How Hashtags Work on Instagram
When you add a hashtag to your post (either in the caption or the first comment), Instagram's algorithm immediately indexes it. That post then appears on the corresponding hashtag page, which has two key tabs: "Top" and "Recent."
- The "Top" Tab: This is the holy grail. It's an algorithmically curated feed of the best-performing posts for that hashtag. Getting here means your post had high engagement quickly after posting. The "Top" tab is a mix of recent posts and all-time top performers.
- The "Recent" Tab: This is a chronological feed of every single post using that hashtag, from the newest to the oldest. Your post will appear here immediately but will quickly get buried as new content is published.
The goal of any hashtag strategy is to first appear in the "Recent" tab and then, if the post resonates, get promoted to the coveted "Top" tab for maximum, sustained visibility.
Types of Instagram Hashtags
Not all hashtags are created equal. Using a mix of different types is the key to a balanced and effective strategy. Think of it as a pyramid.
Branded Hashtags
This is a unique hashtag you create for your business, campaign, or even for yourself. Its primary purpose is to collect user-generated content (UGC) and build community.
Examples: #JustDoIt
(Nike), #ShotOniPhone
(Apple), #OptOutside
(REI). For a local bakery, it could be #MariasSweetBites
.
Community Hashtags
These are hashtags that connect people around a shared interest, hobby, identity, or industry. They are fantastic for finding your niche audience.
Examples: #Bookstagram
, #PlantMom
, #VanLife
, #FemaleEntrepreneur
.
Campaign Hashtags
Similar to branded hashtags but usually tied to a specific, time-bound marketing campaign or contest.
Examples: A clothing brand running a contest might use #MyStyleWithBrandXSpringContest
.
Niche Hashtags
These are more specific than community hashtags. They describe exactly what is in your photo or the specific topic you're addressing.
Examples: Instead of the broad #Food
, use #VeganGlutenFreeRecipes
or #SourdoughBaking
.
Trending Hashtags
These are popular hashtags that are surging in popularity, often tied to current events, holidays, or viral memes. Use them wisely and only if relevant.
Examples: #MondayMotivation
, #ThrowbackThursday
(#TBT), #WorldPhotographyDay
.
Best Practices for Using Instagram Hashtags
Now that you know the types, how do you use them effectively? Let's break down the rules of the road.
Optimal Number of Hashtags
Instagram allows up to 30 hashtags per post. But should you use all 30? The answer is: it depends. The "right" number is a hotly debated topic.
- The Case for Fewer (5-10): Looks cleaner, more focused, and is less likely to be flagged as spammy.
- The Case for More (20-30): Maximizes discoverability across multiple categories and audiences.
- The Verdict: Test and see what works for your audience. Start with a mix of 15-20 well-researched hashtags. Instagram itself has stated that "it's about using the right hashtags," not the number.
Placement: Caption vs. Comments
Does it matter where you put them? From a functional perspective, no. Instagram's algorithm indexes hashtags whether they are in the main caption or the first comment. The difference is purely aesthetic.
- Caption Pros: Immediate indexing. Some argue it shows the algorithm your content is fully formed from the start.
- Comment Pros: Looks cleaner and keeps the focus on your caption copy. Just make sure you post the hashtag comment immediately after publishing.
Common Mistakes to Avoid
- Using Banned or Shadowbanned Hashtags: Some hashtags are banned due to inappropriate content. Using them can limit your post's reach. Always search a hashtag before using it.
- Being Too Generic:
#Love
has over 2.2 billion posts. Your photo will disappear in milliseconds. Avoid the massive, ultra-competitive tags unless you have a massive following.
- Using Irrelevant Hashtags: Don't use
#DogsofInstagram
on a picture of your lunch. It's spammy and annoys users.
- Using the Same Set for Every Post: This is lazy and ineffective. Your hashtags should be as specific and relevant to each individual post as possible.
Instagram Hashtag Strategies
This is where we move from theory to action. How do you build a strategy that actually works?
Increasing Reach and Engagement
Use a mix of hashtag sizes, often called the "Hashtag Pyramid" or "Hashtag Ladder":
- 3-5 Broad (High-Competition): 100k β 1M+ posts. (e.g.,
#TravelBlogger
)
- 5-10 Medium (Mid-Competition): 10k β 100k posts. (e.g.,
#SoloFemaleTravel
)
- 5-10 Niche (Low-Competition): 1k β 10k posts. (e.g.,
#TravelPortugal
)
This mix gives you a shot at the competitive tags while also giving you a much higher chance of ranking in the "Top" tab for smaller, niche tags.
Building Community with Hashtags
Actively use and engage with your community and branded hashtags. Follow your branded hashtag, feature user-generated content on your profile, and engage with posts that use your community hashtags. This turns a tag from a discovery tool into a vibrant community hub.
Creating a Branded Hashtag
Keep it simple, memorable, and unique. Promote it everywhere: in your bio, on your stories, in your captions, and even on your packaging and marketing materials. Run a contest encouraging people to use it for a chance to be featured.
Seasonal and Event-Based Hashtags
Leverage holidays, seasons, and current events. #HappyNewYear
, #SpringFashion
, #Olympics2024
. These tags have built-in momentum and search volume during specific times.
Case Studies and Examples
Learn from successful hashtag campaigns that made an impact.
Successful Branded Hashtag Campaigns

- #AerieREAL by Aerie: Promoting body positivity, this campaign banned photoshop and encouraged users to share real, unretouched photos. It built a powerful community and drastically improved brand perception.
Viral Hashtag Challenges
- #IceBucketChallenge for ALS: This is the gold standard. It wasn't started by the ALS Association, but they embraced it, raising over $115 million and incredible global awareness.
- #InMyFeelingsChallenge by Drake: A viral dance challenge that showed how music and pop culture can drive massive hashtag engagement.
Advanced Instagram Hashtag Tips
Take your hashtag strategy to the next level with these pro tips.
Hashtags for Stories and Reels
Don't forget them here! You can add clickable hashtags to Stories (use the text tool or a hashtag sticker) and Reels. For Stories, you can also hide them by pinching them to make them tiny and then covering them with a GIF or sticker. Reels benefit hugely from trending audio and trending niche hashtags.
Shadowbanned Hashtags
If you suddenly see a dramatic drop in reach from hashtags, you might be shadowbanned. This means your content is hidden from anyone who doesn't already follow you. This can happen if you use broken or banned hashtags, use bots, or get reported. Use a tool to check if a tag is broken.
Using Location-Based Hashtags
Extremely powerful for local businesses or travelers. Use hashtags for your city (#LondonFood
, neighborhood, or specific venue. Also, always use the Instagram location tag in your post for an extra discovery boost.
Latest Instagram Hashtag Trends
- The Rise of Keyword Search: Instagram is pushing towards being a search engine. While hashtags are still critical, optimizing your caption and alt text with keywords is becoming increasingly important.
- Less is More (Sometimes): There's a growing trend towards using fewer, more hyper-relevant hashtags as captions become more focused on compelling copy.
- Authenticity Over Virality: The focus is shifting from chasing viral trends to using viral hashtags for Instagram reels to build genuine, micro-communities. Niche, specific hashtags are outperforming broad ones for engagement rates.
- Algorithm Updates: The algorithm now prioritizes engagement velocity (how quickly a post gets engagement). Using the right hashtags to get that initial burst of likes and comments is more crucial than ever to signal to the algorithm that your post is quality content worth promoting.
