How to make your social media content accessible to all

Accessibility is not a nice-to-have, it is reach

Every time you publish a post that only works if someone can see it clearly, hear it perfectly, or read fast, you quietly exclude part of your audience. Around one in six people worldwide lives with a significant disability, and far more experience situational limits: watching video on mute in a waiting room, squinting at a phone in bright sun, reading in a second language, or scrolling while distracted.

Accessible content is not a separate content type. It is the same post, made easier to consume. The habits below take minutes, they do not dilute your creative work, and they tend to lift performance for everyone because clear content is simply better content.

Start with alt text that describes, not decorates

Alt text is the written description a screen reader announces in place of an image. Most platforms let you add it when you upload, and most people skip it.

Good alt text answers one question: what would someone miss if the image never loaded? Describe the meaningful content, not the file.

• Be specific and concrete. "Bar chart showing newsletter signups rising from 200 in January to 900 in June" beats "chart".
• Lead with what matters. If a person is central, describe who they are and what they are doing before the background.
• Skip "image of" or "photo of". Screen readers already announce that it is an image.
• If the image contains text, repeat that text in the alt description. A quote graphic is invisible to a screen reader otherwise.
• Keep it to a sentence or two. Long alt text is exhausting to listen to.
• If an image is purely decorative, a short neutral description or an empty alt is fine. Do not stuff keywords.

A quick way to build the habit: write the alt text at the same moment you write the caption, not as a final chore before hitting publish. If you draft posts in BrandFleet, keep the description field beside the caption so both get written together.

Caption every video, including the ones people watch on mute

Most short-form video is watched without sound, so captions serve deaf and hard-of-hearing viewers and the large majority who simply never turn audio on. Auto-captions are a starting point, not a finished product.

• Always review auto-generated captions. Names, product terms and accents are where they fail, and a mangled brand name in caption text is worse than no caption.
• Keep caption text inside the safe area. Text buried under a platform's username bar or progress bar is unreadable.
• Use a high-contrast style: solid text on a dark strip or a strong outline. Thin white text over a bright background disappears.
• Avoid word-by-word "karaoke" captions that flash too fast to read. Two or three lines that hold for a beat are kinder.
• Upload a caption file where the platform supports it. Burned-in captions cannot be resized or translated by the viewer.

For audio-first content like podcast clips, publish a transcript or a written summary alongside the clip. That single habit also gives search engines and AI assistants something to index.

Write so the content can be heard as easily as read

Screen readers read characters literally, and that changes how you should write.

• Put hashtags at the end of the caption, and capitalise each word in them. #SocialMediaTips is read as three words; #socialmediatips is read as a jumble.
• Use hashtags sparingly inside sentences. A caption interrupted by tags is hard to follow aloud.
• Go easy on emoji. Each one is read aloud by its full description, so a row of twelve sparkles becomes a long, strange sentence. One or two, placed at the end of a thought, is plenty.
• Avoid stylised Unicode fonts, the fancy bold or script characters people paste into bios. Screen readers either skip them or read them character by character. They are one of the single most exclusionary habits on social media.
• Do not rely on ALL CAPS for emphasis over long stretches. Some screen readers spell out capitalised words, and capitals are harder for many people to read.
• Write plainly. Short sentences, common words, one idea per paragraph. Explain jargon the first time you use it.

Design for contrast, size and calm

Visual choices decide whether your post is legible on a cracked phone screen in daylight.

• Aim for strong contrast between text and background. If you squint and the text starts to dissolve, the contrast is too low. Pale grey on white and thin pastel text over photos are the usual culprits.
• Never use colour alone to carry meaning. If red means "avoid" and green means "do", add a label or icon so the distinction survives colour blindness.
• Set text large enough to read at thumbnail size. If it is illegible in the feed preview, it is illegible.
• Give text room to breathe. Generous spacing and short lines beat a dense block of copy over a busy photo.
• Avoid rapid flashing, strobing effects and heavy motion. These can trigger migraines and seizures, and platforms increasingly deprioritise them anyway.
• Warn before intense content. A brief note at the top of a caption lets people opt out.

Bake these rules into your brand kit rather than deciding case by case. Fixed colour pairings, a minimum text size and an approved caption style mean accessibility survives busy weeks and new team members.

Make links and calls to action clear

• Write descriptive link text. "Read the pricing guide" tells someone what happens next; "click here" tells them nothing when read out of context.
• Do not paste raw tracking URLs into captions. A long string of parameters is read aloud in full.
• Keep one clear action per post. Multiple competing asks are hard for anyone to parse.

Build a short pre-publish check

Accessibility fails when it depends on remembering. Turn it into a checklist your whole team runs before anything goes out.

• Does every image have meaningful alt text?
• Are captions on the video, reviewed for accuracy, and inside the safe area?
• Are hashtags at the end, capitalised per word?
• Is emoji use restrained and placed at the end?
• Are there any stylised Unicode fonts to remove?
• Does text contrast hold up when you view the post at phone size?
• Does any meaning depend on colour alone?
• Is the call to action written as descriptive text?

Eight questions, under two minutes. Run it as the last step of your approval flow so nothing ships without it.

Test with real conditions

You do not need specialist software to catch most problems.

• Turn on your phone's built-in screen reader and listen to one of your own posts. It is the fastest way to hear where captions become nonsense.
• View your drafts at actual size on a phone, outdoors if possible, rather than on a large monitor.
• Mute a video and watch it end to end. If you cannot follow the point, your captions are not doing their job.
• Ask someone outside your team to describe what your post is asking them to do.

Make it a default, not a project

The brands that get this right do not run an accessibility campaign. They change their templates once, add a few questions to their checklist, and let the habit compound. Six months later every post is easier to read, their video performs better on mute, and nobody is doing extra work.

Set your defaults now: an alt text field that is never left empty, a caption style that meets contrast, hashtags at the end, and plain language throughout. Then let the system carry it.

If you want that consistency without policing it manually, start with BrandFleet. Plan, write and schedule everything in one place, keep your brand kit and caption standards attached to every post, and give your whole audience a fair chance to read what you publish.
