Pinterest

Pinterest works less like a social network and more like a visual search engine: people arrive with intent — planning a room, a wedding, an outfit, a recipe — and save images to boards for later.

That intent is why it converts well for home goods, fashion, food and craft categories. Pins also have an unusually long life: unlike a feed post that dies in hours, a pin can keep driving traffic for months or years as it resurfaces in search.

Success depends on image quality and text overlay, since the platform's search reads both the image and its description. Vertical images perform best, and linking each pin to a real destination page is what turns saves into traffic.
