Instagram recommends using 3–5 highly relevant hashtags per post, though posts can have up to 30. Research from later.com and Hootsuite consistently shows that 3–10 targeted hashtags outperform posts with 30 generic ones. Quality and relevance matter more than quantity. For Reels, 3–8 hashtags is the current best practice.
Twitter/X recommends 1–2 hashtags per tweet. Using more than 2 hashtags can reduce engagement by up to 17% according to studies, as posts look spammy. Hashtags also consume your 280 character limit, so choose only the most relevant one or two tags.
LinkedIn recommends 3–5 hashtags per post. Unlike Instagram, LinkedIn hashtags work as searchable topics rather than discovery tools. Use a mix of broad category hashtags (#Marketing, #SEO) and niche specific ones (#ContentMarketing, #LocalSEO). LinkedIn will suppress posts that look spammy, so avoid keyword stuffing.
Instagram allows a maximum of 30 hashtags per feed post and 10 per Story. TikTok has no hard limit but recommends 3–5. Twitter has no hashtag limit but character limits apply. YouTube allows up to 15 hashtags in video descriptions — posts with more than 15 have all hashtags ignored.
Yes, but their role has changed. In 2024-2025, Instagram has shifted toward interest-based ranking where hashtags help classify content rather than primarily driving reach. Using 3–5 precise hashtags helps the algorithm understand what your content is about and serve it to interested users. Mass hashtag use (20–30 tags) is no longer recommended.
