Instagram SEO: How to Get Found in Search and Explore in 2026

Instagram is a search engine. Over 50% of users now use Instagram's search bar to find accounts, products, and information. If your content is not optimised for search, you are invisible to the people actively looking for what you offer.

We have tested Instagram SEO strategies across 32,000+ brands. The accounts that treat Instagram like a search engine consistently outperform those that rely solely on hashtags and the home feed. Here is exactly how to optimise your account.

What Instagram SEO actually means

Instagram SEO is the practice of optimising your profile, content, and metadata so that Instagram's search and recommendation systems show your content to relevant users. It works across several discovery surfaces:

• Instagram Search. When someone types a keyword, Instagram returns accounts, hashtags, places, and Reels.
• Explore page. Instagram uses content signals to recommend posts to users who do not follow you.
• Suggested accounts. The "Suggested for you" section recommends accounts based on content relevance.
• Reels feed. Instagram's Reels algorithm uses text, audio, and visual signals to categorise and distribute content.

Every one of these surfaces uses keyword matching and content categorisation. That is SEO.

Optimise your profile first

Your profile is the most important piece of Instagram SEO. It is the first thing the algorithm reads when categorising your account.

Username. Include a primary keyword if possible. "@londonfitnesscoach" ranks better for "fitness coach London" than "@sarah_jane_92". If your brand name is established, keep it, but add keywords to your display name.

Display name. This is searchable. Use it strategically. Instead of just "Sarah Jones", try "Sarah Jones | Fitness Coach for Busy Mums". You get 30 characters here, so make every word count.

Bio. Instagram scans your bio for keywords when deciding who to show your profile to. Include your niche keywords naturally. "Helping busy professionals build strength and confidence through personalised training programmes" is far better than "Living my best life" for search discovery.

Category. Choose the most specific Instagram business category available. "Fitness Trainer" is better than "Entrepreneur". This category label is a direct ranking signal.

Caption keywords are the new hashtags

In 2026, keywords in your captions matter more than hashtags for discovery. Instagram's natural language processing reads your caption text and uses it to understand what your content is about.

Put keywords in the first two lines. Instagram gives more weight to text that appears early in the caption. Start with the topic, not with a hook that avoids the subject.

Use natural language, not keyword stuffing. Write for humans first, but include relevant terms. "5 strength training exercises for beginners who want to build muscle at home" naturally includes multiple searchable terms without feeling forced.

Include long-tail phrases. "How to grow on Instagram as a coach" is a specific query that real people search for. Work these conversational phrases into your captions.

Add secondary keywords throughout. If your post is about meal prep, include related terms like "weekly food prep", "healthy lunches", "batch cooking", and "nutrition tips" throughout the caption.

Hashtag strategy for SEO in 2026

Hashtags still work, but their role has changed. They are now one signal among many, not the primary discovery mechanism.

Use 5-10 targeted hashtags. The era of 30 hashtags is over. Instagram's own guidance suggests fewer, more relevant hashtags perform better than volume.

Mix sizes. Use 2-3 large hashtags (1M+ posts), 3-4 medium hashtags (100K-1M posts), and 2-3 small hashtags (under 100K posts). Small hashtags give you the best chance of ranking near the top.

Match hashtags to content. Every hashtag should describe exactly what the post is about. Generic tags like #instagood do nothing for SEO. Specific tags like #mealpreptips or #coachingbusiness attract the right people.

Create a branded hashtag. Encourage your community to use a unique hashtag. This builds a content library that reinforces your account's authority in your niche.

Alt text and accessibility as ranking signals

Instagram allows you to add alt text to every image post. Most people skip this. That is a missed opportunity.

Write descriptive alt text manually. Instagram auto-generates alt text, but it is generic. Write your own using keywords that describe what is in the image and what the content is about.

Be specific and natural. "Personal trainer demonstrating a kettlebell deadlift in a home gym setup" is far better than "workout photo" for both accessibility and search ranking.

Include your niche terms. Alt text is another place where Instagram learns what your content is about. Use it consistently to reinforce your niche signals.

Reels SEO: Text, audio, and visual signals

Reels have their own SEO considerations. Instagram uses multiple signals to categorise and recommend Reels.

On-screen text. Any text overlaid on your Reel is readable by Instagram's systems. Include keywords in your text overlays, especially in the opening frames.

Audio. If you are speaking, Instagram transcribes your audio. Say your keywords out loud. "Today I'm showing you how to grow your Instagram as a real estate agent" directly feeds the algorithm the terms it needs.

Caption keywords. Same rules as photo posts. Front-load your Reel captions with relevant keywords.

Trending audio. Using popular sounds gives a distribution boost, but do not sacrifice relevance for trends. A trending sound that does not match your niche confuses the algorithm.

Building topical authority on Instagram

The most powerful Instagram SEO strategy is topical authority. When you consistently post about the same subjects, Instagram recognises your account as an expert in that area and shows your content more frequently to relevant audiences.

Post about your core topics repeatedly. If you are a skincare brand, every post should relate to skincare in some way. Occasional off-topic posts are fine, but 80% or more of your content should reinforce your niche.

Create content series. Weekly series like "Monday Myths" or "Friday Q&A" build predictable content patterns that the algorithm can categorise and recommend.

Interlink your content. Reference previous posts in your captions. Use carousel posts to cover subtopics in depth. The more interconnected your content, the stronger your topical authority signal.

Measuring your Instagram SEO performance

Track these metrics to see if your SEO efforts are working:

• Reach from Explore. Check Instagram Insights for how much of your reach comes from the Explore page and search.
• Profile visits from non-followers. An increase means more people are discovering you through search.
• Follower growth rate. Organic follower growth accelerates when your SEO is working because you are appearing in more discovery surfaces.
• Keyword ranking position. Search for your target keywords on Instagram and note where your account or content appears.

If your Explore reach is low, your content is not being categorised well. Revisit your keywords, captions, and content consistency.

To give your SEO-optimised content the best chance of ranking, pair it with AI Instagram Engagement. Early engagement signals tell Instagram that your content is worth recommending, which amplifies the SEO work you have already done.

For accounts ready to accelerate their search visibility and grow with targeted followers in their niche, the Follower Growth Engine builds the audience base that reinforces your topical authority with every new follower.
