When you load up a video on the internet you have to ask yourself, what do search engines know about this video?
The name, definitely.
The content? Maybe… but only by any description or tags that you add to each video.
Search engines can’t watch a video to interpret the message in a video, so they won’t understand the content of the videos without a transcription or captions.
But once you load up captions on a video the search engines have much more good content to search on and find. When captions are provided the search engines can rely on the captioned text and metadata to identify the keywords and the intent of the message in the videos.
You might be surprised how captions can help your rankings in search engines.
Give it a go, and see how captions can help improve the SEO of your website and videos.
