Instagram is no longer just a feed of friends’ photos. People use its search bar to find restaurants, hairdressers, recipes, workouts, wedding photographers and products. If your account does not show up for those searches, you are relying entirely on existing followers and luck.
Instagram SEO is the practice of optimising your profile and posts so they appear in Instagram search, on Explore and in Reels recommendations – and, since 2025, in Google search results too. The good news is that Instagram has explained a lot about how its systems work, so you do not have to guess.
In this guide you will learn how Instagram search ranks results, a step-by-step optimisation process, the 2026 rules on hashtags and originality, how Instagram posts reach Google, and the mistakes that quietly limit reach.
Key Takeaways
- Instagram matches search text against usernames, profile names, bios, captions, hashtags and places.
- Put keywords and hashtags in the caption, not the comments – Instagram says this is how posts get found in search.
- Posts and Reels are limited to five hashtags, so choose specific, relevant ones.
- Original content gets recommended; reposts and watermarked videos can be excluded or replaced by the original.
- Public posts from professional accounts can appear in Google and Bing, controlled by a privacy setting.
How Instagram search works
Instagram describes three main groups of signals for search results.
- Your search text. What the person types is matched against relevant usernames, bios, captions, hashtags and places.
- Your activity. Accounts and hashtags someone follows or visits, and posts they have engaged with, tend to rank higher for them.
- Popularity. When there are many matches, Instagram considers signals such as clicks, likes, shares and follows for an account, hashtag or place.
“For a post to be found in Search, put keywords and hashtags in the caption, not the comments.”

Search is only one discovery surface. Instagram’s ranking explainer says Feed, Stories, Explore and Reels each use their own signals. Explore and Reels mostly show content from accounts people do not follow, so they are where new audiences find you. For Reels, Instagram says it predicts actions such as whether someone will reshare a reel, watch it to the end, like it or visit the audio page.
Where your keywords should go
| Element | Searchable? | Best practice | Example |
|---|---|---|---|
| Username (handle) | Yes | Brand name, short and easy to spell | @bloomflowersleeds |
| Display (profile) name | Yes | Brand plus main keyword | Bloom | Leeds Florist |
| Bio | Yes | What you do, who for, where | Wedding and event flowers in Leeds. Same-day delivery. |
| Caption | Yes | Main keyword in the first line, natural sentences | “Spring wedding bouquet ideas with seasonal British flowers…” |
| Hashtags | Yes | Up to five specific tags in the caption | #leedswedding #weddingflowers |
| Location tag | Yes (places) | Tag the real location | Leeds, United Kingdom |
| Alt text | Accessibility aid | Describe the image accurately | “Bridal bouquet of white peonies and eucalyptus” |
| Comments | Not for discovery | Use for conversation, not keywords | – |
How to optimise your Instagram account: step by step
- Switch to a professional account. Business or creator accounts give you insights, contact buttons and eligibility to have public posts shown in search engines.
- Research keywords. Type your topics into Instagram search and note the suggested accounts, tags and keywords. Reuse findings from your website keyword research and our wider guide to social media SEO.
- Optimise your display name. Add your main keyword next to your brand. Instagram suggests choosing a name related to your content, including names people know you by.
- Rewrite your bio. Add keywords about who you are and what you offer. Instagram specifically notes that location-based accounts, such as small businesses, can include their location to help local people find them. This supports your wider local SEO.
- Front-load captions. Start with a sentence that clearly names the topic, then add value: steps, tips or the story behind the post.
- Choose up to five hashtags. Mix a topic tag, a niche tag and, where relevant, a location or branded tag.
- Add alt text. In the advanced settings when posting, write a short, accurate description. The principles are the same as for alt text on your website and image SEO.
- Make Reels search-friendly. Say the topic in the first seconds, add on-screen text and enable captions. Choose a clear cover image.
- Post original content. Film your own footage, avoid watermarks from other apps and credit collaborators properly.
- Engage and review. Reply to comments quickly, check insights for discovery sources, and use your own data to find the best time to post on Instagram.
