X will now match your ad spend if you advertise a Shopify product. In a new partnership with Shopify that will only be valid through December 1, 2024, X announced that it will match up to $100k in ad spend for up to 30 days.
In other words, for every $100 you spend advertising your Shopify product on X, X will add $100 in ad credits to your account. This currently applies to Shopify sellers in the US or Canada.
