How to identify users and track their behavior even after cookies are regulated
From the perspective of privacy protection, tracking user behavior on the Internet is becoming regulated.
How to track users for analytics in a privacy-first, cookie-less future
In the first place, a cookie is an identifier for a person who visits a website. Cookies allow websites to store user browsing information and input information on the user's PC and retrieve that information from the second and subsequent accesses. It allows you to identify individual users who visit your website, so you can track the behavior of a particular user, but if the cookie is denied, it becomes impossible to track. If cookies are not available, the second and subsequent visits to the website will be recognized as a different person from the first visit.
For websites, knowing 'what the user was doing before the conversion' is directly linked to sales. However, when cookies are not available, it is difficult to know what transitions and behaviors individual users are taking on the page. There are various analysis tools such as Google Analytics, but it is difficult to cross multiple analysis tools.
Meanwhile, Narrator , a data analysis platform provider, explains in a blog 'How to identify users even if cookies are abolished.' The figure below clearly shows the method. The flow is shown in which a person who clicks on a Facebook advertisement and visits an online shopping site purchases a product. At this time, a parameter unique to the URL of the Facebook advertisement is attached, and when the user purchases the product, the user is given an identifier called an email address, and the corresponding email address and the parameter are linked to all the user's actions on the website. It is a mechanism to grasp.
Specifically, the following three steps enable user identification.
Step 1: Track all page views and sync them with your 'data warehouse'
Step 2: Identify the user with a unique URL
When a user first visits a website, they are anonymous. In this anonymous state, you have two options to know 'who is on your website':
1. 1. Use a unique, non- PII (personally identifiable information) URL
2. Use the identification function of an existing page view tracker
If you are using '2', Narrator recommends '1' because you may get stuck in Chrome extensions. Methods include adding a unique 'order_id' or 'subscription_id' to the thank-you page that appears after purchase or subscription, or adding a unique 'contact_id' to the URL in the email. I have.
Step 3: Connect users with anonymous pageviews
Through the work of Step 1 and Step 2, 'Page views assigned unique and consistent anonymous identifiers for each user' and 'Identifiable user behavior data such as orders, subscriptions, emails, etc.' You can get it.
Using these, first search the data warehouse for page views that include 'order_id' in the URL and get the customer's email address. Find the anonymous ID from the pageview with order_id and overwrite the one used as the identifier from the 'email address' to that 'anonymous ID'. This will allow you to assign a user-identifiable ID to all page views.
