The personalisation playbook: A guide to data-driven personalisation at scale

As beneficial as business growth is, sometimes growing businesses lose the critical ability to make every customer experience feel personal, resulting in lost revenues and the perception of a business that is out of touch with the needs of its customers. In the past, this may have motivated organisations to limit their growth to retain strong branding and customer relationships. Today, however, modern marketing technology provides a way to scale businesses to their full potential while still maintaining a close, personal customer experience with every customer. This is what we call personalisation at scale.

Personalisation at scale

The road to personalisation at scale starts with envisioning a personalisation roadmap. What current state personalisation technology exists in your firm? Are you committed to creating positive, personalised experiences through trust and dialogue with customers? Answers to questions like these will help guide your firm to the right tools, strategies, and vendors to create your ideal customer experience—one where data-driven decision-making can allow every customer to be met with the right message, at the right place, at the right time, no matter how much your business scales. Accomplishing this requires thoughtful orchestration of a MarTech architecture like the one below:

To translate the graphic above into straightforward terms, personalisation is all about gathering the right information from your customers, using it to learn more about who they are and what they care about, delivering the right content and communications at the right time based on what you now know about them, and finally - using what you've learned as an organisation to do it all it over again, but with more marketing precision each time.

Delivering such a customer experience is possible through careful manual analysis and planning for small customer bases, but many of today’s businesses grow too quickly and reach too broad of an audience to rely on headcount-driven marketing tasks. This is where a personalisation technology stack can be a difference maker in your business.

Ideally, building a personalisation technology stack allows for the automation of the three most involved tasks in the reference architecture above: sourcing inputs, making decisions, and producing outputs. If technology can handle these tasks, supporting marketing teams are then freed up to analyse past and current campaign results and make well-informed decisions about future ones. We’ll spend most of this blog focusing on the specific components of the personalisation technology stack, but there is no doubt that dynamic marketing decision-makers are still essential to the success of any marketing organisation, regardless of the technology available.

Segmenting the tasks that are managed by the personalisation technology stack from the functions requiring human input and decision-making allows us to define two distinct categories in the reference architecture

Now, let’s narrow our focus to the components of the personalisation technology stack. An effective personalisation technology stack should include three primary components:

  1. A data ingestion and unification stack for streamlined data inputs

  2. A synchronised decisioning engine

  3. A targeted omni-channel output layer

Throughout the rest of this blog post, we’ll walk through the essential role that each of these three components plays in creating a personalised customer experience. Let’s break down each phase of this framework.

The personalisation framework begins with tools to manage inputs – collecting data from across the web and unifying all sources into a single data stream.

With data coming from thousands of places and governing bodies tightening data regulations, it can be intimidating to collect customer data at scale. Thankfully, sophisticated data ingestion and consent management tools have adapted to meet this challenge, making it easier than ever to gather valuable customer first-party data in the post-third-party cookie era. These tools then unify the data to create a single stream of data input for your decisioning engine. This means millions of data points can be filtered to narrow down the inputs your company needs most.

Content management and data decisioning tools form the “engine” of a personalisation stack, transforming raw data inputs into actionable customer insights and managing dynamic content for later use.

The heartbeat of an effective personalisation process is the decisioning engine. At a high level, decisioning engines transform raw data inputs into readily available customer profiles and then recommend next-best actions and content for delivery.

Data transformation takes place via synchronisation between customer data platforms (CDPs), identity managers (IDMs), and data management platforms (DMPs). These tools work together to unify data into single views of customers/leads, segment anonymous prospects into audiences, analyse data through dashboards and advanced tools, and inform next-best actions for customers. You can learn more about the important differences between these tech stacks.

At the same time, a digital asset manager (DAM) and content management system (CMS) can work in tandem to store and manage your content, ensuring it’s readily available for creating the personal experience your customers crave. DAMs manage dynamic assets designed for flexibility and reuse in a single content repository with a robust taxonomy structure, and CMSs enable personalisation capabilities that allow you to serve the right personalised content to users. To know which content is right for a user, it is important to have a taxonomy to tag assets and content in both a DAM and CMS. This ensures that dynamic content is highly available across all channels.

The output of an effective personalisation engine is a prioritised set of customer profiles with defined attributes and recommended marketing and content strategies to target them.

With customer insights and intelligent content in hand, an omni-channel output layer completes the personalised experience by delivering campaigns through customers’ preferred marketing channels.

Armed with powerful customer data insights and dynamic content, your business can utilise omni-channel activation to reach your customers with meaningful campaigns. By pairing business priorities with the personalisation architecture, you can deliver personalised content based on next-best actions across all existing channels—email, web, mobile, social, search, and more.

Omni-channel marketing platforms automate content delivery to ensure that not only are your customers receiving communication via their preferred method - they are receiving it exactly when it will be most effective. All delivered campaign outcomes are captured, and this data can be used to inform future interactions as part of your personalisation ecosystem.

This results in a personalisation stack that becomes more effective at knowing your customer base and your business as time goes on.

While a personalisation stack handles the heavy data lifting, marketing and strategy teams can utilise campaign data to reprioritise marketing objectives and plan new campaigns that align with targeted customer segments.

With a robust personalisation technology stack in place, marketing teams are freed from the manual guesswork of traditional marketing data analysis and can spend their time using rich data from campaign outcomes to develop strategy for future campaigns. This creative exercise, managed outside of the technology stack by the human decision-makers in your business, can feed back into your personalisation strategy and inform changes throughout the personalisation lifecycle, continually optimising ad spend over time.

Using personalisation to create customer value

Bringing it all together, an effective personalisation technology stack can provide business owners with excellent solutions to the impossible challenge of creating personalised experiences while trying to serve thousands of customers. Where scaling your business once meant losing the ability to create personalised customer engagement, growth now provides the opportunity to invest in and design a customer personalisation strategy that makes customers feel even more known and cared for than they had been previously. Equipped with the right tools for gathering data inputs, transforming inputs into actionable data, and delivering the right content at the right time, any business at any size can make customer interactions more effective, and most importantly, extremely personalised.
