Most brand owners are still treating Instagram like a broadcast channel. Post something, hope the algorithm likes it, watch the reach fluctuate.
There’s a whole layer of Instagram that most people are completely ignoring and it’s one of the most consistent ways to bring new, relevant people to your profile every single week without spending a penny on ads.
So what is this magic trick called?
It’s called Instagram SEO, and if you’re not doing it, you’re almost certainly invisible to people who are actively looking for exactly what you offer.
What Is Instagram SEO?
Instagram SEO is the practice of optimising your profile, content and captions so that your account appears in search results, both inside Instagram and increasingly in Google.
When someone types “Liverpool personal trainer” or “sustainable skincare brand” or “interior designer London” into the Instagram search bar, the platform runs its own algorithm to decide which accounts and posts to surface.
That algorithm is looking for signals, these are keywords in your bio, your username, your captions, your alt text, and your hashtags, in order to work out what you’re about and who you’re relevant to.
Get those signals right, and Instagram starts putting you in front of people who are already looking. Miss them, and you’re relying entirely on luck and virality to grow.
It’s not complicated, but it does require some intention.
How Instagram SEO Differs From Google SEO (And How It's the Same…)
If you’ve heard of Google SEO before, a lot of the core logic carries over, but there are some important differences worth understanding.
Where they’re the same:
Both platforms use keywords to understand what your content is about. Both reward consistency and relevance. Both prioritise accounts and pages that clearly signal who they help and what they do, and both are increasingly being used as the first point of discovery, not just a place people go once they already know your name.
Where they differ:
Google SEO is largely built on your website. It rewards long-form content, backlinks, technical site structure, domain authority and page speed. It’s a slower burn, but when it works it compounds over a long time.
Instagram SEO works differently. It lives inside the app.
Your signals are your bio, your name field, your captions, your hashtags and your engagement. There are no backlinks (yet). There’s no domain authority (yet). But there is velocity, Instagram can surface a post within hours of it going live if the signals are strong. That’s something Google almost never does.
The other key difference is intent. When someone searches on Google, they’re usually in research or buying mode.
When someone searches on Instagram, they’re often in discovery mode. They’re not always ready to buy right now, but they’re warm, interested and looking. That’s a genuinely valuable place to be visible.
Why This Matters for Both Online and Local Brands
This is where it gets interesting, because Instagram SEO works very differently depending on whether you’re an online brand or a local one.
For online brands, Instagram SEO is about niche relevance.
If you sell eco-friendly home products, plant-based supplements, or independent fashion, you want to be appearing when people search the interests, aesthetics and problems connected to your product category.
The goal is to become a fixture in your niche, the account people keep finding when they search around your space. Over time, that builds brand familiarity, and brand familiarity builds trust.
And trust is what eventually converts a follower into a customer.
For local brands, Instagram SEO is even more powerful in some ways, because local search on Instagram is still massively underused by most businesses.
If you’re a salon in Manchester, a coffee shop in Bristol, a gym in Liverpool, or a clinic in Leeds, the vast majority of your competitors are not optimising their Instagram for local search.
That means the bar to appear is low. A well-optimised bio, location-tagged posts and locally-relevant captions can put you in front of people in your area who are actively looking for what you offer… right now, for free.
Think about how many people open Instagram in a new city and search for coffee shops, gyms, restaurants or services near them. If your account is properly optimised, you show up. If it’s not, you don’t. That’s the whole game.
How to Update Your Instagram Bio for Search
Your bio is the single most important piece of Instagram SEO real estate you have. Most brands waste it completely by writing something vague, clever or personality-led that tells the algorithm nothing useful.
Here’s how to do it properly.
Your Name Field (not your username)
This is the most important field on your entire profile for SEO. It’s the bold text that sits above your bio. Most people put their brand name here and nothing else. That’s a missed opportunity.
Instagram’s algorithm reads your name field as a primary keyword signal. So instead of just your brand name, include your key service or category alongside it.
Examples:
- Instead of: Glow Studio
- Try: Glow Studio | Skin & Aesthetics Manchester
- Instead of: Tara Fitness
- Try: Tara Fitness | Online Coach for Women
You have 30 characters in this field. Use every single one of them.
Your Username
If your username hasn’t been taken in a keyword-rich form, it’s worth considering. Something like @liverpoolpersonaltrainer or @sustainableskincareco gives you an extra keyword signal. That said, brand consistency matters too, don’t sacrifice a strong brand name for keywords. But if you’re starting out, it’s worth thinking about.
Your Bio Text
Your bio should answer three questions very clearly: who you are, who you help, and what you do. Avoid vague phrases like “helping people live their best life”, they mean nothing to the algorithm and not much more to a new visitor.
Use plain language that mirrors how your target audience would actually search.
Structure to follow:
- Line 1: What you do and who for
- Line 2: Your unique angle, result or method
- Line 3: Social proof or location signal (especially for local brands)
- Line 4: Call to action with a link
Example for a local physio:
Sports & remedial massage in Liverpool

Location
If you’re a local business, make sure your location is set. Go to Edit Profile and add your city or area. This helps Instagram surface you in local search results.
Category
In your profile settings, you can set a business category. Use it. It gives Instagram additional context about what type of business you are and helps match you to relevant searches.
The Instagram SEO Caption Cheatsheet
Your captions are your ongoing keyword engine. Every caption is an opportunity to signal relevance to both Instagram’s algorithm and the people searching in your niche. Here’s how to write them with SEO intent built in.
Lead With Your Keyword
The first 125 characters of your caption are shown before the “more” cut-off. This is your prime real estate. Lead with a clear, keyword-rich opening line that reflects what the post is about and who it’s for.
Formula: [What this post is] + [who it helps] + [the result or hook]
Example: “The reason your skin isn’t clearing up, even when you’re doing everything right. If you’re based in Manchester and struggling with adult acne…”
Use Location Language Naturally (For Local Brands)
Don’t just hashtag your location, mention it in the caption copy itself. Instagram reads caption text, not just hashtags.
Example: “If you’re a business owner in Liverpool looking to grow your brand online, this one’s for you.”
Write for Your Audience’s Search Behaviour
Think about how your ideal customer describes their own problem or desire. Use their language, not industry language.
Instead of this | Write this |
“Hyaluronic acid formulations” | “Skincare for dry, dehydrated skin” |
“Resistance-based periodisation” | “Strength training for beginners” |
“Full-stack digital solutions” | “Marketing agency for small businesses” |
“Holistic modalities” | “Natural remedies for anxiety and stress” |
Quick Caption Audit: Ask These Questions Before You Post
- Does the first line include a keyword your audience would actually search?
- Have I mentioned a location at least once if I’m a local brand?
- Am I using language my audience uses, or language I use?
- Have I included a clear CTA?
- Are my hashtags specific enough to actually reach the right people?
Your Search Strategy
Instagram SEO is about making it easier for the right people to find you and making it completely clear, the moment they land on your profile, that you’re exactly what they were looking for.
Most brands aren’t doing this… and those that are aren’t doing it very well. Which means if you start now, you’re already ahead.
