Effective hashtag strategy in 2024 favors 3-10 targeted, niche-specific tags over the maximum allowed. Instagram: mix high-volume, mid-volume, and niche tags across 5-10 per post. Twitter/X: 1-2 highly relevant tags maximum. LinkedIn: 3-5 professional industry tags. TikTok: 3-5 tags mixing trending challenges with niche community tags. Create 5-10 rotating hashtag sets for your content themes and track performance to refine your strategy quarterly.
