Picture this: Your social media marketing team is posting on Instagram like clockwork. Carousels, Reels, Instagram Stories—content’s going out almost daily. The creatives are solid, and the captions are sharp. But when you check the numbers, reach has stalled. Growth feels like a grind.
Engagement is trickling in from the same group of loyal followers. But new eyeballs? Crickets.
Someone on the team floats the idea: “Maybe we just need better hashtags.” It’s a reasonable instinct. An easy lever to pull. And sure, trending hashtags can get you seen. But if your visibility depends on hitting the jackpot with the right tag at the right time, that’s not a strategy; that’s roulette.
If you relate to this, there’s a good chance that the real problem isn’t actually your Instagram hashtags—it’s your discovery engine. Or lack of one. You’re creating content but not building momentum. Not showing up in the right feeds. Not capturing intent when it spikes.
This post will break down how to find trending hashtags on Instagram intelligently—and more importantly, how to plug them into a repeatable system that drives visibility at scale.
What are trending hashtags on Instagram?
Trending hashtags are tags that are currently driving high visibility and engagement across Instagram. They spike when a lot of users post about the same topic, event, or theme, creating a wave of content that the algorithm pushes wider.
However, not all trending Instagram hashtags are created equally.
Some are tied to popular moments: #MetGala, #SuperBowl, #WorldMentalHealthDay. Others are niche movements or social media challenges: #SmallBusinessSaturday, #BehindTheScenes, #BeforeAndAfter. And some are branded hashtags like #ShareACoke or #MyCalvins.
What makes a hashtag “trending” isn’t just volume—it’s velocity. The faster a hashtag gains traction, the more Instagram surfaces it in the Explore page and Reels tabs. That’s where reach comes from: being in the right conversation while it’s taking off.
But here’s the catch: slapping a trending hashtag on unrelated content doesn’t work. The algorithm (and your audience) can sniff that out. So the key isn’t just spotting what’s trending; it’s identifying what’s trending and relevant to your brand.
Say, you run a skincare brand. #GRWM (Get Ready With Me) might be trending because of a celebrity’s post. If your team jumps in with a product-first morning routine reel, it fits. You ride the trend and stay on brand.
Or maybe #MothersDayGifts is trending. If your product lineup includes bundles or gift sets, that’s your lane. Lean in—early.

What makes an Instagram hashtag “trend”?
It’s common to think a hashtag trends when it has a high volume. But volume alone doesn’t drive traction. A hashtag gains momentum fast when it’s timely, culturally relevant, and gathering steam in a specific niche or across the platform.
- Timeliness: It taps into a moment people care about right now. Think: seasonal events, viral challenges, breaking news, or emerging memes.
- Cultural relevance: It reflects something happening in the world—or your industry—that’s resonating emotionally or socially.
- Category-specific traction: It’s not always platform-wide. A hashtag can trend within a niche, like #CleanBeautyTips trending among skincare creators, without hitting the global explore page.
How trending hashtags surface in feeds
Instagram’s algorithm prioritizes content that:
- Uses relevant Instagram hashtags tied to user behavior or interests.
- Shows early engagement (likes, shares, saves) relative to similar content.
- Aligns with momentum—how fast that tag is being used and interacted with across accounts.
When a hashtag checks those boxes, Instagram pushes posts to more feeds, like the Explore page, Reels, and even your followers’ home feeds.
So, visibility isn’t just about adding a trending hashtag to a post; it’s about catching the wave early and pairing it with solid content.
How to spot trending hashtags in real time
To catch a hashtag while it’s heating up—not after it peaks—watch for these signals:
- Rising post velocity: A sudden uptick in how often a tag appears in posts, especially from creators in your niche.
- Influencer usage: When creators with reach start using a tag consistently, it’s often a cue that the trend is gaining momentum.
- Brand adoption: Once brands start participating, especially outside their usual campaign cycles, it’s a sign the hashtag is moving beyond the organic buzz.
You can monitor these signals manually (by checking the Explore page and key accounts in your niche) or use tools like:
- Flick – Tracks hashtag performance and gives real-time velocity data.
- Later – Offers hashtag suggestions and performance metrics.
- Meta Business Suite – Includes engagement and reach breakdowns by tags, directly from Instagram itself.
These tools don’t decide for you, but they surface patterns fast, so you can act before the trend gets saturated.

