Personalization means the product, not the user, does the tailoring. On this site it covers self-segmentation questions in onboarding, examples that use your own domain or data, recommendations that connect to an earlier answer, and the failure case: generic stock examples shown after the product already has access to your real content.
Sriram Kalyanaraman and S. Shyam Sundar (2006) showed students web portals with low, medium or high levels of tailoring and found that more tailoring produced more positive attitudes toward the portal, partly because the content felt more relevant. A meta-analysis by Seth Noar and colleagues (2007) of 57 health-communication studies found that tailored messages outperformed generic ones, but the average effect was small. NN/g's Amy Schade warns that personalization only helps when the system guesses correctly, and some users find accurate guesses unsettling.
In onboarding the cheapest personalization is reusing what the user just told you. Asking a role or goal question and then showing the same generic screen wastes the user's effort and teaches them that answers don't matter.
How to use it
- Use every onboarding answer visibly on the next screens, for example "Recommended for you" tied to the plan or template they chose.
- Replace stock examples with the user's own data, domain or content as soon as you have access to it.
- Let users correct a wrong guess in one tap, and say why something was recommended.
Watch out
- Using data the user didn't knowingly share, or showing that you know too much, feels invasive rather than helpful.
- Asking segmentation questions that change nothing adds friction with no payoff.
