Strategy tip
For Instagram Reels, fewer targeted hashtags (5–10) outperform the 30-hashtag spam approach. Quality over quantity wins here.

The 3-tier hashtag strategy balances reach and relevance. Mega tags (over 1 million posts) put your content in front of large audiences but face heavy competition. Mid-tier tags (100K–1M posts) hit a sweet spot — enough volume to matter, competitive enough to be reachable. Niche tags (under 100K posts) attract smaller but more targeted audiences who are genuinely interested in your content, driving stronger engagement rates.
Instagram Reels benefit from a tighter hashtag set (5–10 tags) rather than the old 30-tag approach. The algorithm now prioritizes content quality and watch time over hashtag volume. Mixing 2 mega tags for broad discovery with 3 mid-tier and 4 niche tags gives your Reel the best chance of being surfaced to new audiences without looking spammy.
TikTok hashtags work differently from Instagram. #fyp and #foryoupage are widely used but don't guarantee placement on the For You Page — the algorithm weights watch time, replays, and shares far more heavily. What hashtags do well on TikTok is help the algorithm categorize your content correctly. A few targeted niche tags tell TikTok who your content is for, increasing the chance it reaches the right audience.
Frequently asked questions
Do hashtags still work on Instagram?
Yes, but their role has shifted. Instagram confirmed in 2023 that hashtags help categorize content rather than directly drive reach. The algorithm now prioritizes content people are likely to engage with based on their behavior. Hashtags work best when they're specific to your content — broad mega tags like #fitness are useful for categorization, but niche tags like #morningworkout connect you with a smaller, more engaged audience.
What's the difference between Instagram and TikTok hashtag strategy?
Instagram hashtags primarily affect search discovery and the Explore page. A tiered mix of mega, mid, and niche tags gives you the widest surface area. TikTok's algorithm is more interest-graph driven — it learns what content to show users through engagement signals (watch time, replays, shares). On TikTok, hashtags mainly signal content category. Using 3 core tags plus 3–4 targeted niche tags is typically more effective than using 20+ broad tags.
How many hashtags should I use on Instagram Reels?
Instagram's own guidance recommends 3–5 hashtags, though creators report success with up to 10. The shift away from 30-hashtag sets happened around 2022 when Instagram began treating excessive hashtag use as a spam signal. For Reels, 5–10 targeted hashtags — 2 mega, 3 mid, and 4 niche — tends to outperform the old 30-tag approach.
Should I always use #fyp on TikTok?
#fyp, #foryoupage, and #foryou are among the most-used tags on TikTok, which means they also carry virtually no differentiation signal. They don't hurt, but they don't guarantee For You Page placement either. TikTok's algorithm places far more weight on watch time, completion rate, shares, and saves. Focus on niche-specific tags that accurately describe your content — those give the algorithm better context and tend to attract higher-quality engagement.
Can I use the same hashtag set every post?
Rotating your hashtag sets is generally recommended. Using the exact same 20 hashtags on every post can flag your account as spammy to Instagram's algorithm. Keep your core brand and niche tags consistent (4–6 tags) but swap out the mid-tier and niche-specific ones based on each post's topic. On TikTok, the algorithm is less sensitive to repetition, but updating niche tags to match each video's specific topic will improve content categorization.
Where should I put hashtags on Instagram — caption or first comment?
Either works equally for algorithmic purposes — Instagram confirmed hashtag placement doesn't affect reach. In the first comment keeps your caption cleaner and more readable; in the caption ensures they're always there even if the comment doesn't post. Most creators use the caption for 3–5 key tags and optionally add more in the first comment.
How do I find good niche hashtags for my content?
Look at what hashtags successful creators in your niche use on their top-performing posts. Instagram's search feature shows post counts for any hashtag — aim for under 500K for niche tags, 100K–2M for mid-tier. TikTok's Discover tab shows trending hashtags by category you can filter by niche.
Do banned or restricted hashtags hurt my posts?
Yes — Instagram has a list of banned and restricted hashtags that trigger reduced distribution or shadow limits when used. You can check if a hashtag is restricted by searching it on Instagram: if the Recent tab is missing (showing only Top), the hashtag may be restricted. Avoid banned hashtags entirely and rotate out any that aren't showing Recent posts.
