As the digital world continues to expand at a rapid rate, so does the prevalence of online video content across many industries and sectors of society.

In recent years, social media has evolved into a form of digital beast that has yet to be tamed. Especially since the turn of the century, advancements in wireless internet technology and digital media have led to the emergence of a whole host of new platforms.

This has resulted in online video content becoming a powerful marketing tool that has the ability to drive business growth and success in what is often a highly competitive marketplace.

To get the edge on the rest, marketers are starting to use subtitles more often than before – but what are subtitles and why do they matter? We will cover this topic in more detail below.

Key Takeaways:

Roughly one in two US viewers now watches with subtitles on, so publishing video without them means ignoring how people actually watch.
Open subtitles are burned into the frame while closed ones toggle on demand – the right pick depends on where your video will play.
Beyond translation, subtitles help viewers follow dense dialogue, stay focused for longer, and build stronger reading skills.
Search engines rank text, not audio, which makes caption files one of the few direct SEO wins available to video.
Translated subtitles remain one of the fastest and most affordable ways to reach audiences in other languages.

What are Subtitles?

As a general definition, subtitles consist of text displayed at the bottom of a cinema or television screen to provide additional or interpretative information.

Of course, this description can now be extended to online videos, with subtitling being very common in visual media accessed over the internet.

Video subtitles do not typically include sound effects and they provide an alternative for the dialogue of video footage, such as the spoken words of characters and narrators.

Subtitles can be broadly categorized into two types: open and closed. The former are embedded in the video itself and cannot be switched off, while the latter can be turned on and off by the viewer.

Subtitles vs Captions

When referring to text that appears on a video screen, it is common to hear the terms of subtitles and captions being used interchangeably.

However, these words are not synonymous with each other. They each have distinctive features that allow us to distinguish between them in terms of definition and purpose.

Essentially, captions are designed for viewers who are unable to hear the spoken word, or audio, of a video, whereas subtitles are for those who can hear, but do not understand what is being said, such as the language.

Meanwhile, a specific type of caption, known as closed captioning, is an American term for closed subtitles and is specifically intended for deaf or hard-of-hearing individuals.

Why are Subtitles Important?

The importance of subtitling cannot be overstated in the contemporary world, with an increasingly globalized environment meaning that a greater emphasis is placed on accessibility.

More people from different countries with their own cultural backgrounds are viewing similar content. Therefore, subtitles play a crucial role in terms of communication, by informing those who may not understand what is being said.

In the section below, we will be taking a look at some of the key reasons why they can be a vital tool going forward.

● Clarity

The addition of subtitles to a video adds clarity to the content, especially with regards to technical language, industry jargon or terminology that is hard for viewers to decipher. It can also help the audience better retain information gleaned from the video, as it provides not only audio but also a visual stimulus.

● Engagement

Including caption text or subtitles is a good way to improve and extend the amount of time an individual watches a piece of video content. It is possible to maintain concentration for longer periods if there is a text-based aid on screen at the same time. Enhancing the level of general engagement also helps those viewers with attention disorders or autism.

● Literacy

Subtitles can also play a role in improving the overall literacy and comprehension of those who view the content. So long as the subtitle text itself is grammatically correct, it can encourage better literacy, through boosting reading speed and fluency, vocabulary acquisition, word knowledge and recognition, as well as listening comprehension.

● Inclusivity

Making videos as accessible as possible is a very worthwhile endeavor, which is why adding subtitles is an excellent starting point. It can act as an extremely useful resource tool for non-native speakers, while it allows the author to share their content across multiple regions around the world. Subtitle translation is certainly the future of online content because it inevitably widens its potential reach.

● SEO

Subtitling helps to strengthen the position of a video in search engine rankings. Google cannot watch your video or listen to its audio, but it can read caption files and transcripts. Scoring high in search results can be the difference between a successful and a failed video, as it ensures greater visibility. This can be crucial in what is a highly competitive and ever-expanding online marketplace.

Why do People Use Subtitles More Than Ever?

The biggest shift since streaming took over is that subtitles stopped being a niche setting and turned into a default habit. In Preply’s 2023 survey of more than 1,500 Americans, 51% said they watch content with subtitles most of the time. Another 61% said background music makes dialogue harder to hear than it used to be.

The habit also skews young. According to YouGov’s 2023 data, 63% of US adults under 30 prefer subtitles on even when they know the language. That preference took shape on social feeds, where video autoplays silently and text carries the message. For brands, that changes the math: subtitles now sit inside the wider media localization toolkit rather than on the list of extras. A clip that ships without them gives up a large share of its audience before the first second plays.

FAQ

Why does Gen Z use subtitles so much?

Younger viewers grew up on platforms that add captions automatically, so reading along feels natural rather than optional. Preply’s 2022 survey found that 74% of Gen Z have watched shows, movies, or online videos in public, a setting where subtitles beat sound.

What are the benefits of embedded subtitles in videos?

Embedded, or open, subtitles are part of the picture, so they display identically on every device and platform. Nobody hunts for a CC button, and nothing gets lost when a file is re-uploaded, shared, or shown on a screen with no caption support. The trade-off is that they lock the video to one language, so they suit single-market campaigns better than global ones.

Do subtitles help with language learning?

They do – pairing spoken audio with written text helps learners connect sound to spelling and see how real conversation flows. It works in both directions, too. Subtitles in the language you are studying stretch you further, and captions in your own language keep the plot clear as your ear adjusts.

Can one video carry subtitles in several languages?

Yes – multilingual subtitles ship as closed tracks, where each language sits in its own file and the player shows whichever one the viewer picks. Our guide to video translation from A to Z covers how those tracks are created, timed, and checked before release.
