AI Overviews now appear in over 60% of Google queries in the US, and ChatGPT accounts for 20% of search-related traffic worldwide. If your SEO agency isn't optimizing for both traditional rankings and AI-generated answers, you're paying for half a strategy. These are the AI SEO agencies actually doing both.

RZLT: AI-Native Growth for B2B and Web3

RZLT combines organic search with answer engine optimization, developer marketing, and community-led growth. For startups that want an embedded growth partner rather than a vendor that sends monthly reports, RZLT fits the model.

Onely: Technical AI Search Optimization

Onely focuses on the technical side of AI search optimization: making sure AI systems can actually crawl, parse, and cite your content. Their evaluation framework covers cross-platform monitoring infrastructure, technical execution for AI discoverability, and methodology built for citations rather than rankings. For companies with complex, large-scale websites that need the technical plumbing fixed before content strategy can take effect, Onely's engineering-heavy approach fills a gap that content-first AI SEO agencies don't cover.

How to Choose the Right AI SEO Agency

Ask one question before anything else: can they show you where your brand currently appears in AI-generated answers and explain specifically how they'll change that? The AI SEO agencies worth hiring can answer with data, not promises.
