How to get keywords/ selling features to show up under a product listing on homepage?

[AlpineDogCo]

Hey! 

I'm looking to find a way to get a keyword or two to show up under or over each product on my product page. For example, a product that has extra padding would say "extra comfortable" or a product would say "puppy friendly."

Ideally I'm thinking an app would be the route to take for this, but I can't for the life of me find an app that provides this embedded service. Can someone point me in the general direction I should be going? I feel like I'm getting lost trying to find a way to do this. I tried to go about changing the "sale" sign but it changes it for all items, not specified to one.

Hello @AlpineDog

Please elaborate your requirement in detail. If you want to only show keyword with products so it is possible without an application, this will handle by liquid code. so you need to hire a shopify expert.
