The age of third-party data is nearly over… Don’t go down with the ship.
The parties were fun, money was made, but owned data, i.e., zero-party data and first-party data, is the future. eCommerce brands that don’t prioritize their owned data simply won’t last the next few years.
We’ve covered the magic of zero-party data, so let’s focus on how brands win when they know how to leverage their first-party data. First-party data opens up a world of opportunity for smarter segmentation and ultimately, more personalized customer experiences.
First-party data (aka 1st-party data or 1P data) is information collected from your customer base, subscribers, and site visitors when they interact with your site or marketing, or when they make a purchase.
First-party data is valuable because, like zero-party data, it comes directly from your customers. This means it is accurate, reliable, and insightful.
Here are some of the most prominent categories of first-party data with examples of each category:
Since 1P data collection comes directly from your customers’ interactions with your brand, you gather it from four major sources, which can help you answer many questions about your customers:
Building a comprehensive first-party data strategy is vital to the future of your business.
With third-party data collection and cookies being phased out (the Cookiepocalypse!!) over 2022 and 2023, your company’s 1st-party data (and zero-party data) will be crucial for success.
Here are some ways you can leverage it to fulfill your business goals.
1P data helps brands build accurate customer profiles to better predict purchasing patterns.
For example, you might have a high-converting customer profile for a certain product category, with specific buying interests and behavior. In this case, you can predict that new visitors matching this profile will share similar buying preferences: this tailors your messaging to the profile, and will increase conversions.
Additionally, you can more directly predict future purchases based on historical individual buying behavior. By leveraging the metric time between orders, you can send replenishment emails to individual customers who might be ready to purchase again.
Sounds personalized, doesn’t it? Speaking of personalization…
Customer experience is a key brand differentiator, and true marketing personalization is key to delivering the best experiences, so that every customer feels special.
But how do you “personalize” experiences? How do you determine your customers’ interests and tailor your value prop accordingly? By leveraging 1P data. (Okay, you saw this coming.)
With 1st-party data, you can personalize your campaigns across every channel. You can personalize your upselling and cross-selling recommendations and send tailored holiday buying guides to your customers’ inboxes and phones.
In the interest of delivering better, more personalized experiences, creating customer segments is crucial.
1st-party data helps you build more accurate customer profiles, and it also fuels better segmentation. With 1P data-driven segmentation, you can better account for factors like your audiences’ time zones, interests, and purchasing power.
And the importance of smart segmentation extends beyond personalization—it also helps you determine your most valuable customers.
As a business owner, knowing your most profitable customers is integral. Which of your customers have the highest customer lifetime value? And which customers are spreading the word about your brand?
Identifying most valuable customers helps eCommerce brands drive repeat purchases through smarter upselling and cross-selling, and equally importantly, it helps you identify which customers you should prioritize retaining.
Faster, more accurate order deliveries are key to winning over today’s consumers. But optimizing your shipping network to offer an Amazon-like level of fast shipping requires a lot of time and money. Instead of catching up to Amazon by spending billions on warehousing space, you can leverage first-party data to optimize your fulfillment center locations.

Although 92% of marketers believe understanding first-party data is critical to growth, we see many brands struggling with first-party data, both in collecting it and leveraging it.
Modern eCommerce brands are dizzy with data. You may be selling on Shopify, Amazon, Magento (or some combination of the three), so you have multiple sources of first-party data to begin with.
Then, when you layer in Klaviyo, Attentive, ReCharge, Google Analytics, and other tools, you have a ton of siloed first-party data that you need to roll up your sleeves and block out a few days (or weeks) to make sense of.
To optimize your customer profiling and segmentation, you need a deep understanding of their interests, behavior, and preferences. Unfortunately, because many brands struggle to create a single source of truth, they fail to leverage their data for growth.
To build a single source of truth, we recommend leveraging an analytics platform that centralizes all your data. Once you do, you can make smarter decisions that drive growth for your brand.
How do you know if your marketing campaigns are successful? And more importantly, how do you quantify their success? Should you increase your ad spend or cut it down? Should you experiment with different email creatives and copy, or stick with your existing material?
Your first-party data and a great testing strategy will allow you to track the metrics to answer these questions.
For example, If you’re spending around $1000/month to capture 100 email addresses on Google, and 20 of those subscribers convert, is your ad spend justified?
If you track your customer lifetime value by channel, and your CLV for customers acquired through Google is $150, then your ad spend is more than justified. You’re printing money! You would want to increase your ad spend.

If you weren’t collecting and analyzing your 1st-party data, you wouldn’t have been able to come to this sort of insight on your ad spend.
First-party data truly shines when it’s leveraged via RFM analysis, a highly effective way to measure your customers’ value and engagement over a time period (usually, 45, 90, or 180 days).
RFM is based on three dimensions of customer behavior:

An RFM-backed marketing strategy helps tailor your efforts to retain high-value customers (HVCs, who have RFM scores of 1 or 2) and gives you the confidence to part ways with unenthusiastic customers (who have poor RFM scores).
Our two major recommendations for any eCommerce brand around RFM are:
