Why Accessibility Matters on Social Media
Accessibility is not a niche concern. Globally, over one billion people live with some form of disability, and many more experience temporary or situational accessibility needs. Someone watching your video in a noisy environment needs captions just as much as a person who is Deaf. Someone browsing social media on a sunny day needs good color contrast just as much as a person with low vision. When you design your social media content with accessibility in mind, you serve your entire audience better, not just the subset that uses assistive technology.
Beyond the moral imperative, accessibility is good business. Accessible content reaches more people, generates more engagement, and signals to your audience that your brand values inclusion. Many organizations and individuals actively choose to support brands that demonstrate genuine commitment to accessibility.
Image Accessibility
Writing Effective Alt Text
Alt text (alternative text) is a written description of an image that is read aloud by screen readers and displayed when images fail to load. Every image you post on social media should have meaningful alt text. Most major platforms, including Instagram, Facebook, X (formerly Twitter), and LinkedIn, allow you to add custom alt text to images.
Good alt text describes the content and function of the image. Instead of writing “photo” or “image of product,” describe what is actually shown: “A person holding a latte in a red mug at a window seat in a coffee shop, smiling as they look at their phone.” Include relevant details but keep descriptions concise, typically one to two sentences. If the image contains text, include that text in the alt description.
Text in Images
Many social media posts use text overlaid on images to convey key messages. This text is invisible to screen readers unless it is also included in the alt text or caption. Whenever you use text in images, repeat that text in the caption or post body so everyone can access it. Consider whether the information could be conveyed as a text post instead, making it universally accessible without any extra effort.
Color and Contrast in Graphics
Ensure that any text overlaid on images or graphics has sufficient color contrast against the background. The Web Content Accessibility Guidelines (WCAG) recommend a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text. Use online contrast checkers to verify your color combinations. Avoid conveying information solely through color, since people with color vision deficiency may miss the meaning. Use labels, patterns, or shapes in addition to color when differentiating elements in charts, infographics, or other visual content.
Video Accessibility
Captions and Subtitles
Every video you post on social media should have captions. This includes Reels, TikToks, Stories, YouTube videos, and any other video format. Captions make your content accessible to people who are Deaf or hard of hearing, but they also benefit the large number of people who watch social media videos without sound, whether by choice or because of their environment.
Use accurate captions that match the spoken words. Auto-generated captions are a starting point, but they frequently contain errors. Always review and correct auto-captions before publishing. Include descriptions of significant non-speech audio, like music or sound effects, when they are important to understanding the content.
Audio Descriptions
For video content where important visual information is not described in the narration or dialogue, consider adding audio descriptions. These are narrated descriptions of visual elements like on-screen text, actions, settings, and expressions that would be missed by someone who cannot see the video. While full audio descriptions are not always practical for every social media video, be mindful of how much of your video’s meaning relies on visual elements that are not described verbally.
Flashing and Motion
Avoid flashing content that could trigger seizures in people with photosensitive epilepsy. Keep flashing effects below three flashes per second. Also be mindful of rapid motion, auto-playing animations, and other effects that can be disorienting for some viewers. When using motion-heavy content, consider providing a content warning.
Text and Language Accessibility
Plain Language
Write in clear, straightforward language that is easy to understand. Avoid jargon, overly complex sentences, and industry-specific terminology without explanation. Plain language benefits everyone, not just people with cognitive disabilities. It improves comprehension for non-native speakers, people reading quickly on mobile devices, and anyone who encounters your content for the first time. Short sentences, common words, and clear structure make your content more accessible and more engaging.
Hashtag Formatting
When using multi-word hashtags, capitalize the first letter of each word, known as CamelCase or PascalCase. For example, use #SocialMediaMarketing instead of #socialmediamarketing. This formatting allows screen readers to pronounce each word separately, making hashtags intelligible for screen reader users. It also improves readability for all users, so this is a simple change with universal benefits.
Emoji Usage
Emojis are read aloud by screen readers using their official descriptions. A string of ten emojis can result in a long, disruptive stream of descriptions that obscures the actual message. Use emojis sparingly and purposefully. Place them at the end of text rather than between words, and avoid using emojis as replacements for words in a sentence. Do not use emojis to create visual art or patterns in your posts, as these are completely unintelligible to screen reader users.
Link Accessibility
When sharing links, use descriptive link text that tells people where the link goes. “Read our accessibility guide” is far more useful than “Click here” or a raw URL. On platforms that allow link text formatting, always use descriptive labels. On platforms that require raw URLs, add context in the surrounding text about what the link leads to.
Platform-Specific Accessibility Features
Instagram supports custom alt text for feed posts. Access it during the posting process under Advanced Settings. Use it for every image post. For Stories and Reels, add on-screen captions and ensure text has sufficient contrast against backgrounds.
Facebook generates automatic alt text for images, but you should always add custom alt text that is more descriptive and accurate. Facebook also supports automatic captions for videos, which you should review and edit for accuracy.
X (Formerly Twitter)
X supports image descriptions that function as alt text. Enable the image description feature in your accessibility settings if it is not already active. Use it for every image you post.
LinkedIn supports alt text for images in posts and articles. Add descriptive alt text to every image. For video posts, upload captioned versions or use LinkedIn’s auto-captioning with corrections.
TikTok
TikTok offers auto-captions and text overlay features. Always add captions to your videos. Use the text-to-speech feature judiciously, and ensure any on-screen text stays visible long enough for all viewers to read it.
Creating an Accessibility Checklist
Develop a pre-publishing checklist for your social media team. Before every post goes live, verify the following: images have descriptive alt text, videos have accurate captions, text in images is repeated in the caption, color contrast meets minimum standards, hashtags use CamelCase, emojis are used sparingly and appropriately, links have descriptive context, and language is clear and jargon-free. Building these checks into your workflow ensures consistency and makes accessibility a habit rather than an afterthought.
Ongoing Learning and Improvement
Accessibility is an ongoing practice, not a one-time project. Follow disability advocates and accessibility experts on social media to stay current on best practices and evolving standards. Listen to feedback from your audience about accessibility issues and act on it promptly. Test your own content with screen readers and other assistive technology to understand the experience firsthand. Each improvement you make expands your reach and demonstrates genuine inclusion.
