• You can test the French market by having an excerpt translated (for example, the first chapter) and publishing it on Wattpad, Medium, or on your blog, website, or newsletter. You can then analyze the readership data, reactions, and reader feedback.
• Another option is to create a landing page on your website announcing your book's arrival in French, with or without a mockup cover (labeled "subject to change"), and a "Notify me upon release" button to measure reader interest and collect email addresses for your newsletter.