Hashtags in 2026: fewer and more specific
In December 2025 Instagram announced, via its @creators account, that posts and Reels would be limited to five hashtags after a year of testing. Instagram’s advice accompanying the change was that a few targeted hashtags work better than many generic ones, and that tags such as #reels or #explore do not help content appear in Explore.
- Use hashtags to describe the topic, not to chase reach.
- Prefer niche tags your audience actually browses (#veganbakinguk) over huge generic tags (#food).
- Create one branded hashtag for campaigns or user-generated content.
- Do not repeat the same block of tags on every post; match tags to each post’s content.
Originality and recommendations
Instagram’s creator guidance sets out clear rules. Eligible original reels are first shown to a small audience and expanded if they perform well. When identical copies of content exist, Instagram says it will only recommend the original. Accounts that repeatedly post other people’s content – which Instagram defines as 10 or more times in the last 30 days – without creating or materially enhancing it are not shown in recommendations while above that threshold.
Visible watermarks also affect eligibility. If you film for TikTok and cross-post to Instagram, export a clean version without the watermark. You can check Account Status in your settings to see whether any content is ineligible for recommendations, remove it and appeal if you think a mistake was made.
Instagram posts in Google search
Since 10 July 2025, public photos and videos from professional accounts owned by adults can be shown by search engines such as Google and Bing. The control sits in your privacy settings as “Allow public photos and videos to appear in search engine results”. Personal and private accounts are not affected.
This makes captions doubly important: a clear, descriptive first line helps Instagram search and gives Google text to understand. Treat important posts – service explanations, product launches, local events – as small landing pages, and support them with repurposed content on your website.
Measuring Instagram SEO
| Metric | What it tells you | Where to find it |
|---|---|---|
| Reach from non-followers | How well you are being discovered | Post and Reel insights |
| Profile visits | Whether discovery leads to interest | Account insights |
| Follows from post | Whether content converts viewers into followers | Post insights |
| Saves and shares | Content value; signals Instagram predicts for Explore | Post insights |
| Link clicks and website sessions | Business impact | Insights plus GA4 with UTM parameters |
Common mistakes
- Hiding keywords in comments. Instagram says captions, not comments, are what search uses.
- Generic hashtags. #love and #instagood describe nothing and waste one of your five slots.
- A clever bio that says nothing. “Living the dream ✨” gives search no clue what you do.
- Cross-posting watermarked videos. These can be excluded from recommendations.
- Aggregating others’ content. Reposting without permission or meaningful changes can remove you from recommendations.
- Inconsistent posting. Discovery compounds over time; long gaps reset momentum. A social media calendar helps.

Frequently Asked Questions
How many hashtags should I use on Instagram in 2026?
Instagram now limits posts and Reels to five hashtags. Choose a handful of specific tags that describe the content and audience, and avoid generic ones such as #reels or #explore, which Instagram has said do not help content appear in Explore.
Do keywords in Instagram comments help SEO?
No. Instagram’s own guidance is to put keywords and hashtags in the caption, not the comments, if you want a post to be found in search.
Does changing my Instagram name affect search?
Your username and display name are both matched against search text, so including a descriptive keyword in your display name can help people find you. Keep your handle stable and recognisable, as frequent changes can confuse existing followers.
Will my Instagram posts appear in Google?
If you have a public professional account and are over 18, your public photos and videos can be shown by search engines, controlled by the setting “Allow public photos and videos to appear in search engine results”. Personal and private accounts are not included.
Why are my Reels not being recommended?
Check Account Status in your settings to see whether any content is ineligible for recommendations. Common causes include watermarks from other apps, reposting content you did not create, and content that goes against Instagram’s recommendation guidelines.
Conclusion
Instagram SEO is not a trick. It is clear labelling plus original content: a descriptive name and bio, captions that state the topic up front, a few precise hashtags, accurate alt text and Reels people want to finish. Do that consistently and Instagram – and now Google – will have every reason to show your posts to new people.
