Yes, hashtags can significantly increase the visibility of your Instagram posts. Research and include relevant hashtags in your captions to reach a broader audience. Use a mix of popular hashtags related to travel, vacation rentals, and your location, as well as niche-specific hashtags that align with the unique aspects of your property. However, avoid using too many hashtags, as it can make your captions appear cluttered. Aim for a balance between relevance and readability.
