Updated databases: the engine of growth for advertising agencies

In an increasingly competitive B2B environment, the quality and updating of databases has become a key factor for marketing and advertising agencies to maximize the effectiveness of their campaigns.

In the marketing and advertising ecosystem, having up-to-date data is essential. For agencies, a well-managed database can be the difference between effective campaigns and wasted effort. However, simply having a large number of contacts isn’t enough: quality, verification, and updates are key factors.

Let’s explore the best practices and technological solutions that agencies can adopt to build and maintain effective B2B databases.

Why is an up-to-date B2B database so important for an agency?

1: Improved Segmentation and Personalization
Up-to-date customer data—such as role, industry, advertising investment, and company size—allows for the design of relevant messages. An outdated database with incorrect contacts can generate a multitude of problems.

2: Reduced Resource Waste
Every email, every phone prospecting campaign, or direct contact that doesn’t reach its target is a wasted resource.

3: Improved Reputation and Deliverability
Using incorrect contacts risks increasing bounce rates or being flagged as spam, which can negatively impact domain reputation, whitelisting, or sender reputation.

A concrete example: Many companies offer industry-specific databases, such as advertiser or advertising agency databases. However, if this data isn’t updated frequently, its usefulness will decline drastically after a few months.

What characteristics should a good marketing database have?

For a database to provide real value to an agency, it should have the following characteristics:

– Automatic periodic updates: ideally every 60 or 90 days. For example, Blinko claims to update its data continuously to ensure it remains up-to-date. blinkogroup.com

– Real-time verification: especially for emails, phone numbers, and accounts of each advertiser.

– Coverage of different roles/levels: CEO, marketing directors, brand managers, communications directors, etc., to address multiple touchpoints within a company.

– Data enrichment: combining company data such as revenue, number of employees, etc., with other high-value data such as advertising and social media spending.

– Segmentation: by sector, geographic location, advertising investment, etc.

-Legal compliance and consent: especially critical in the EU, with laws such as GDPR regulating data use, explicit consent, right to be forgotten, etc.
