A no-hype review of AI tools for paid advertising — what genuinely improved performance and what was mostly noise.

The AI marketing tools market has exploded. Every week there's a new product promising to automate your Google Ads, write better ad copy, or predict your audience's next move. We've spent three months testing six of the most-discussed tools across real client accounts. Here's what we found.

What we tested

We evaluated tools across three categories: bidding and budget optimisation, creative generation, and audience intelligence. The tools ranged from well-established platforms to newer AI-native startups.

What actually helped

The tools that delivered measurable results fell into two categories. First, AI-assisted creative testing: tools that helped us generate and systematically test more ad copy variations than we could manually produce. One client saw a 23% improvement in CTR over 8 weeks purely from higher creative throughput. Second, anomaly detection: tools that flag unusual changes in performance metrics in real time, allowing faster responses to budget spikes, quality score drops, or competitor activity.

What disappointed

Automated bidding "optimisers" that sit on top of Google's own Smart Bidding often conflicted with the algorithm, producing worse results than simply setting a Target CPA and letting Google's system work. Similarly, audience "prediction" tools added complexity without clear uplift.

Our honest take: AI is genuinely useful in PPC when it augments human judgement and speeds up manual work. It's not yet able to replace strategic thinking.
