Introduction

Forget keyword stuffing and praying to the algorithm gods—traditional SEO is yesterday’s hustle. Enter AI SEO (also known as Answer Engine Optimization or Generative Engine Optimization): the art and science of engineering content that large language models (LLMs)—like ChatGPT, Google's SGE, and Bing Chat—can't resist citing.

Winning the AI SEO game demands tactics that blend structured data mastery, semantic clarity, and finely-tuned trust signals that scream credibility. In other words, your content needs to be irresistible bait for LLM citations.

Below, we’ve done the recon and identified the top 10 AI SEO agencies dominating North America and Europe in 2025. Pure-play AI SEO specialists get extra props, leaving old-school digital marketers who dabble on the sidelines. Each agency profiled brings its own flavor of cunning strategy, unique tactics, and measurable results—exactly what your company needs to crush visibility in the age of AI-native search.
