This definition of personalization may sound similar to another concept: customization. But there is a clear difference. With personalization, a company modifies an experience without any effort from the customer. Customization, on the other hand, allows the customer to modify the experience themselves intentionally.
For example, when you adjust your Gmail settings to indicate the number of messages you want to see per page and add a signature, you are customizing your email experience. But when Gmail displays advertisements based on your interests, it personalizes your experience for you. In the first example, you’re intentionally changing the experience. In the second, you receive more relevant ads without taking any direct action yourself.
Let’s explore another example we’re all familiar with: online shopping. Many e-commerce sites allow you to filter the products shown on a page to help you more easily locate the ones that meet your specific criteria.
That’s customization. You are intentionally customizing the products you see on that page to help you find what you’re looking for more quickly.
But a site could deliver a similar result — helping you find the product that best meets your needs — without requiring you to take action yourself. Instead, the site could sort the products on the page and list those at the top that meet the preferences you’ve demonstrated by your behavior. For example, if you regularly shop and purchase home decor in black and brushed nickel, it might display those items toward the top of the list. This way, you can find those products more quickly without needing to scroll through pages of irrelevant gold or white decor first.
In another example of customization vs. personalization, let’s consider email frequency. When you sign up to join a company’s email list (or when you attempt to unsubscribe), companies offer you the option to modify your preferences to dictate how often you’d like to receive emails (daily, weekly, etc.).
This is another example of customization; you tell the company how often you’d like to hear from them.
But you could reach the same end result (more or fewer emails) with personalization, too. In that case, the company would pay attention to how often you tend to engage with their email communications and adjust the frequency of email sends accordingly. Recipients who tend to open and interact with more emails will receive emails more frequently, while those who only interact occasionally will receive emails less frequently. That’s personalization.
With both personalization and customization, the end result is a more relevant experience for the customer. The difference is whether the customer does the work or not.
