Google Ads optimization in 2025: AI, automation, and smart bidding strategies

The world of Google Ads has undergone an unprecedented transformation in 2025. With the introduction of AI Mode, extensive AI Overviews, and revolutionary bidding strategies, the digital advertising world is on the verge of a new era. For Dutch and Belgian companies, this means both opportunities and challenges to maximize their online visibility.

Where traditional optimization focused on manual adjustments of keywords and bids, modern Google Ads optimization revolves around the smart deployment of AI-driven tools. Performance Max campaigns dominate the landscape, while Smart Bidding Exploration opens up new possibilities for advertisers willing to leave their comfort zone.

This transformation affects all aspects of online marketing, from SEO strategies to e-commerce optimization.

The new reality of Google Ads in 2025

AI as a foundation, not as a feature

"AI is no longer something that helps with campaigns, it is what drives successful campaigns," says Vidhya Srinivasan, VP Ads at Google. This shift is fundamental to how we look at advertising optimization.

The introduction of AI Mode has completely redrawn the search experience. Users searching via AI Mode spend 2 to 3 times more time on websites they discover through ads. This offers noticeable opportunities for performance marketing strategies, especially in combination with AI-driven content creation.

“The line between creativity and technology is disappearing. The most effective campaigns today are not only emotionally resonant, they are also driven by data, algorithms, and automation.”

— Shubhranshu Singh, CMO Tata Motors

Performance Max evolution: from black box to transparency

One of the biggest frustrations of advertisers was the lack of insight into Performance Max campaigns. Google has listened and now offers channel-specific reporting within Performance Max. This finally means visibility into how ads perform on Search, Display, YouTube, and Discovery.

The new Power Pack replaces the Power Pair and consists of:

• AI Max for Search campaigns

• Performance Max (with improved reporting)

• Demand Gen campaigns

This combination offers a more holistic approach to automated advertising, where each component serves specific goals within the larger ecosystem. For companies that want to outsource digital expertise, understanding these new campaign structures is essential.

Smart Bidding Exploration: the biggest bidding update in a decade

Google has announced that Smart Bidding Exploration is the biggest update to bidding strategies in ten years. This feature explores less obvious but potentially high-value search queries, automatically adjusting bids.

“Costs are rising, but so are performance - 65% of sectors saw better conversion rates in 2025. The main conclusion is that a smart strategy is better than cheap clicks.”

— Cliff Sizemore, Senior Marketing Manager LocaliQ

Practical implementation of Smart Bidding

The new bidding strategy dynamically adjusts bids, sometimes even above your set ROAS goals, to capture more valuable traffic. This requires a fundamentally different mindset, as described in our performance marketing guide:

• Trust machine learning: Let algorithms discover patterns that people miss

• Focus on volume and value: Not just on cost per click

• Monitor performance holistically: Look at total account performance, not individual campaigns

This approach fits perfectly with modern advertising strategies within the marketing funnel.

First-party data: the new gold standard

With the phasing out of third-party cookies, first-party data is becoming more crucial than ever. Companies that smartly integrate their customer data into Google Ads see significant improvements in targeting and performance. This is especially relevant for AI automation strategies that depend on quality data.

Implementation of Enhanced Conversions

Enhanced Conversions use hashed first-party data to improve conversion tracking. According to recent benchmarks, advertisers who implement Enhanced Conversions see an average of 11% more registered conversions.

Required implementations for 2025:

• Server-side tracking for more accurate measurements

• Google Consent Mode v2 for privacy compliance

• Offline conversion tracking for complete customer journey insight

• Integration with CRM systems for improved audience targeting

For an in-depth analysis of your current setup, consider an AI audit for your company to identify opportunities for optimization.

Video-first approach: from text to moving images

The focus on video ads exploded in 2025. Google has introduced new tools that make it easier to create video content:

Veo and Imagen integration

Google's advanced AI models Veo (video) and Imagen (images) are now directly available in Google Ads. This means that advertisers:

• Can create image-to-video conversions from product photos

• Can create AI-generated video ads with simple text prompts

• Can add interactive video elements to YouTube Shorts Ads

These developments seamlessly align with trends in AI marketing and the broader application of AI in online marketing.

“Tools that empower storytellers don't just make things easier. They change the way we tell stories.”

— Brandon Baum, Content Creator

Merchant Center revolution for e-commerce

For Shopify webshops and other e-commerce platforms, Google offers significant updates. These integrate perfectly with Shopify marketing strategies and conversion optimization for webshops.

A/B testing in Merchant Center

Companies can now test different product titles, images, and descriptions directly within Merchant Center. This offers a direct way to optimize product presentations without external tools.

New possibilities:

• Product Studio: AI-driven product photo creation

• Lifestyle images: Context-rich product presentations

• Brand Profiles: Consistent brand presentation across all touchpoints

• Video assets: Moving product demonstrations directly in search results

For companies that want to set up their webshop or migrate to Shopify, these tools are indispensable.

Practical optimization strategies for 2025

1. Embrace the AI-driven workflow

Traditional SEO strategies need to be adapted for AI search experiences. Focus on creating "helpful, reliable, people-first content" that can appear in both traditional search results and AI Overviews. This aligns with the evolution of GEO (Generative Engine Optimization).

Action points:

• Optimize website content for AI Mode discovery

• Implement structured data for better AI understanding

• Focus on long-tail keywords that support conversational search

For more insight into these developments, read our articles on voice search optimization and zero-click SEO.

2. Data-driven decision-making

With gtag, websites receive 11% more signals compared to traditional tracking. Upgrading to gtag is not only recommended but essential for accurate performance measurements.

Implementation checklist:

• Migrate to gtag for improved signal collection

• Implement Enhanced Conversions for better attribution

• Integrate offline conversion data for complete customer journey insight

This approach is extensively discussed in our digital marketing analysis methodology.

3. Automation with control

The new generation of Google Ads requires a balance between automation and human oversight. The introduction of Google Ads Expert and Google Analytics Expert as AI agents offers support, but strategic decisions remain a human domain. For teams that want to follow AI training, this is a crucial component of modern marketing competencies.

Advanced targeting in the privacy era

Audience intelligence without cookies

Modern targeting requires creativity within privacy restrictions. Successful advertisers use:

• In-market audiences: Users who are actively searching for similar products

• Custom intent audiences: Based on specific behavioral patterns

• Lookalike audiences: Derived from first-party customer data

“The time of spending hours optimizing cost-per-click and ad copy is over. You can gain a lot from landing page optimization.”

— Team Kersvers Digital

Remarketing renaissance

Remarketing strategies are becoming more refined with AI support. Dynamic remarketing combines first-party data with machine learning to display personalized ads at different stages of the customer journey. This is particularly effective in combination with CRO techniques and lead generation strategies.

Measurement revolution: from backwards to forwards

Google is shifting from looking back to looking forward. The new measurement methods focus on predictive insights instead of historical performance.

Incrementality testing for everyone

The minimum spend for incrementality testing has decreased from $100,000 to $5,000, making advanced measurements accessible to small and medium-sized businesses.

Benefits of incrementality testing:

• Measure the actual impact of advertisements

• Optimize budget allocation between channels

• Identify audience overlap and cannibalization

Industry benchmarks 2025

According to WordStream's analysis of 16,446 campaigns between April 2024 and March 2025:

Average performance per sector:

Sector	Average CTR	Average CPC	Conversion rate
E-commerce	3.17%	€1.16	3.75%
Legal	4.81%	€6.75	3.84%
Real Estate	3.71%	€2.37	2.47%
Technology	2.09%	€3.80	2.72%