Why trending Instagram hashtags alone don’t work anymore
It’s easy to think that if you use the right mix of trending hashtags, the reach will follow. This is tempting, especially when your team puts out solid content and does not see the growth to match.
So marketers fall into familiar habits:
- Recycling the same 30 Instagram hashtags for every post, regardless of content type or context.
- Copying tags from competitor accounts without checking if they’re actually working.
- Using generic high-volume Instagram hashtags like #MotivationMonday that are saturated and irrelevant.
- Chasing “top hashtags” lists without considering your brand, target audience, or goals.
At one point, this worked. Now? Not so much.
Instagram’s algorithm has evolved. It no longer rewards volume or popularity for its own sake. It prioritizes context: Does your post belong in the conversations that the trending hashtag represents? Is it earning engagement (saves, shares, comments) early? Does it fit what users interacting with the tag are actually looking for?
If you’re using #WellnessTips on a generic product photo, the algorithm (and your target audience) will ignore it. Worse, repeated misuse or stuffing of irrelevant hashtags can actually suppress reach.
That’s why you should think of hashtags as part of your digital marketing strategy, not as accessories for your content.
What actually works is aligning trending hashtags with:
- The content format (Reel vs. static post vs. carousel)
- The message or theme of the post
- Search intent and cultural moments
- Niche relevance (not just broad popularity)
However, doing this consistently requires time, pattern recognition, and a strategic approach. And that’s the real issue for most internal teams: no one owns it.
Most lean, growth-stage teams do a great job with content creation. But the visibility layer—the part that connects content to discovery—is often nobody’s job. This means hashtags become guesswork.
That’s why you need an Instagram expert.
At MarketerHire, we’ve seen the difference when brands bring in someone who owns an Instagram growth strategy, especially the discovery layer. They don’t just pick better Instagram hashtags; they build systems that compound reach over time.

How to find trending hashtags on Instagram—and use them
At high-growth brands, Instagram hashtags are part of the growth engine. The best teams don’t just chase what’s trending; instead, they build systems to surface the right tags, plug them into relevant content, and track performance like any other growth lever.
Let’s walk through what that looks like in practice.
1. Listen where trends actually start.
Most trends don’t start in your social inbox or on “top hashtag” blogs. They start with creators, micro-influencers, and niche communities that shape culture before it hits the mainstream.
Start by tracking 10-15 accounts across your category and adjacent niches. Watch what hashtags they’re testing, what kinds of content those tags appear on, and how quickly engagement follows.
For example, a clean beauty brand notices several mid-sized creator accounts using #BarrierRepair in their routines. The brand builds a carousel post breaking down skin barrier science and publishes it while the trend still gains momentum. That early alignment gets them strong engagement and visibility, without paid promotion.
It also pays to watch TikTok. Reels often echo TikTok trends with a slight delay, so if you see a format or phrase gaining traction there, it’s likely to cross over. Get ahead of it on Instagram while others are still catching up.

2. Spot trends based on velocity, not just volume.
A trending hashtag is one that has momentum. That means usage is ramping up quickly, often within a niche, even if it hasn’t yet reached viral status.
With tools like Flick, you can track hashtag growth rates and sort them by performance signals like engagement rates and recent activity. This is especially useful for finding under-the-radar tags that are just starting to pop.
For instance, if you’re a fitness brand and you see #HotGirlWalkTips jump from 5,000 to 8,000 in a few days, you could quickly film a 30-second Reel on walking posture and hydration and tag it accordingly. Because you’re early and the content fits the theme, you could land on Explore and hit multiple of your average views.
3. Match hashtags to audience intent, not just content.
Trending hashtags don’t matter if they’re attracting the wrong crowd.
Instagram hashtags should act like filters, connecting your content to people who are not only interested in the topic but also interested in how you’re talking about it. That means choosing tags based on intent signals.
Let’s say you’re marketing a professional development course. Using #SideHustle might help you reach a wider audience, but it attracts a casual, hustle-culture crowd. Instead, #CareerPivot might resonate better with professionals actively looking to transition careers—your actual buyer. That one decision shifts not just who sees your content, but who converts.

