”Whereas the mere accessibility of [your] website in the Union, of an email address or of other contact details, or the use of a language generally used in the third country where the controller is established, is insufficient to ascertain such intention, factors such as the use of a language or a currency generally used in one or more Member States with the possibility of ordering goods and services in that other language, or the mentioning of customers or users who are in the Union, may make it apparent that [you] envisages offering goods or services to data subjects in the Union.”

Do not translate your site to EU-only languages (Italian, German, etc.), use an EU based domain extension, or create content or services that would be especially appealing to EU users, and GDPR will not apply to you.
