Good hashtags describe your content in the words people actually search for, and each platform treats them differently. This page opens Social media studio's AI Writer with the general hashtag task selected, so it works for any topic or niche, from a product launch to a wedding. Describe the content, the audience and where you will post it, and get up to three sets of hashtag ideas to copy. The AI doesn't see live trends or post counts, so check tags before you use them. A signed-in Social media studio account is required, and each generation uses AI caption credits.
Name the platform in your brief
This task isn't set up for one network, so the AI only knows where the tags will go if you say so. Start your brief with the platform and format, such as 'TikTok video' or 'LinkedIn post', then describe the topic, the audience and any place or event involved. If you want a specific number of tags, say that too.
Posting on Instagram? Switch the 'What would you like to write?' dropdown to the Instagram hashtag task, which is set up for Instagram.
The suggestions come from your description and the AI's general knowledge. It can't see what is trending today, how many posts use a tag or whether a platform restricts one, so look each tag up on the platform before you post.
How each platform treats hashtags
Instagram: up to five hashtags per post or Reel, following a change Instagram announced in December 2025. Specific tags beat generic ones.
TikTok: hashtags go in the caption. A few specific tags that describe the video help more than filler like #fyp, which says nothing about your content.
YouTube: add hashtags to the title or description. Up to three can show near the title, and if a video has more than 60, YouTube ignores all of them.
LinkedIn: hashtags are clickable topics, but they matter far less than the post itself. Two or three relevant professional terms at the end are plenty.
Threads allows one topic tag per post. On X, a hashtag or two is enough. On Facebook, hashtags are optional, and many posts do fine without any.
Branded, event and wedding hashtags
A branded hashtag works when you will use it on every relevant post for months, when it is short enough to remember and type, and when fans or guests are likely to use it too. Good ones are short, easy to say and not already crowded. Long or generic tags, such as #cozyboardgameswithfriends2026 or #runclub, rarely catch on.
The AI can brainstorm these if you give it the raw material. For a wedding, include both names and the date or a pun you like ('Kelly and Sam, June 2027, tying the knot'). For an event, include its name and year. For a campaign, describe the idea in a sentence.
Before you commit, search the tag on each platform you plan to use. If someone already uses it for something else, pick another.
Mix broad and specific tags
Hashtags come in rough sizes. Broad tags such as #fitness or #travel have huge audiences and heavy competition, so a post rarely stays visible on them for long. Mid-sized tags such as #strengthtraining are narrower but still active. Specific tags such as #5amrunclub are small, but the people who browse them want exactly that topic.
Most posts do best with a mix that leans specific: one broader tag for the category, a few specific tags for the exact subject, and a branded tag if you have one. Fewer, better-matched tags beat long lists on most platforms now, and on Instagram five is the maximum anyway.
Refresh your sets now and then. Communities move, and a tag that fit last year may be quiet or crowded today.
