MARKETING B2B
IN SHORT

A buyer persona is the semi-fictional representation of the ideal customer, built on qualitative and quantitative data, not a simple description of the audience.
They are central to strategic marketing: they guide product development, marketing, sales and support, and help attract valuable leads.
They are built by collecting demographic, professional and psychographic data, challenges, channels and the purchase process, always to be adapted to the specific case.
The data comes from real customers, interviews and questionnaires, the sales team, analytics and market research: the approach is data-driven.

In the stories section of our site there are many articles dedicated to marketing, almost always with at least one reference to buyer personas. This concept is definitely one of the foundations of any strategic marketing activity, but it is not always easy to grasp.

In this guide you will find the answer to the most popular questions on the topic: what buyer personas are, why they are used and how they are built.

Buyer personas: the definition

A buyer persona is an abstract representation of an ideal customer, built from qualitative and quantitative data. These can come from the analysis of real customers and from market research.

This semi-fictional representation, moreover, provides not a mere description of the potential audience, but also a set of information useful to define the marketing and sales strategy and to create new products.

Why are buyer personas important?

When you combine the Buyer Profile with Buying Insights, you will have clear guidance for the decisions you need to make to win their business.

Nowadays, there is no marketing expert who does not recognise the key role of buyer personas, not only for go-to-market, but also for companies that are already established.

In fact, they provide information useful to increase the chance of attracting high-value potential buyers, generate relevant leads and ease the conversion and loyalty process.

Product developmentBecause they reveal what the audience needs from the service/product, setting the priorities to consider.
Marketing strategies and tacticsFrom keyword research to the choices regarding content positioning.
The sales processIdentifying the weak points and challenges that potential customers face.
Customer supportAllowing you to anticipate the most common problems and challenges that customers may face.

A key element in strategic marketing

In defining a marketing strategy, the information drawn from the definition of buyer personas is used to personalise communication and direct efforts towards the appropriate channels.

Thanks to this awareness, it is possible to create a highly targeted and personalised branding and buyer experience.

This happens, for example, by using the data drawn from buyer personas to better segment customers. Or, to develop a valuable branding experience for a specific group of people, through targeted messages, publishing relevant content on selected platforms and tailored offers.

The same care is useful in the search for qualitative leads too: where does a potential buyer look for information? What kind of communication do they prefer? What challenges do they face? All the answers to these questions are essential for an effective sales process!

How do you create buyer personas?

To create effective and useful buyer personas, it is essential to keep in mind which information is needed to form a good idea of the ideal customer.

After choosing the name of a fictional buyer and assigning them a photo, you need to collect the necessary data. Below we have included a list of the most important ones, which does not claim to be exhaustive. In fact, it must be modified to fit the specific case.

01

Demographic dataThese are certainly the easiest to collect! Among them we find: age, gender, annual income, geo-location (where they live), family status (especially for B2C) and level of education.
02

Professional statusBoth B2B and B2C companies must take the professional factor into account. In fact, this helps to understand who makes decisions, who actually uses the product or service, the type of challenges faced and much more. To start, it is good practice to investigate the job title and level of the position and the industry.
03

PsychographicsThis term refers to the need to identify customers’ values, opinions and goals, in order to create a truly effective buyer persona. In fact, most consumers prefer to buy from companies with which they share values and viewpoints. This section includes both professional and personal goals and values and beliefs.
04

Pain points and challengesThis information is probably among the most important for developers, creatives, marketing experts and salespeople. In fact, only by knowing and understanding the problems and obstacles of potential customers can you develop a product or service able to offer not just a solution, but the best one for the ideal buyer. Moreover, understanding what buyer personas focus on helps to develop truly effective communication, both in marketing and in the sales phase!
05

Channels and information sources

  • Where does the buyer persona look for information on topic X?
  • Which voices do they listen to (and consider trustworthy) to form an idea of a product or service?
  • Which social networks do they use?
  • Do they attend industry festivals or trade fairs?
  • On which platforms do they look for solutions?
  • This information helps to direct marketing efforts in the right direction, both in B2B and B2C!
06

Purchase processTo build the best buyer personas, it is important to identify how they make purchase decisions. Which path do they follow and which triggers do they value positively? How often do they buy the product or service? What role do they have in the decision-making power? Which factors prevent them from completing the purchase? In this research phase, the initial and final stages should not be underestimated. For example, it is useful to know information such as the preferred payment methods.

Data research

Once you have established which information is needed, it is time to discover how and where to find it. This is possible by collecting data from existing customers, through interviews, forms and questionnaires, or from reports produced by the sales team.

Then, you can gather information to build buyer personas from company data and digital data. Google Analytics is a source of valuable information about existing and potential customers, especially when combined with other management tools and analytics platforms, as well as social media (such as Facebook Audience Insights).

Finally, you can gather information from market research and by observing the websites of competitors with the same ideal customer profile.

CONCLUSIONS

Building your own buyer personas is essential to develop, for example, the most effective marketing tactics, to establish buyer’s journeys that work, to produce truly useful products and to ease sales and quality lead generation.

That is why defining buyer personas with a data-driven approach is one of the essential steps to establish decisions and investments.
