About

Ad Spec Sheet is run by Thomas Leeming, an independent Meta and Google Ads specialist who has managed more than $50M in ad spend.

The site exists because ad specs change constantly and most reference pages are slow, padded and undated. Here every spec links to the platform's own documentation with a "last checked" date, and anything we cannot verify is marked or left out.
