You Don’t Have to Be a Marketing Expert to Drive Sustainable Growth with Google Ads
In today’s world, sustainability is no longer just a buzzword—it’s a driving force behind consumer behavior. In 2025, AI is set to transition from experimental pilots to becoming a core component of marketing operations, reshaping how brands connect with consumers. A recent study by Kantar revealed that 81% of shoppers want to buy sustainable goods, yet many struggle to prioritize eco-conscious choices due to cost-of-living pressures. This shift in consumer priorities has created a unique opportunity for brands to align their marketing strategies with environmental values. Enter digital marketing, a powerful tool that can amplify sustainability initiatives and connect brands with eco-conscious consumers.
Google Ads, in particular, has emerged as a game-changer for companies looking to promote green initiatives. By leveraging AI-driven tools and data analytics, brands can craft targeted campaigns that resonate with their audience’s values. Iberdrola, a global leader in renewable energy, is a prime example of how sustainability and digital marketing can intersect to drive meaningful results. Their Green Energy Campaign, powered by Google Ads, not only increased brand awareness but also drove significant growth in sustainable energy plan contracts. Let’s dive into how they achieved this success and what other brands can learn from their approach.
I. Iberdrola’s Green Energy Campaign: Objectives and Challenges
A. Campaign Goals
Iberdrola’s primary objective was to increase awareness of its Green Stable Plan, a sustainable energy offering that guarantees 100% renewable energy consumption. The campaign aimed to educate consumers about the benefits of switching to green energy while driving conversions and sales. In a competitive market where energy providers often struggle to differentiate themselves, Iberdrola sought to position itself as a leader in sustainability. To achieve these goals, Iberdrola turned to Google Ads as a key component of its marketing strategy.
To achieve these goals, Iberdrola needed a marketing strategy that could reach a broad audience, engage them with compelling content, and ultimately convert them into loyal customers. This required a full-funnel approach, from building awareness to driving action.
B. Key Challenges
One of the biggest challenges Iberdrola faced was differentiating itself in a crowded market. With numerous energy providers vying for consumer attention, standing out required a unique value proposition and a creative approach to messaging. Additionally, capturing consumer attention in a rapidly evolving digital landscape was no easy feat. The team needed to ensure their campaign was not only visible but also relevant and engaging.
Another challenge was balancing the need for broad reach with the need for targeted messaging. Iberdrola wanted to appeal to a wide audience while still tailoring its content to specific segments, such as eco-conscious millennials or cost-sensitive families. This required a sophisticated use of data and AI to deliver personalized experiences at scale.
II. Leveraging AI and Google Ads for a Full-Funnel Strategy
A. Top of the Funnel: Maximizing Reach and Awareness
To maximize reach, Iberdrola complemented its traditional TV planning with a digital audiovisual strategy. By integrating Google Ads’ Display Network and YouTube ads, the campaign was able to reach a broader audience across multiple platforms. AI-driven segmentation tools, such as DV360 Profile Analysis, allowed Iberdrola to personalize its messaging based on user behavior and preferences. This ensured that the right message reached the right audience at the right time.
For example, eco-conscious consumers were targeted with ads highlighting the environmental benefits of the Green Stable Plan, while cost-sensitive audiences were shown content emphasizing cost savings. This level of personalization helped Iberdrola capture attention and build awareness more effectively.
B. Middle of the Funnel: Engaging and Educating Consumers
Once awareness was established, the focus shifted to engagement and education. Iberdrola used tailored content to highlight the benefits of sustainable energy, such as reduced carbon footprints and long-term cost savings. Google Marketing Platform tools enabled the team to activate data in real time, ensuring that their messaging remained relevant and impactful.
Interactive formats, such as video ads and dynamic search ads, were particularly effective in engaging consumers. These formats allowed Iberdrola to tell a compelling story about its commitment to sustainability while addressing common consumer concerns, such as affordability and reliability.
C. Bottom of the Funnel: Driving Conversions
At the bottom of the funnel, Iberdrola leveraged AI to drive conversions. Automated clustering of users based on their propensity to purchase allowed the team to prioritize high-value leads. Value-based bidding strategies, powered by Google Cloud and BigQuery, which are integrated with Google Ads, ensured that ad spend was optimized for maximum ROI.
For instance, users who had shown a strong interest in sustainability were targeted with retargeting ads that included special offers or incentives to sign up for the Green Stable Plan. This approach not only increased conversions but also improved the overall efficiency of the campaign.
III. Results and Impact of the Campaign
A. Quantitative Success Metrics
The campaign delivered impressive results, with a 300% increase in brand searches for Iberdrola’s Green Stable Plan. Additionally, the number of contracts for sustainable energy plans grew by 22%, exceeding the team’s expectations. These metrics demonstrate the power of combining sustainability messaging with AI-driven digital marketing strategies.
B. Qualitative Benefits
Beyond the numbers, the campaign strengthened Iberdrola’s brand positioning as a leader in sustainability. By aligning its marketing efforts with consumer values, Iberdrola was able to build trust and loyalty among its audience. This not only drove short-term sales but also laid the foundation for long-term growth.
The use of Topkee’s services, including comprehensive website assessment and analysis, ensured that the campaign’s messaging was consistent and impactful across all touchpoints. Marketing strategies provided by Topkee, powered by TTO attribution tools, further enhanced conversion rates by delivering personalized ads to high-value leads.

A full-funnel approach was key to Iberdrola’s success. By balancing awareness, engagement, and conversion efforts, the team was able to guide consumers through the customer journey seamlessly. Tailoring messaging to different stages of the journey ensured that each interaction was relevant and impactful.
C. The Importance of Sustainability in Branding
Finally, Iberdrola’s campaign highlights the importance of aligning marketing efforts with consumer values.
