Instagram hashtags: how many to use and which ones

Hashtags are a categorising tool. They do not make a weak post go viral, but the right ones help the right people find a good one, especially for small accounts that have no other way to be discovered.

How many should you use?

Instagram allows up to 30, but most creators do better with a small, relevant set of 3 to 8. A long block of unrelated tags looks spammy and adds nothing. Use our caption counter to check your count.

Mix sizes

Tag size	Posts using it	Role
Niche	Thousands	Easier to appear in; attracts the right audience
Mid	Tens of thousands	A balance of reach and competition
Broad	Millions	Useful for context, hard to rank in

Add local tags

For businesses, city and area tags are valuable: #MumbaiFoodie, #DelhiWeddingPhotographer, #BangaloreStartups, #PuneCafes. Local audiences convert better than global ones, and fewer people compete for them.

Build a tag bank

1. Search your main topic on Instagram and note related tags.
2. Check how many posts each has and how recent the top posts are.
3. Group your tags into three or four themed sets.
4. Rotate sets across posts instead of pasting the same block.

Mistakes to avoid

• Copying the same 30 tags on every post.
• Using banned or spammy tags that can limit a post’s distribution.
• Tags unrelated to the post just because they are popular.
• Putting tags in the middle of the caption where they break reading.

Check what works

Open Insights on a post and look at impressions “from hashtags”. Keep the tags that bring reach and drop the ones that do not. Review every month.
