Hashtag Density Checker
Analyze your caption for tag count, density, and flags for overused or potentially banned tags.
Instagram allows up to 30 hashtags per post; its own guidance points to a small, targeted set instead. Paste your caption and find out where you stand: total tag count, how much of the text is tags, and which tags are spam-associated or too generic to do anything for you.
How to use it
- Paste your full caption, hashtags included, into the text box.
- Run the analysis for your tag count, caption length, and tag density.
- Review the color-coded tags: green is fine, amber is overused, red is potentially banned.
- Swap out flagged tags for more specific alternatives.
- Copy the cleaned-up tag list back into your caption.
How many hashtags should you use on Instagram?
The ceiling is 30 per post, but almost nobody should go near it. Instagram's own creator guidance has recommended keeping it to a few targeted hashtags, and the tool's recommendation follows that: 3 to 5 tags that actually describe your content. A caption with 28 tags reads as desperate to people and, more importantly, gives Instagram 28 weak signals instead of a few strong ones.
Hashtags stopped being a growth hack years ago. They still help Instagram categorize your content and surface it in search, which is worth something, but nobody builds an audience on tags alone anymore. Spend five minutes picking accurate ones, then put the remaining energy into the content itself.
What are banned or flagged hashtags?
Some hashtags are so associated with spam and engagement pods that using them can hurt distribution. Tags like follow4follow, like4like, and their many abbreviations signal that a post is fishing for empty engagement, and Instagram has restricted tags like these over the years. This tool checks your tags against a list of known offenders and marks them red.
The amber tags are a different problem. Tags like love or instagood have hundreds of millions of posts, so your content disappears in them within seconds. They aren't harmful, just useless. Replacing them with a specific tag from your niche costs nothing and gives the post a real chance of surfacing somewhere relevant.
One caveat: no external tool sees Instagram's actual restricted list, which changes without notice. Treat the red flags here as a strong warning, and when in doubt, search the tag inside Instagram. If recent posts don't load for it, skip it.
What is hashtag density and why does it matter?
Density here is the share of your caption's words that are hashtags. A caption that's 60 percent tags barely qualifies as a caption. There's no official penalty threshold, but if the tags visually dominate the text, you've inverted the priority. Write the caption for humans first, then add a handful of tags for the machine. Some creators drop tags at the very bottom after a few line breaks, which keeps the reading experience clean and works just as well.
Frequently asked questions
What is the maximum number of hashtags on Instagram?
30 on a feed post or reel caption. Instagram won't publish the post if you exceed that. Comments allow additional tags, though there's little evidence that tags in comments perform differently.
Do banned hashtags still exist in 2026?
Instagram restricts hashtags associated with spam or policy violations, and the list shifts over time. The reliable check is searching the tag in the app: if recent posts are hidden or the tag won't load, avoid it.
Is it better to put hashtags in the caption or the first comment?
Instagram has indicated tags work in both places. Caption placement is simpler and there's no clear performance difference, so it mostly comes down to how clean you want the caption to look.
Why does the tool count fewer hashtags than I typed?
Duplicates are counted once, since repeating a tag adds nothing. If a tag contains characters Instagram doesn't support in hashtags, it may not be detected as one.
Will removing overused tags improve my reach?
Removing them won't hurt, and replacing them with specific niche tags gives your post a chance to rank in searches where competition is realistic. Think of it as reallocating slots, not deleting them.
