Target group, customer group and personas – the difference and how to use them

"Who is your target group?" is one of the first questions in every web and marketing project. The problem is that the answer often mixes up three different terms – target group, customer group and persona – that drive completely different decisions. Here is the difference, and why it matters when you write content and build a website.

What is a target group?

A target group is the broad group of people you want to reach with your message, defined by shared characteristics – demographics (age, gender, location), needs, behaviour or industry. For example: "small and medium-sized e-commerce companies in Sweden that want to grow their organic traffic". So the target group is a slice of the market – not an individual but a segment you aim at. It mainly determines where and how you show up: which channels, which overall tone, which market. If you want to map your target group systematically, we go through it step by step in our guide to target audience analysis.

What is a customer group – and how does it differ from a target group?

Customer group is the vaguest of the three terms, because it is used in two ways. Sometimes it is simply a synonym for target group. Used more precisely, a customer group is a segment of your actual or potential customers – grouped by something meaningful, such as buying behaviour, order value or industry. The difference is that the target group is who you want to reach, while the customer group is often based on who actually buys – or on your most important buyers. It is worth spelling out that distinction internally, so that everyone means the same thing.

What is a persona?

A persona (or buyer persona) is a fictional but data-based representative of a target group or customer group. Unlike the target group, the persona is concrete, with a name, a role, goals, challenges and objections. The point is not to invent a character but to distil patterns from real data into something a whole team can write and design for. A good persona answers the question: who are we writing this for, and what do they need to know to feel confident?

How do you create a persona?

A persona works best with data behind it. Build it from:

• Customer data and CRM – who actually buys, and what do they have in common?
• Interviews and conversations – with customers, and with sales or support staff who talk to them every day.
• Analytics and search behaviour – how do visitors behave on the website, and what do they search for?

Do not stop at demographics. The most important parts of a persona are goals, motivations and objections – they are what determine what you should actually write. Want concrete interview questions and a template to fill in? Our guide to creating personas goes through the whole process step by step.

How target groups and personas steer web, content and SEO decisions

This is where the practical value lies – and what most articles skip. When you know who you are writing for, you can decide:

• Search intent – which question and which stage of the buying journey a page should address, not just which keyword has the highest volume.
• Tone of voice – should an H1 speak to the technical user or to the decision-maker who pays?
• Choice of content and CTA – which objections have to be answered, and which next step it makes sense to point to.
• Page structure – what has to be visible at the top for this particular persona.

A web agency that does not know who the page is for cannot make any of those decisions on a sound basis – it is just guessing. That is why good content and SEO work always starts with the target group and the persona, together with keyword research.

Personas and AEO – understand the questions customers ask AI

Instead of typing two words into Google, more and more people put whole, context-rich questions to AI assistants such as ChatGPT, Gemini and Perplexity – and to Google's AI Overviews. The questions sound more like a conversation: "which website platform suits a small B2B company that already uses HubSpot?" rather than "best cms". Being visible and cited in those answers is what AEO is all about – and this is where the persona becomes one of your sharpest tools.

A well-built persona tells you exactly which questions your buyers actually ask, in which context and with which objections. They are the same questions they now put to an AI. If you know the persona's goals, situation and hesitations, you can write content that answers exactly those context-rich questions clearly and concretely – and that makes you the source the AI picks up.

This is also where the different parts fit together: business understanding decides which questions are worth answering, and the copy makes the answers citable. Persona work is the bridge between traditional search intent and AEO – from "which words do they search for?" to "which questions do they ask, and what do they need to hear to choose us?"

Common mistakes

• A persona based on gut feeling. An invented character without a data basis only confirms your own assumptions.
• Personas that are never updated. Target groups and behaviours change – a persona from 2021 can be misleading today.
• Too many personas. Three sharp personas are more useful than ten vague ones. Start with the most important ones.

Target group, customer group and persona are working tools, not bureaucracy. Their value lies in what they shape: where you show up, what you write and how you build the website around the people you actually want to reach.