4. Test Instagram hashtags like you would test messaging or CTAs.
Hashtags aren’t a set-it-and-forget-it element. Like any growth lever, they must be tested, measured, and optimized.
Create multiple trending hashtag sets, each a strategic blend of high-volume, mid-volume, niche, and branded tags. Then, rotate them across similar posts to see what drives real results: reach, profile visits, saves, DMs, and website taps.
For example, if you’re a coffee brand, you might test one set of Instagram hashtags with broader appeal, like #CoffeeLovers and #MorningRoutine, and another set focused on specialty coffee culture, such as #ThirdWaveCoffee and #PourOverTips. If you notice that the specialty set drives fewer views but generates more profile clicks and saves—strong signals of higher intent—you can use that insight to fine-tune future campaigns.
5. Organize hashtags by content type, not just topic.
The right hashtags shouldn’t live in a giant one-size-fits-all doc.
Different types of content attract different types of intent, and your tags should reflect that. Reels may thrive with broader lifestyle or location tags, while static posts often benefit more informational or community-focused ones.
For example, if you’re a fashion brand, you might tag your outfit Reels with broad discovery tags like #OOTD or location-based ones like #StreetStyleNYC. But when you post about sustainability or production, you switch to tags like #SlowFashion and #EthicalStyle. These posts might not get as many likes, but they attract followers who care about your values, and they’re more likely to stick around and engage long-term.
Organize your Instagram hashtag strategy the way you organize your content calendar: by intent, format, and funnel stage.
6. Block a weekly trend mining ritual.
Block off 30 minutes every week to scan for signals.
Scroll through your niche hashtags, check what’s landing on Explore, audit competitors, and look at your last 10 posts to see which Instagram hashtags actually delivered. Or you can use tools like Later to identify usage spikes and track performance over time.
Say you’re a home décor company and you notice a renewed wave of content under #Shelfie. Instead of spinning up a new shoot, you can repost a high-performing shelf styling carousel from six months ago, this time tagged appropriately. That small change can lead to a spike in saves and Explore reach, all without you creating anything new.
Trends are fast-moving. Without regular check-ins, you’ll always be reacting instead of leading.
Instagram hashtag best practices
Before you start plugging hashtags into every post, it’s worth dialing in a few best practices that high-performing brands follow to keep their hashtag strategy clean, efficient, and effective.
1. Stick to 3-5 hashtags per post.
Instagram has confirmed that using 3–5 relevant hashtags per post is the sweet spot for discovery, not 30. Overstuffing captions with too many hashtags not only looks messy, but can also dilute your reach by confusing the algorithm about what your post is actually about.
Keeping it lean forces you to be strategic about the tags you choose and sends stronger, more focused discovery signals.
2. Use a mix of related hashtags.
Instead of using five hashtags that all say the exact same thing, build a small cluster around your main focus.
For example, if your main hashtag is #CleanBeauty, related tags might be #NonToxicSkincare, #GreenBeauty, and #EcoFriendlyLiving. This broadens your discoverability without straying too far from your core message.
3. Create and promote your own branded hashtag.
Don’t just ride other people’s conversations—start your own.
Branded hashtags are an easy way to tie user-generated content, campaigns, and community mentions back to your brand. Think #ShareACoke (Coca-Cola) or #AerieREAL (Aerie). Even a simple branded tag like #[YourBrandName]Tips or #[YourBrandName]Life can build momentum over time.
Use your branded hashtag consistently in Instagram posts, Stories, and bios, and encourage customers or followers to use it too.
4. Use a hashtag generator if you’re stuck.
If the Instagram search bar isn’t surfacing useful, effective hashtag suggestions, use hashtag generator tools to speed up your research. Tools like Hashtagify and Inflact can help you uncover niche tags you wouldn’t find manually, and inspire smarter combinations.
That said, always double-check suggested hashtags for relevance. A generator is a starting point, not a final answer.
5. Refresh your hashtag strategy regularly.
Even the best-performing hashtags lose power over time. Trends shift, communities move, and what once drove reach might plateau.
Plan to audit and refresh your hashtag banks at least once a quarter. Look at which tags are still generating discovery and engagement, and don’t be afraid to retire or replace underperformers.
6. Avoid using banned or spammy hashtags.
Some hashtags get shadowbanned or flagged because they attract spammy content or violate Instagram’s community guidelines. Using these, even unintentionally, can suppress your reach across the board.
Before adding a hashtag to your strategy, do a quick search. If the tag doesn’t show up properly in search, or if Instagram gives a “posts hidden” warning, skip it.
Case study: Jillies
Brands using MarketerHire’s social media experts have doubled their organic reach in under 60 days—without increasing post volume.
Don’t believe me? Here’s the story of one of our customers: Jillies, a company that sells dress weights.
When Jillian Tessler launched her direct-to-customer brand, Jillies, she quickly realized that building a product and launching a Shopify store was the easy part—growing the brand while juggling a full-time job was much harder. She knew marketing would be critical, but was hesitant to waste money on freelancers who couldn’t meet her standards. Rather than spread herself thin across multiple channels, Jillian decided to seek expert help.
A friend recommended MarkerterHire, and when Jillian reached out to us, we matched her with the ideal marketer: a paid social freelancer with e-commerce experience in women’s brands. Within just two and a half weeks, Jillies saw a major spike in orders.
Excited by this outcome, Jillian returned to hire an organic social media manager to keep new followers engaged with consistent, thoughtful content.
Thanks to these freelancers, Jillian built a strong, sustainable brand presence, without burning out.
“I had ‘to create a content calendar’ on my to-do list for six months,” said Jillian. “Within 72 hours, the MarketerHire freelancer had an entire posting strategy built out. Now, my grid looks more organized and more thoughtful. Anyone who was following the Jillies before MarketerHire and following now, it's like night and day.”

