Hashtag Best Practices

  1. Avoid Banned Hashtags

    Instagram and TikTok shadowban certain tags. Always use an AI generator like ours to ensure you're using 'safe' metadata.

  2. Mix Broad & Niche Tags

    Use a mix of high-volume hashtags and hyper-specific niche ones to maximize both reach and targeted discovery.

  3. Limit Use on X/Twitter

    While Instagram thrives on 15+ tags, X (Twitter) performs best with only 1-2 highly relevant hashtags per post.

  4. Hide Your Tags

    On Instagram, keep your caption clean by placing your hashtags in the first comment or far below your main copy.
