What does the emoji check look for?
Five things: how many emoji there are, the longest run in a row, emoji touching words, emoji used as bullet points, and emoji at the very start of the post.
| Check | Why it matters | Suggestion |
|---|---|---|
| More than three emoji | Each one is read aloud by name | Keep two or three |
| Run of three or more | Repeated names, one after another | One or two is enough |
| Emoji glued to a word | Harder to read, select and search | Add a space |
| Emoji as bullets | Name read before every line | Use line breaks or dashes |
| Emoji first | The first thing heard is a name, not your point | Move it to the end |
None of these are rules. A birthday post with a cake and a balloon at the end is perfectly fine. The check simply makes the cost visible.
How does the screen reader preview work?
It replaces every emoji with its name in square brackets, so you can read the post the way someone listening would hear it.
"Congrats🎉🎉🎉 so proud🥳" becomes "Congrats[party popper][party popper][party popper] so proud[partying face]". Seeing it written out is usually enough to make people trim a run. The names come from a small built-in list of the most common emoji; anything outside it shows as [emoji].
What do the two fix buttons do?
Fix spacing adds a single space between emoji and neighboring words; Move emoji to the end pulls every emoji out of the sentence and puts up to three of them, without duplicates, after the words.
Both run on your text in the browser, and you can undo either with your browser's undo shortcut. Check the result before posting: moving emoji can change meaning if an emoji stood in for a word, which is a habit worth dropping anyway. The emoji readability guide explains why.
Does emoji placement change how a post performs?
There is no public evidence that emoji placement changes reach on X, so write for the reader, not for a ranking guess.
What you can control is how easy the post is to read and to listen to. Words first, a couple of emoji at the end, and spaces in between work for nearly everyone. Draft the final version in the kind post composer to see the exact character count.
