Why you really ought to add human powered captions to your YouTube Channel.

When implemented correctly YouTube captions are read and indexed by both YouTube and Google just like text based web pages. Captions are treated as a full, accurate textual representation of your video.

It is important to note that YouTube’s automatic captions are NOT indexed by Google or YouTube due to their inaccuracy.

High quality professional captions are the quickest and best way to take instant advantage of SEO benefits and rapidly  gain more viewers, subscribers and generate interest in your channel.

For too long hearing loss has been ignored, overlooked and disregarded despite the millions who live with its consequences.

There are more than 11 million people in the UK with some form of hearing loss, 1 in 6 of the population.  By 2031 this figure is expected to rise to 14.1 million people or nearly 20% of the population of the UK.

According to the World Health Organization (WHO), 28 million of the 190 million Brazilians have hearing problems, a number corresponding to 14% of the Brazilian population.

In the United States About 20% of Americans, 48 million people, report some degree of hearing loss .

By the age of 65, one out of three people has a hearing loss.

60% of the people with hearing loss are either in the work force or in educational settings.

Studies indicate that these numbers will only increase.

By not captioning your videos correctly you are effectively excluding many people from your channel and you are losing out on thousands of viewers, potential customers and a huge business opportunity.
