Social strategy
Make social content easier to see, hear and understand
A beautifully designed event announcement can still hide the date in tiny lettering. A useful video can lose its meaning when the sound is off or its automatic captions mishear a name. Accessibility is part of whether a post communicates, so it belongs in the brief and review process from the beginning.
Keep the essential message available as text
Identify the information someone must receive: the event date, the product difference, the instruction or the result. Put essential details in the caption or another appropriate text field as well as the visual. If a chart carries the argument, explain the important finding and provide a way to read the underlying values when they are needed.
This also improves the working brief. A designer who knows the date and booking deadline are essential can build a clear hierarchy instead of shrinking them into a footer. Do not assume that text drawn inside a JPEG will be available to every assistive tool in the same way as platform text. Check the actual destination rather than relying on the design file alone.
Write image descriptions for the reader
W3C’s image guidance distinguishes purpose and context: the useful alternative for an informative image conveys its meaning. For a post about packaging, describe the relevant feature, such as a refill pouch beside a reusable bottle. You do not need to list every background object when those details add nothing to the point of the post.
Avoid opening every description with a promotional claim or a string of search terms. If the image contains essential words, make those words available too. Use the platform’s supported alt text feature where it exists and verify it after publication. Automated descriptions can be a starting point, but they may miss a product detail or interpret a demonstration incorrectly.
Review captions as carefully as the spoken copy
Captions should communicate speech and relevant non-speech audio, not simply approximate the conversation. W3C’s guidance explains why accurate, synchronized captions matter. Check names, technical terms, numbers and the timing of each segment. A wrong price or a missing negative can reverse the meaning, even when the rest of the transcription looks plausible.
Preview on a phone to see whether captions cover a product feature or disappear behind the platform interface. If the video communicates essential information through visuals alone, consider how to describe that information in narration or another accessible equivalent. A silent demonstration of three controls may need spoken identification, not only background music and a caption saying Watch this.
Give the design enough contrast and space
As a useful design benchmark, WCAG’s minimum text contrast is 4.5:1 for ordinary text and 3:1 for qualifying large text. Contrast is one part of accessibility, not a certificate that the entire post is accessible. Thin type, compression and busy backgrounds can still make a technically acceptable color pair difficult to read at feed size.
Test the final export, not only the editor view. Use a solid panel behind important words when the photograph changes too much for reliable contrast. Pair color-coded information with text or another clear cue, so a red or green status is not the only explanation. Keep motion purposeful and avoid rapid flashing or unnecessary visual movement around essential instructions.
Make access part of the handoff
Give each asset a small accessibility note alongside the approved caption: image description, caption file or transcript, and any important visual explanation. Identify who checks those elements in the destination tool. Exporting a flat image or moving a file between applications does not guarantee that accessibility information travels with it.
Invite feedback in a way the team can act on, and record recurring problems in the template or briefing guide. If customers cannot read a recurring disclaimer, fix the template instead of enlarging it manually every week. A manageable process, repeated consistently, is more useful than an accessibility checklist that appears only when a campaign is already ready to publish.