How to grow your brand with Instagram hashtags
Once you have a system in place, Instagram hashtags stop being a guessing game and start becoming a predictable growth lever.
Here’s how to use trending hashtags for long-term brand growth:
1. Expand your reach beyond followers.
Most Instagram posts are only seen by people who already follow you. Hashtags change that.
When used strategically, trending hashtags can place your content in front of intent-rich, non-following users through Explore, hashtag search, and suggested Reels. The key is aligning each tag with the content’s actual message and audience interest, not just what’s popular that day.
For example, a food brand posting a recipe reel might skip broad tags like #Dinner and go for hashtags like #EasyWeeknightMeals or #OnePotRecipe that show up in feeds of people actively saving and sharing similar content.
2. Build authority in your niche.
Using consistent, high-quality hashtags in your space helps Instagram associate your content with a specific topic or vertical. Over time, that improves your discoverability for Instagram users who engage with that category even when they don’t follow you.
This is where mid-volume and niche hashtags matter. Instead of making countless Instagram posts with the broad hashtag #Marketing, a B2B SaaS brand can use niche tags like #B2BMarketingTips or #SaaSGrowthStrategies to show up in a more targeted feed, where their expertise stands out and their content lasts longer.

3. Drive engagement by matching tag intent to content type.
Different types of content serve different purposes: Reels for reach, carousels for saves, and Instagram Stories for interaction. Matching Instagram hashtags to each format’s intent sharpens performance across the board.
Let’s say you’re posting a tip carousel. Using hashtags like #MarketingTips, #ContentStrategy, or #InstagramGrowthTips positions the content for educational discovery. That increases the odds of saves and shares, especially if the tags are ones Instagram users already engage with for learning.
4. Use trending tags to tap into cultural relevance.
Timely hashtags tied to events, seasons, or cultural moments can act like accelerants. When used with intention, they let your brand enter bigger conversations in a way that feels natural.
For instance, during Mental Health Awareness Month, a wellness brand can use #WorldMentalHealthDay or #MentalHealthMatters alongside a post about self-care routines. This aligns the brand with a broader narrative while still staying true to its mission, and can lead to cross-pollination with new, like-minded audiences.
5. Track, test, and iterate like a growth channel.
If you’re not tracking how trending hashtags perform and what drives reach, clicks, and saves, you’re leaving insights on the table.
You can use Flick or Meta Business Suite to monitor hashtag analytics:
- Which hashtags consistently show up in top-performing Instagram posts
- Which ones drive the most profile visits or website taps
- How different sets perform across post types
Then refine your campaign hashtag banks. Retire underperformers. Test new combinations. Over time, this creates a compounding effect where every Instagram post performs a little better than the last.
6. Stack relevant hashtags with other discovery tools
Hashtags work best when paired with other Instagram signal rewards, like audio, location tags, creator collaborations, and even CTA copy in captions.
If a fashion brand posts a Reel with trending audio, geo-tags it with a major city, and uses niche tags like #MinimalStyle or #WeekendLook, the algorithm has multiple reasons to surface the content across different discovery surfaces.
It’s not just about hashtags. It’s about stacking signals so the algorithm knows who to show your content to, and why.
