Target your advertising effectively and understand your customers better – with the Advertiser’s custom audiences service
The world of digital advertising is undergoing a major transformation – and it affects all advertisers. For example, third-party cookies are soon to be a thing of the past, and user consent for ad targeting is becoming increasingly rare. To ensure digital advertising remains effective and business continues to grow, it’s essential to adapt to these changes. But how?
With Alma’s Advertiser’s custom audiences service, you can leverage your own customer data to target advertising in Alma’s media – without third-party cookies. The service matches and compares your customer data with Alma’s extensive information on Finns, all within the Data Cleanroom interface.
This service allows you to put your customer data to work efficiently and securely. With Alma’s insights, you can, for example, target advertising effectively to your existing customers or find new customers from similar audiences within Alma’s digital network.
Additionally, the service helps you better understand your customers and their media consumption – enabling you to craft advertising messages that truly resonate with your audience and to decide which media channels are worth investing in.

Targeting existing customers or expanding your audience
Reach:
You can target ads to your own customers in various ways. Identify the most promising segments and tailor messages to suit them:
- Upsell to customers who just made a purchase
- Reactivate passive customers
- Retain and engage customers at risk of churning
- Strengthen relationships with your best customers
- You can also focus on acquiring new customers by excluding current ones from your campaign
Expand:
Expanding your custom audiences offers many benefits. New audiences help grow your business, and those similar to your current best customers are often the most promising prospects.
Use your top-performing segments to find lookalike audiences – all that’s missing are messages tailored just for them!
By targeting your advertising to precisely the right audiences, you make your campaigns more effective. You can reach the most promising customer groups and grow your business with new audiences. In addition to your own channels, you can reach your customers through Alma’s extensive network.
