Before posting, there are a few things you can do to make sure your posting process goes smoothly:
Feel free to post your own product! It's not necessary to have someone else post it for you. In fact, posting it yourself gives you full control over the launch.
Is your post an update or additional feature to a product/company that's been previously posted or is it a brand new product?
If your post is related to a product that's been previously posted, you will need to wait at least 6 months after the previous launch and ensure that there has been a significant update before the product will be eligible to be posted again.
This includes features or updates to previously posted products and additional products/services from the same company.
If your product has never been on Product Hunt before, then you're good to go!
It's also a good idea to have all media related to the post ready. This includes uploading YouTube videos ahead of time to make sure they're fully uploaded and ready to be viewed.
Have a list of team members you'd like to add to the post will also be handy.
