Instagram says a post or Reel now takes up to 5 hashtags (December 2025, Social Media Today, Dec 19, 2025). It used to be 30. So the old trick of a big block of tags is gone. Here is how to make 5 count.
What hashtags do now
- A hashtag is a label. It tells people and the app what the post is about.
- Your caption, the words on screen and what people do after they watch are labels too.
- People type words into the search bar on Instagram and TikTok. Clear words in your caption help you get found.
- A tag will not save a weak post. The first seconds and the value of the post do the heavy work.
How many hashtags to use
- Instagram: up to 5. That is what Instagram says now.
- TikTok: a few that fit. Mix one broad tag with a few specific ones.
- YouTube Shorts: a couple of tags, plus a clear title and description with the words people search for.
- Each tag should really describe the post.
How to pick your 5
- 1 or 2 broad tags for your topic. Lots of posts, lots of people.
- 2 or 3 niche tags for exactly what you do. Fewer posts, closer fans.
- 1 community tag your audience follows or checks.
Put keywords in your caption
- Use the words someone would type to find your post.
- Post quick dinners? Say "quick weeknight dinner" in the caption and on screen.
- Say it out loud in the first seconds too, if the video has a voice.
- This is not stuffing. It is just saying clearly what the post is.

Tags to skip
- Tags that do not fit, just to ride a trend. They bring the wrong people.
- Banned or flagged tags. If you think one is flagged, drop it.
- The same block on every post. Pick tags for each post instead.
Keep a few tag groups, one per theme. A simple content calendar helps you match a group to each post.
Check if your tags help
- Instagram and TikTok can show where your views came from.
- If very few views come from hashtags, spend that time on hooks and captions instead.

- Write the caption in plain, searchable words.
- Put your main keyword on screen and in the first spoken seconds.
- Pick tags for each post, not one block for all.
- Spend most of your effort on the hook.
- Check your analytics and adjust.
