How TikTok Uses Hashtags
On Instagram, people actually browse hashtag pages. On TikTok? Nobody does that. The algorithm already understands your video from the visuals, audio, and on-screen text. It does not need hashtags to categorize you.
So why bother? Because hashtags are an extra signal. A confirmation. They nudge the algorithm in the right direction and can give your video a small push toward the right audience. Think of them as labels, not billboards.
Three relevant hashtags beat thirty generic ones. Every single time. Precision over volume.
Hashtags That Hurt Your Reach
Some hashtags are not just useless — they are actively working against you. If you are using any of these, stop:
#fyp, #foryou, #foryoupage
These are so overused they carry zero signal. The algorithm ignores them completely. They take up character space that could be used for relevant tags.
#viral, #trending, #blowup
Wishful-thinking hashtags. They do not make your video go viral. They signal to the algorithm that you do not know your audience.
Extremely broad niche tags (#fitness, #food)
Too competitive. Your video competes against millions of others. The algorithm has no reason to surface your video for this tag over established creators.
Irrelevant trending hashtags
Using a trending hashtag that has nothing to do with your content confuses the algorithm. It shows your video to the wrong audience, they scroll past, and your video dies.
The Hashtag Formula That Works
Keep it simple. 3-5 hashtags per video. That is it. Follow this formula and stop overthinking it:
// The 3-5 hashtag formula
1. Niche tag (1-2)
Specific to your niche. #personalfinancetips, #homeworkouts
2. Topic tag (1-2)
Specific to this video's topic. #creditscorefix, #legday
3. Format tag (0-1)
Describes the content format. #learnontiktok, #storytime
Done. No filler. No #fyp. Every tag should earn its spot by telling the algorithm exactly who should see this video.
Finding the Right Tags for Your Niche
- •Search your niche keyword on TikTok and look at what hashtags top-performing videos use — not the biggest accounts, but mid-size creators who are growing
- •Check the "related hashtags" that TikTok suggests when you type in a tag — these are algorithmically associated tags
- •Look for hashtags with 10M-500M views — big enough to have audience but small enough to not be oversaturated
- •Watch your analytics to see which hashtags correlate with higher views — TikTok shows you traffic sources including hashtag pages
- •Update your hashtag set monthly — what works changes as trends shift and new tags emerge
Hashtags in Your Caption
You get 2,200 characters in your caption. Do not waste them all on hashtags. The caption is for humans. The hashtags are for the algorithm. Prioritize accordingly.
- •Write your caption first, add hashtags at the end — the caption is for humans, hashtags are for the algorithm
- •Do not sacrifice caption quality for more hashtags — a strong caption drives more engagement than extra tags
- •If you can work a hashtag naturally into your caption, do it — but do not force it
- •Some creators put hashtags in comments instead of captions — this works but there is no proven advantage either way
The Bottom Line
Hashtags are the least important factor in TikTok distribution. Not even close to your hook, watch time, or engagement rate. But they cost you nothing and give the algorithm a small nudge. So use the formula, pick 3-5 relevant tags, and move on.
If you are spending more than 2 minutes picking hashtags, stop. Spend that time writing a better hook instead. That is what actually moves the needle.
