Where do users come from?
Traffic estimate last month: the top channel is direct at 64.35%, followed by organic search at about 26.7%, social at about 5.3% (Reddit, X, YouTube), and paid at 0.35%. Apart from the brand keyword 'yadaphone', the search terms are all country codes and calling needs, such as 'prefisso', '212 country code', 'paginas para llamar con link', and 'free calling online', 668 keywords in all, which suggests it feeds on multilingual search through long-tail pages by area code and country. In 2025-03 the founder posted three times on Hacker News, each getting only 1 to 2 points; before 2025-11 there was a Starter Story video, 'I rebuilt a $1B app and now make $14K/month', that an HN commenter took to be this founder's video. Existing users come back through prepaid balances and direct visits.
