How many hashtags should I use on Instagram? +
Instagram allows up to 30 hashtags per post. However, research and creator advice suggests that 3–10 relevant, targeted hashtags often outperform using the maximum 30. Instagram itself has recommended using 3–5 hashtags for best reach. Avoid using the same 30 hashtags on every post, as this can be flagged as spam behavior.
How many hashtags can I use on Twitter/X? +
Twitter/X allows up to 10 hashtags per tweet, but best practice is to use 1–2 highly relevant hashtags. Twitter's own research found that tweets with 1–2 hashtags get 21% higher engagement than those with 3 or more. Too many hashtags make tweets look spammy and reduce readability.
Do hashtags help with reach on TikTok? +
Yes, hashtags help TikTok's algorithm understand your content and show it to interested users. TikTok allows up to 20 hashtags. Best practice is to use a mix of: 1–2 broad trending hashtags (high volume), 2–3 niche hashtags related to your specific topic, and 1 branded hashtag. Avoid overloading with hashtags that aren't relevant to your video.
What happens if I use too many hashtags? +
Going over a platform's hashtag limit will usually result in your post failing to publish or the excess hashtags being ignored. Even within limits, using too many hashtags can reduce engagement — posts can look cluttered and spammy, which reduces genuine interaction. Always prioritize quality and relevance over quantity.
Should I put hashtags in the caption or in the comments? +
On Instagram, both work equally well for reach — hashtags in the first comment are just as effective as hashtags in the caption. Many creators prefer placing hashtags in the first comment to keep their caption clean and readable. On other platforms like Twitter/X and LinkedIn, hashtags work best when placed naturally within the caption text.
