How it works
- The snippet is a plain link wrapped in a
div. With JavaScript,/embed/v1.jsswaps it for a small iframe card; without JavaScript, readers still get the link. - Cards set no cookies, load no third-party scripts and collect no personal data. We count anonymous card views by page and referring site only.
- Figures are copied from the evaluator, are modeled, not guaranteed, and are labelled as such on the card.
- Prefer a bare iframe? Use
<iframe src="https://diditwork.org/embed/SLUG" width="100%" height="230" style="border:0;max-width:440px" title="Evidence card"></iframe>.
Citing a page
Suggested form: Did it work?, "Charity name: evidence and published figures," https://diditwork.org/charities/SLUG. Please cite the evaluator (GiveWell or the Happier Lives Institute) alongside us.
