The main challenge facing migration scholars in designing effective advertisements has been to identify and accurately target migrants on Facebook. Researchers have used proxies, such as users&rsquo; previous residence abroad, language(s) or interests, to infer their migration status. Despite some progress, there remains a need to better document and reflect critically on the accuracy of targeting migrants using such proxies. Contrary to studies which relied on users&rsquo; previous residence abroad, this study used migrants&rsquo; language (Polish) to target and recruit survey participants from among Polish migrants in Norway, Sweden and the UK. Focusing on a single migrant group across three countries, the goal of this article is to assess the accuracy of a targeting strategy which relied primarily on users&rsquo; command of a language as an indicator of their migration background. Comparing the results against official migration statistics and the results reported in similar studies, the article provides a compelling case for researchers to prioritise users&rsquo; language, rather than previous residence abroad, as the proxy for migration background for migrants whose language, such as Polish, is confined to the borders of a single nation state.</p>10aFacebook advertisements10alanguage targeting10amigration research10aparticipant recruitment online10aPolish migrants1 aRyndyk, Oleksandr  uhttps://ceemr.uw.edu.pl/content/language-based-recruitment-migrants-online-surveys-facebook-advertisements-comparative
