For me, the most common mistakes on Product Hunt are skipping the prep work and ignoring feedback. Make sure you have a solid plan, engaging visuals, and a clear value proposition. Plus, always take the time to respond to comments and take suggestions seriously—it can make a big difference :)
Remember, on Product Hunt, avoid the classic blunders like posting at odd hours when everyone's asleep, forgetting to engage with the community, or trying to pass your product off as a cure for the common cold. Steer clear of those and you'll be on the road to Product Hunt glory in no time!
