The mix

Three Kinds of Tags in Every Set

RecurPost’s Instagram Hashtag Generator reads a short keyword or content description and returns a ready-to-use set of Instagram hashtags. RecurPost’s generator blends three kinds of tags, i.e., discovery, niche, and engagement, into every set. Broad discovery tags are ones many accounts in a niche already use. Niche tags tie directly to the post’s specific topic. Engagement tags are picked to prompt replies and saves rather than reach alone.

The range

How Many Instagram Hashtags to Use, and What Mix

Instagram allows up to 30 hashtags per post, but RecurPost’s generator caps the output at 15 tags.

The cap for a single generated set

Supposedly, one agency runs a twelve-account client roster. Three of those accounts belong to small studios with fewer than 5,000 followers each. Two belong to larger, multi-location brands with an established following. The three studio accounts do better with a niche-heavy mix. Niche tags are specific enough that a post can rank inside a small, relevant hashtag community instead of getting buried under millions of generic posts. The two established brand accounts can lean on broader discovery tags because their existing engagement already helps a post surface inside a busier hashtag feed.

Applying the same 15-tag list to all five accounts ignores that difference. A studio account gains little from a hashtag with ten million posts already attached to it, and a large brand account gains little from a hashtag so narrow that almost nobody searches it.

The workflow

What RecurPost's Instagram Hashtag Generator Does

Using RecurPost’s Instagram Hashtag Generator takes four steps.

Describe the post

Type a short description or keyword for the post; RecurPost needs only a phrase, not a full caption.

Choose the count

Choose how many hashtags to generate, up to RecurPost's maximum of 15 tags per set.

Generate the list

RecurPost returns an Instagram-ready mix of discovery, niche, and engagement tags.

Copy and publish

Copy the tags into the Instagram caption or comment, then publish or schedule the post.

For instance, a freelance social media manager batch-scheduling five client Instagram accounts on a Sunday night can generate a fresh tag set for each post without logging into anything beyond RecurPost’s Instagram Hashtag Generator itself.

From tags to schedule

Getting Hashtags Into a Scheduled RecurPost Post

RecurPost’s Instagram Hashtag Generator runs outside the scheduler, so getting the generated set into a post requires a manual copy-paste step.

For example, an agency scheduling a client’s Reel and a static carousel for the same week can generate two different tag mixes, one for each post type, then bulk-schedule both through RecurPost’s scheduling and publishing tools in a single sitting. RecurPost’s AI content tools can also draft the caption, so the hashtag set and the caption come from the same workflow instead of two separate tabs.

The Instagram Hashtag Generator is one of eight free tools inside RecurPost’s social media scheduler, built to feed directly into scheduling rather than live as a stand-alone side project. RecurPost also runs a matching hashtag generator for nine other platforms, including Facebook, TikTok, X, YouTube, Pinterest, Threads, LinkedIn, Bluesky, and Google Business Profile, each tuned to that platform’s own tagging norms.

Instagram allows up to 30 hashtags per post. RecurPost’s generator produces up to 15 tags per run, enough to build a niche-heavy mix for a small account or a discovery-heavy mix for a larger one without maxing out Instagram’s limit on every post.

Yes. RecurPost’s Instagram Hashtag Generator is free with no sign-up or payment required. The generator works directly in the browser and doesn’t require a RecurPost account.

RecurPost runs a separate hashtag generator for each of nine other platforms, including Facebook, TikTok, X, YouTube, Pinterest, Threads, LinkedIn, Bluesky, and Google Business Profile. Each version is tuned to that platform’s own hashtag norms rather than reusing the Instagram mix.

RecurPost lets you copy the generated hashtag set into its Instagram composer alongside the caption, then schedule or bulk-schedule the post as usual. It also lets you save the frequently reused sets to a RecurPost Bag of Tags so the same mix is one click away on the next post for that account.
