions improve watch time, reduce bounce rates, and make content accessible to hearing-impaired and global audiences, especially on social and video platforms.
Combining transcripts (for search visibility and reuse) with captions (for accessibility and engagement) creates stronger overall SEO, usability, and audience reach.
The choice depends on the content type and goals. Use transcription for podcasts, documentation, research, and SEO-focused content. Use captioning for videos, social media, compliance, and audience engagement. For video-based, global, or educational content, both are ideal.
