How to achieve 1:1 personalization without much effort

  • How to achieve 1:1 personalization without much effort

Unless CEO Sander explains how using multiple audiences can lead to 1:1 personalization without much effort.

Hi, I am Sander, CEO at

The holy grail of website personalization is - of course - 1:1 personalization. This means that every single website visitor sees the content that is most relevant for him or her specifically. This maximizes the attention span of your visitors, improves conversion rates the most and provides the best user experience.

Until recently, this was pretty much impossible. But... Those days are over. Services like Unless provide you with the tools to achieve 1:1 personalization without much work, and even if you have a lot of traffic.

How does that work? Well, you need three things:

  1. Clear business goals;
  2. Granular customer segmentation;
  3. Parallel personalization of your website content.

Let me start with goals. You need a clear view of your business objectives. These goals can be positive (like a visitor buying your product) or negative (like a visitor returning a product). You need to define these goals in the Unless system to measure the success of your personalization. Very important.

Then, you need to define your audiences. Basically visitor categories. Take note: an audience is not the same as a “user persona”. Any website visitor typically fits multiple audiences.

You can define audiences by session context (like location, local weather or referrer), visitor background (name, address, industry - imported from your CRM system or so), or visitor achievements (like goals, visited pages and the topics a visitor read about).

Important: audience memberships may allow visitors to stay in an audience for a long time - so even for return visits or for later in your funnel, all the way to the goal that you defined.

Let's look at a simple example. If I look at myself, I could fit into these three audiences: people from Amsterdam, 40+ people who are shortsighted, and people interested in outdoor sports. But only these three audiences already allow for 8 different combinations and therefore 8 different user personas. And this adds up quickly! If I would come up with 20 audiences like that, there would be a million different permutations of people. With 33, you would have enough user personas to describe the entire world population uniquely - in theory. That's impressive, right?

Now, let's get back to the example. Let's say that I adjust my homepage for each of those three audiences. Unless will make sure that I can show a headline for audience 1, a background picture for audience 2 and some text changes for audience 3. These may or may not fire at the same time, depending on your audience membership combination. In my case, they will all fire.

So, using only 3 audiences, I can create a unique homepage for 8 different people. With 20 or more, I could serve unique content to millions of visitors, without that much work.

Mission accomplished, 1:1 personalization achieved!

Frequently asked questions

With audiences, you can group website visitors based on their similarities (e.g. "Returning Visitors"). You could also think of audiences as your user personas. Once you have an audience, you can connect it to one (or multiple) personalizations.

In Unless, a goal is a visitor action that leads to a tangible business result - like a sale, a download of a brochure, a newsletter signup, or a simple button click. You need to set goals to be able to see how your experiences are doing.

An experience is a piece of content (text, image, or HTML) that has been specifically altered to match the expectations of a certain audience. You can apply multiple experiences to a web page, for multiple audiences.
