Hey product hunt, we finished in 4th yesterday after our launch.
One tip that we found was that the people who will upvote your product should be warmed up to the PH community beforehand and engage in lots of communication and interaction before the actual launch of your product.
Second, keep the upvotes coming slowly and consistently rather than all at once. This means using different mediums at different times based on your target audience, their country, and their availability.
Third, keep engaging in interaction in the comments section and reviews. Some products will not have any reviews but many upvotes, whereas some will have a lot of comments but very little upvotes. People love to give feedback and give constructive criticism on PH, so don't be afraid of this!
We will be sure to keep this in mind next time, and best of luck to those who are launching in the near future!
