Frequently Asked Questions
How many hashtags should I use on Instagram in 2026?
Instagram's own guidelines suggest using 3–5 highly relevant hashtags per post. While the platform allows up to 30, a focused, niche-specific approach tends to outperform spam-style bulk tagging. Test what works for your audience using our generator.
Are these hashtags actually trending?
Our generator curates tags combining broad viral tags (#fyp, #explorepage) with hyper-specific, intent-driven keyword variations to maximize reach and engagement across every niche.
Does this work for TikTok?
Absolutely. TikTok limits bios to 80 characters and recommends 3–5 tags per video. Our tool generates TikTok-optimized bios, short-form captions, and curated tag sets sized just right for the platform.
