Frequently Asked Questions

How many hashtags should I use on Instagram?

Instagram allows up to 30 hashtags, but 5-10 relevant hashtags typically perform best. Using too many can look spammy. Mix popular hashtags (100K-500K posts) with niche ones (10K-100K posts) for optimal reach.

Do hashtags still work on Instagram in 2026?

Yes, hashtags still work on Instagram but their importance has decreased. Instagram now relies more on AI to categorize content. Use hashtags as supplementary discoverability, not your primary growth strategy. Focus on quality content first.

How many hashtags should I use on TikTok?

TikTok recommends 3-5 hashtags per video. Unlike Instagram, TikTok's algorithm relies less on hashtags. Use trending hashtags and niche-specific ones. Always include one trending hashtag when relevant to your content.

Should I put hashtags in comments or caption?

For Instagram, either works—engagement is similar. Putting hashtags in the first comment keeps your caption cleaner. For TikTok, always put hashtags in the caption as the algorithm reads them immediately upon posting.

What are banned hashtags and how do I avoid them?

Banned hashtags are tags Instagram has restricted due to spam or inappropriate content. Using them can limit your reach. Avoid generic tags like #follow4follow. Our generator only suggests safe, effective hashtags.
