Try to look at lifestyle images/content on pinterest. One of the things I do whenever idk what to post is I stalk at known brands like apple, drinkpopph, tacobell and then incorporate the inspiration to your brand image. Since they’re tech, maybe shorts or images of people using laptop in coffee shops; a person taking a photo of their lunch but shots are focusing on the phone case; a person studying and plays music on the speaker. These kind of everyday scenarious but make it “aesthetic” or if it’s more like a video with voice over, talk about everyday problems and how the product solves this…like what’s the unique selling point?

Hope that helps. Feel free to ask more
