How to spot posts going viral early on X

The fastest way to spot an X post going viral is to compare it with what that account normally gets, within the first few hours. A post doing five or ten times its account's usual numbers is breaking out, even if the raw count still looks small.

The signals that matter

• Speed: how many interactions a post has in its first hour or two, compared with that account's usual posts at the same age.
• Shares relative to likes: when people pass a post on, it's traveling beyond the account's own followers.
• Comment spikes: a sudden flood of comments often means controversy or breaking news.
• Pickup elsewhere: the same story starting to appear on other accounts or platforms.

Doing it by hand on X

1. Build an X List of the accounts on your beat. Lists can be private.
2. Get a feel for each account's usual reposts, replies and likes. X also shows a view count on posts.
3. Watch for posts with unusually fast reposts and quote posts, which signal a post spreading.

Where the manual method breaks down

A List shows posts in order, not by how unusual they are, so a breakout from a small account scrolls past between routine posts from big ones.

Doing it with SocialWire

Add the X accounts you follow to a SocialWire list, alongside accounts from other platforms if you like. SocialWire scans them on your schedule and sorts every post by ×normal, so the breakouts are at the top.
