In the dynamic world of Instagram, where millions of posts are shared every day, standing out can feel like an uphill battle. One of the most powerful yet misunderstood tools at your disposal is the hashtag. Hashtags not only categorize your content but also increase discoverability, connect you with your target audience, and amplify engagement.
But here’s the big question:
👉 How many hashtags should you actually use on Instagram in 2025 to maximize reach without looking spammy?
This comprehensive guide will answer that question based on the latest industry research, expert opinions, and real-world best practices. We’ll deep dive into everything from Instagram’s official guidelines to pro tips and common mistakes, ensuring you have a clear, actionable hashtag strategy.
Why Are Hashtags Important on Instagram?
What Are Hashtags?
Hashtags are words or phrases preceded by the “#” symbol (e.g., #TravelPhotography) that serve as metadata tags. They help Instagram organize content into categories and enable users to discover posts relevant to their interests. When someone searches for or follows a hashtag, they see content from various users tagged with that specific keyword.
How Do Hashtags Work?
Instagram’s algorithm uses hashtags to index and categorize content. This allows your posts to appear in the Explore page and hashtag feeds, helping your content reach beyond your current followers. Strategically using the right hashtags enhances visibility, increases engagement, and drives follower growth.

The Impact of Hashtags on Engagement
Multiple studies show that posts with relevant hashtags experience higher engagement rates than those without. Hashtags:
- Improve reach by making posts discoverable by a broader audience.
- Help connect with niche communities.
- Facilitate user-generated content discovery.
Instagram’s Official Hashtag Guidelines
Instagram’s own documentation clarifies the technical side of hashtag use:
- Maximum Hashtags per Post: You can add up to 30 hashtags per feed post or Reel, and up to 10 hashtags per Story.
- Placement: Hashtags can be added in the post caption or as a comment. Both approaches work, but placing them in the caption guarantees immediate indexing.
- Banned Hashtags: Instagram maintains a list of banned or restricted hashtags that offer no reach benefit and may penalize your account. Examples include #like4like and #followback.
Important Tip:
Use only relevant hashtags that accurately reflect your post content. Avoid stuffing irrelevant or overly generic tags that don’t align with your niche.

What Studies and Experts Say About Hashtag Count
Let’s look at the data.
1. Later Study (2022)
A comprehensive study from Later analyzed over 12 million Instagram posts and found that posts using 5–10 relevant hashtags consistently saw the highest engagement rates.
2. HubSpot Study
HubSpot recommends using around 9 hashtags per post for optimal engagement without triggering spam filters.
3. Social Insider Data
Social Insider reported that overusing hashtags (more than 15) doesn’t significantly improve engagement and may lead to reduced performance due to Instagram’s spam detection systems.
Key Insight:
A focused approach of using 5 to 10 well-researched and relevant hashtags provides the best balance of reach, engagement, and authenticity in 2025.
Best Practices for Hashtag Usage
1. Prioritize Relevance Over Quantity
Instead of filling your post with 30 hashtags, focus on selecting the most relevant ones that speak directly to your audience and the content.
Example:
For a travel post about Iceland’s waterfalls, use:#IcelandTravel #WaterfallLovers #TravelPhotography #NatureLovers #ExploreIceland
2. Mix Different Types of Hashtags
- Trending Hashtags: Broader reach, e.g., #Travel, #Photography
- Niche Hashtags: Smaller but more targeted, e.g., #IcelandWaterfalls, #NordicNature
- Branded Hashtags: Unique to your brand, e.g., #YourBrandTravels
3. Placement of Hashtags
- In the Caption: Immediate indexing and visibility.
- In Comments: Keeps the caption clean but delays indexing by Instagram.
Both methods are valid, though placing hashtags in the caption provides faster results.

Common banned hashtags include #FollowMe, #LikeForLike, or #GainFollowers.
Using these will hurt your post visibility.

Track:
- Engagement per hashtag

- Follower growth from hashtag reach
Adjust your strategy accordingly.
4. Update Your Hashtag Strategy Regularly
Instagram trends change fast. Reevaluate your hashtag list every 3–6 months.
Common Hashtag Mistakes to Avoid
- Using Irrelevant Hashtags
Example mistake: Posting a fitness image with hashtags like #Fashion or #Travel.
This leads to low engagement and confused audience targeting. - Using Banned Hashtags
Banned hashtags are often temporarily or permanently restricted due to misuse or spam.
Examples: #Snapchat, #Adulting, #FollowForFollow - Overstuffing Hashtags
Using the full 30 when 5–10 relevant ones perform better.
It looks unprofessional and may cause algorithm penalties. - Copy-Pasting the Same Hashtags Repeatedly
Instagram favors fresh, relevant content. Repeating the same hashtags reduces discoverability.

In 2025, the ideal hashtag strategy focuses on quality over quantity.
- Use 5 to 10 highly relevant hashtags per feed post.
- Prioritize a good mix of trending, niche, and branded hashtags.
- Avoid banned or irrelevant hashtags.
- Monitor your strategy using Instagram Insights and adjust regularly.
By mastering hashtags the right way, you’ll significantly boost your Instagram growth, engagement, and brand presence.
