Images aren’t magic on X. Proof is.
An image won’t rescue a weak post on X, but a screenshot that proves your claim can carry a good one.
Somewhere along the way, “always add an image” became social media law. On X, the data is a lot less dramatic than the law.
Buffer’s 2026 content-format report, built on more than 45 million posts, looked at median engagement rates by format. On X, text posts came out on top at 3.56 percent, images were close behind at 3.40 percent and videos came third at 2.96 percent. Those are medians, not viral outliers, and Buffer itself stresses that every audience is different. The takeaway isn’t “never use images.” It’s that an image doesn’t do the work for you.
So use visuals the way a lawyer uses evidence. Don’t write “onboarding is way faster now”; post the before and after screen recording. Don’t write “revenue is growing”; post the cropped revenue chart, with customer names and emails hidden. A screenshot should prove the sentence above it, not decorate it.
The example
- Instead of
- “Onboarding is so much faster now! [stock photo of a rocket]”
- Try
- “We cut onboarding from 9 steps to 3. Before and after screen recordings below, 22 seconds each.”
Before you flush
Find one claim in a recent post or draft and back it with proof: a cropped screenshot, a before/after or a 20-second screen recording.
