Need to promote mobile app startup in Europe. Please suggest some free/paid marketing channels

[Jessica]

Hola! I’m here for your advice. I’m working for a company (a startup with a mobile app that helps travelers find companeros for long-term apartment rentals in Spain). We want to expand our online marketing in Europe and the UK, and even have budgets for growth. However, I don’t know what channels I should use. I mean, I know Facebook and Instagram ads, but what other digital channels should I take into account? I’ve also posted in groups on Facebook. Please suggest some good free and paid options. If ads, please advise smth except for Facebook ads. Thank you very much! – by hq overview Rivera_Alex – –
