With subtitles, video search becomes more meaningful. The best example of this is with YouTube and Google. Google owns YouTube and will index all of the subtitles that have been added to YouTube videos. It’s a great way to add meta-data to your video, your content and your website.
Subtitles Video Search
Subtitles enable much more than video search and SEO, however. It is now possible to link to a specific moment in the video based on what is being said. Even videos with no speech at all can use a subtitle file to add information to the video element. And all this information gets picked up by search engines which can point people to your web content.
