TL;DR sections have been around for a long while, but since GEO became a thing, they’re on every article.
The logic is to give AI crawlers a breakdown of key information at the top so they will retrieve and cite your page as the source of that information.
Similarweb published some research last week testing this.
But there's still no direct evidence that adding a section called "TL;DR" increases AI citations.
So instead, I wanted to look at where this came from and what data does support everything a good TL;DR does.
