The keyword suggestions features within Hike are only supported for English-speaking countries at the moment.
Although they will work in other languages (such as Spanish, French, German and more) but we cannot guarantee the quality as we have only perfected Hike for English.
The local SEO citation audit provide suggestions only in English. If you want to use these features then your website needs to be in English.
However, every other feature is language-agnostic, such keyword tracking (we can track keywords in almost every single Google locale), backlinks and competitor data.
