Adding tags to your products
To add a tag to your product, go to the SHARE tab of your product's edit flow:
And scroll down to the Discover Settings:
Adding tags to your products helps accomplish two things for you and your customers:
1) If you have enabled Gumroad Discover in your settings menu, adding tags to your individual products will help Gumroad's hardworking selling elves display your products to customers of similar products. Thereby, your product will be discovered by new customers.
2) If you have more than 10 products, your products' tags will appear on your Gumroad profile, allowing your customers to filter your page and find the product they're looking for.
