@harrischh If it's hard to track, then your not getting enough ;-) anyway, if your traffic increases independent of ad traffic and paid referrals, that's when your getting WOM.
I think the number one sign of Product Market Fit is when customers are consistently coming back and using your product. If they keep coming back, it means they see real value in what you’re offering.
I believe a clear sign of Product Market Fit is when you start getting unsolicited positive feedback from users. When people reach out to tell you how much they love your product, you know you’re on the right track.
I think the biggest sign is when you start seeing organic growth in your user base. If people are finding and using your product without heavy marketing, it’s a sign that the product is meeting a genuine need.
