The privacy changes initiated by Apple and the changes in user-level tracking introduced by Facebook and Google will lead to a decline in third-party cookies. Over the next few years, as these privacy-minded companies become more prevalent, many of the old marketing avenues will disappear. One of these significant and immediate changes is the decline of third-party cookies.

Many marketers have relied upon digital-based marketing attribution models throughout their careers as the be-all and end-all of marketing measurement. But with every technology change, they're left scrambling to keep up. Right now, only 11 per cent of marketers are considered "excellent" at tracking marketing performance in the unique landscape of granular data and consumers that respect privacy.

Despite the changes in the digital marketing industry, opportunities exist. Marketers who proactively create a strategy to prepare for an advertiser's inability to target with cookies and hyper-targeting will be rewarded in the future. However, before diving into plans for this future, let's first understand why marketers scramble for solutions.

What are cookies?

There are two different types of cookies. First-party cookies let the website know that you've already been to a particular page and also let you save data on your browsing, like your preferences or password. Third-party cookies are becoming obsolete, but first-party ones are just as important now and always have been.

First-party cookies are set by and sent to the website domain you're on.

First-party cookies are typically used to improve a user's browsing experience and are not shared with third-party advertisers. These are often seen in the form of autofill, which lets users quickly fill out forms or enter their login credentials. With these cookies, only the user and the website can access them - outside advertisers cannot get access.

Recently, Google reassured internet users everywhere that they have no beef with first-party cookies because these convenient data stores are here to stay for a long time.

Third Parties Cookies

Advertisers primarily use them to understand user activity better and make relevant advertising decisions. When a consumer visits a site, they get a cookie from the website, and often, the website will share them with advertisers. This way, advertisers can gain an in-depth view of their consumers' online activity. Information like where they've been recently and what they've done on that site becomes available to help marketers make better decisions about their ad campaign effectiveness.

As consumer awareness around data privacy continues to grow, third-party cookies are predicted to become obsolete. A significant factor in this prediction is the continued adoption of features like "Do Not Track" by web browsers, including Chrome, Firefox, Safari, Edge, and Brave. Marketers need to make adjustments soon to stay relevant.

Implementing Cookieless Entry & Tracking

As third-party cookies are outlawed, marketers must find ways to track users without cookies. Luckily, there are many ways to track customers that don't rely on cookies. The best methods for future-oriented marketers won't require the use of cookies...

The move from cookies to cookieless will require more than a few minor changes to your strategy. It requires you to think about the future and how to transform your system to become more compliant with the many privacy changes that are taking place. It might be time for you to consider one of these options...

First-party data is a great way to understand your customers deeply.

To collect first-party data, you must ask customers to share their information in exchange for a reward. For example, giving users free shipping for every email they provide is an easy way to incentivize your customers into signing up.

However, before you ask your consumers to share their data, ensure it is high-quality. More isn't always better - ask yourself: How will the data provide value? What risks are involved in storing the data? Do you have methods to share the data within your organization securely? If you can answer all easy questions confidently, it's worth asking for personal data.

PRO Tips – So, if you hypothesize that women over 35 like your product more than the general population, you could launch two campaigns in a similar geographic area – one for women over 35 and another untargeted campaign – and see whether or not your prediction is true. From there, you can invest your marketing funds accordingly. This method doesn’t require much in the way of personal information, making it ideal for a cookieless future.

Use Customer Data Platform

A customer data platform (DMP) will help you aggregate data to connect it to your customers' demographic traits. For example, if 25% of your recent media traffic has primarily come from millennial women in the Eastern US who own bikes, data de-aggregation would show that these individuals are the target audience for a bike company. This context is critical for marketers who will soon lose access to third-party cookies, meaning they'll have no way of knowing how many customer impressions they receive.
