The internet is allowing companies to finally be accessible to all audiences - take advantage of this and become a brand that people want to affiliate themselves with. This means adding subtitles and closed captions for people who are hard of hearing, as well as ensuring the audio is loud enough for everyone to hear clearly. Speaking slowly and clearly will also help, as it's easier to follow spoken words in video than in text-based media. Also, those who want to read would appreciate a transcript of your video, so this is something else to consider. Finally, ensure that you have diverse representation in your videos - this will help make everyone feel seen and respected.
