Relevant hashtags on Instagram are keywords or phrases that describe the content or theme of a post. They play a crucial role in increasing the visibility and reach of posts. Instagram offers different types of hashtags that can be strategically used to target specific audiences and encourage interactions. These include product and service hashtags like #spatreatment, niche hashtags like #wellnesssouthtyrol for wellness offers in South Tyrol, location hashtags like #southtyrol for regional presence, and event or season-specific hashtags like #weddingvenue for wedding offers. A post can contain up to 30 hashtags, but there is no fixed recommendation due to the changing algorithm. It is essential to choose relevant and appropriate hashtags that reflect the content of the post and appeal to potential guests.
