Personalisation

Also known as: personalised experiences

Personalisation is the practice of adapting content, offers, recommendations or messaging to a specific person or segment based on data you hold about them. It ranges from simple rules, such as showing a country specific price, to model driven recommendations. The aim is to make the experience more relevant to the individual than a single default version would be.

What it is

Personalisation changes what a user sees based on signals such as location, device, referral source, past behaviour, account status or declared preferences. It can be applied on websites, in apps, in email and in ad creative. Segment level personalisation groups similar users together, while one to one personalisation targets individual behaviour.

Why it matters

Relevance usually improves conversion, retention and revenue per visitor, because fewer users have to work to find what applies to them. It also matters for discovery, since assistants and AI answer engines increasingly resolve a user's context themselves, which raises expectations of what a brand experience should do. Poorly executed personalisation, though, can hide important content, confuse crawlers or feel intrusive.

How it works

Teams define segments and the decision logic, connect a data source such as a CDP or CRM, then deliver variants through a personalisation engine, CMS rules or an email platform. Changes are validated with A/B or holdout testing so the lift is measured rather than assumed. For search visibility, practitioners keep a stable, crawlable default version of each page and personalise secondary elements rather than core indexable content.

When it applies

It applies when you have enough reliable data about visitors or customers, and enough traffic, to make variant experiences worth building and measuring. It is most valuable on high intent pages, in logged in product experiences and in lifecycle email.

Examples

  • An ecommerce homepage promotes a different category banner to returning visitors based on the last category they browsed.
  • A B2B site shows industry specific case studies to visitors from named target accounts identified by firmographic data.
  • An email platform sends a restock reminder only to subscribers who previously viewed the out of stock item.

How it is measured

  • Conversion rate of personalised variant versus control or holdout group
  • Revenue or pipeline per session by segment
  • Engagement with personalised modules, such as click through rate on recommended items
  • Coverage rate, meaning the share of sessions that are eligible for a personalised experience
