How Hashtags Work in Instagram’s Algorithm

Instagram’s algorithm uses hashtags as content indexes to categorize and surface posts to relevant audiences. When you add a hashtag, your post becomes discoverable by users searching for or following that tag.

Key ranking considerations:

  • Relevance to post content
  • Engagement potential: likes, comments, shares
  • Content quality: clarity, resolution, captions
  • User interaction patterns: past behaviors and interests

A relevant set of hashtags can push your posts onto the Explore page or top hashtag feeds. Conversely, irrelevant or spammy tags may limit reach.

Research Trending Hashtags in Your Niche

To truly boost likes, focus on hashtags trending in your specific niche. Popular but relevant tags will target the right audience rather than random traffic.

Popular niches include:

  • Fashion: #OOTD, #StreetStyle, #SustainableFashion
  • Travel: #Wanderlust, #TravelGram, #AdventureCulture
  • Food: #Foodie, #RecipeOfTheDay, #HealthyEats
  • Fitness: #WorkoutMotivation, #FitLife, #GymFlow
Popular niches include: — best hashtags for instagram for likes

Research methods:

  • Use Instagram’s search bar and explore the “Tags” tab
  • Monitor trending posts in your niche
  • Follow and study industry influencers’ hashtag choices

Use Hashtag Tools to Find High-Engagement Tags

Specialized tools can identify the current most impactful hashtags.

Examples of tools:

  • Hashtagify – Tracks popularity, related hashtags, and patterns
  • RiteTag – Suggests hashtags based on real-time engagement data
  • All Hashtag – Generates and ranks hashtags from keywords

These resources speed up research, allowing you to capitalize on trends before saturation.

Mix High-, Medium-, and Low-Competition Hashtags

An effective list combines hashtags of different volumes to balance exposure and niche targeting.

Suggested distribution:

Type Post Volume Purpose
High-Volume 500k+ Broad exposure, rapid impressions
Medium-Volume 50k – 500k Better chance to trend within the tag
Low-Volume <50k High relevance, niche targeting

Aim for:

  • 3–5 high-volume hashtags
  • 5–7 medium-volume hashtags
  • 3–5 low-volume hashtags

---

Include Niche-Specific Hashtags

While generic hashtags can boost reach, niche-specific ones attract engaged users who care about your topic.

Example: A vegan recipe post should use #VeganRecipes and #PlantBasedEats rather than just #Foodie.

This targeted approach signals strong relevance to Instagram’s algorithm.

---

Avoid Banned or Spammy Hashtags

Instagram bans certain hashtags for misuse or spam. These tags can suppress visibility or cause a shadowban.

How to check:

  • Search the tag on Instagram; if “recent posts are hidden” appears, avoid it.
  • Use updated banned-hashtag lists from credible social media blogs.

---

Test Different Sets of Hashtags and Track Performance

Split testing hashtag combinations helps refine your strategy.

Track metrics such as:

  • Likes per post
  • Reach: unique accounts reached
  • Saves: user bookmarks

Instagram Insights and external analytics tools can compare results across multiple sets over time.

---

Leverage Location-Based Hashtags for Local Engagement

Geo-targeted hashtags work well for local businesses, events, or campaigns.

Examples:

  • #NYCFood
  • #LondonFashion
  • #SydneySunset

These tags connect you to area-specific audiences likely to engage or visit.

---

Keep Hashtags Relevant to the Content

Avoid mismatched ultra-popular tags. The algorithm penalizes irrelevant connections between hashtags and imagery or captions.

---

Analyze Competitor Posts for Effective Hashtag Ideas

Review competitors’ top posts to see what works:

  • Frequency of hashtags
  • Mix of generic vs niche-specific
  • Use of branded hashtags

Tools like KeywordTool.io for Instagram can ease this process.

Create Your Own Branded Hashtag

Branded hashtags consolidate your community’s posts into a searchable stream.

Examples:

  • #YourBrandNameStories
  • #LifeAtYourBrand

Invite followers to tag relevant content and engage under your unique hashtag.

---

Update Your Hashtag List Monthly

Algorithm behavior and trends shift fast. Refresh your list every month by:

  • Removing underperformers
  • Adding trending, relevant hashtags
  • Reinforcing branded hashtag promotion
