Lowering CPC in Google Ads Campaigns in Spain: Strategies and Results

Samuel Freitas · 2026-10-07

A/b ad testing

I ran an A/B test in a Google Ads campaign, where two ads with different headlines and images were shown simultaneously. The result was surprising: I was able to lower CPC by up to 30%. The ad that generated the higher click-through rate (CTR) not only improved the campaign’s overall performance, but also delivered a better return on investment. The key was testing creatives with different approaches and measuring performance in real time.

Location targeting

I used geographic targeting to focus on specific neighborhoods with high conversion rates and less competition. By limiting ads to areas where the target audience was more concentrated, I was able to significantly reduce costs. For example, after pausing ads in regions with high CPC and focusing on lower-cost neighborhoods, I saw ad spend drop by up to 25%. This strategy helped optimize the budget and drive qualified traffic.

Keyword optimization

We analyzed 50 relevant keywords for our niche, prioritizing those with high search volume and low competition. Through optimization, we removed keywords that weren’t generating clicks and focused on more specific variations that attracted a more qualified audience. As a result, average CPC dropped by 20%. This ongoing keyword analysis is crucial to keeping the campaign effective and maximizing returns.

Using ad extensions

Adding ad extensions was one of the most effective strategies. By adding sitelink and call extensions, we were able to increase CTR by 15%. This not only made the ads more visible, but also improved the user experience, leading to a higher conversion rate. Extensions are a powerful tool for making ads more engaging and informative.

Final results

When I compared monthly expenses before and after implementing these strategies, I saw a significant drop in total campaign costs. Before, the average monthly cost was 5,000 euros, and after the optimizations, it dropped to 3,500 euros. On top of that, the conversion rate increased by approximately 10%, showing that we didn’t just cut costs—we also made the campaigns more efficient.
