The real cost of inaccessible social content

A five-image carousel takes a team half a day: shoot, edit, caption, schedule, boost. Add up the creative hours and the ad budget behind it, and the two minutes it would have taken to describe those five images is the cheapest line item in the entire campaign. It's also, almost every time, the one that gets cut.

That cut doesn't show up on an invoice. It shows up as a quieter, harder-to-see kind of cost — one most teams never actually measure.

The reach you already lost

Every platform reports impressions as if every viewer receives the same post. They don't. Around 285 million people worldwide are blind or have low vision, and many of them use screen readers that announce a filename instead of a description when alt text is missing. Your impression count includes them. Your actual message never reached them.

The trust that erodes quietly

A sighted follower who dislikes a post scrolls past it once. A screen reader user who hits "image, image, image" across your last ten posts learns something about your brand before they learn anything about your product: that you didn't think about them. That's not a single lost impression. It's a slow, invisible unfollow — the kind that never shows up as a spike in your churn report, just a baseline that's quietly lower than it should be.

It's also the opposite of what most brands say they stand for. A caption about inclusion, sitting above five undescribed photos, reads very differently to someone whose screen reader just skipped all five. The mismatch isn't malicious. It's just what happens when accessibility lives in a values statement instead of a workflow.

The habit that compounds

Skipping alt text once is a rounding error. Skipping it as a house style, post after post, for a year, is a real and growing gap between the audience you think you have and the audience you're actually reaching — and it's invisible precisely because nothing in a standard analytics dashboard flags it. Compare the difference a description makes:

The weak version tells a screen reader user almost nothing they couldn't already guess from the caption. The strong version gives them the actual scene — the same moment everyone else in the audience gets to see.

Why the fix stays cheap

None of this requires a redesign or a new policy document. It requires writing the description at the moment you already have the image open, before it goes out. The cost of that habit is close to nothing. The cost of skipping it, multiplied across a year of posting, is the whole audience and the whole trust it's been quietly taking from you.

Most teams don't skip alt text because they don't care. They skip it because describing ten images means ten separate pauses in a workflow that's already moving fast, right before a deadline. Fix the workflow — write the description in the same place and the same moment you already have the image open — and the habit stops being optional.
