Instagram now allows up to five hashtags on a post or Reel, so every tag has to earn its place. This page opens Social media studio's AI Writer with the Instagram hashtag task selected. Describe your post, niche and audience, and get up to three sets of hashtag ideas to copy. The ideas come from your description and the AI's general knowledge, not from live Instagram data, so check each tag before you use it and keep the five that fit best. Generating requires a signed-in Social media studio account and uses AI caption credits from your plan or trial.
Five hashtags: what changed and what it means
For years Instagram allowed up to 30 hashtags on a post. In December 2025 it announced a gradual move to a limit of five for posts and Reels, saying a few specific tags perform better than a long list of generic ones. Instagram has also said that hashtags help people understand what a post is about but don't increase its reach on their own.
So stop thinking in stacks. Five precise tags that describe what the post is actually about beat a wall of popular ones. A suggestion here may list more than five tags, because it is a set of options rather than a final list. Treat each one as a shortlist: keep the most specific tags, drop the vague ones and stop at five.
How to choose your five
Hashtags still come in rough sizes. Broad tags such as #fitness have huge volume and heavy competition, so a post rarely stays visible on them for long. Specific tags such as #strengthtrainingforwomen have smaller audiences that are looking for exactly that subject.
With only five slots, lean specific. A practical mix is one or two broader tags that name your category, two or three specific tags that name the exact topic, and a branded tag if you use one consistently. For a local business, a place-based tag like #brooklynfood often deserves a spot.
Put the specifics in your brief. 'Reel, 20-minute dumbbell workout at home for beginners, women over 40' produces far more useful tags than 'fitness post'.
Check every tag before you post
The AI can't see Instagram. It doesn't know how many posts use a tag today, whether a tag is trending, or whether Instagram has restricted it. Before you post, search each tag in Instagram and look at the top posts. If they match your subject and audience, the tag fits. If the results are off-topic or spammy, or Instagram hides recent posts for the tag, skip it.
Also avoid engagement-bait tags like #likeforlike and #followforfollow, tags so generic they say nothing about the post, like #love or #instagood, and tags from the wrong niche. Choose tags for each post instead of pasting the same five every time.
Where to put your hashtags
Put them in the caption. Instagram hasn't clearly documented whether hashtags in a first comment count toward the same five, so the caption is the safe choice. Many people add them at the end, after the call to action, so the opening lines stay clean.
Hashtags are not the only way people find posts. Instagram search also reads the words in your caption, so a plain phrase that names your topic, such as 'easy weeknight pasta for two', helps too.
Need the caption as well? Switch the 'What would you like to write?' dropdown to the Instagram caption task. Its Hashtags setting can add one to three tags to each caption. If you use Social media studio, you can paste the finished caption into the post composer to schedule it.
