WebFX Top pick
The heavyweight — huge team, mature process, deep reporting. Strongest on traditional SEO delivery; its edge is scale, not AI-search specialism.
SEO still decides what gets pulled into AI answers — but the agencies that win now also make a brand readable and citable by AI engines, not just ranked on Google. We scored agencies on delivery, expertise, AI-search readiness, outcomes and trust, with extra weight on that last frontier.

The heavyweight — huge team, mature process, deep reporting. Strongest on traditional SEO delivery; its edge is scale, not AI-search specialism.
Pure-play SEO with a systematic, transparent method, and more invested in modern AI-search tactics than most specialists its size. A focus-over-breadth choice with the depth to hold second.
The highest AI-search readiness in the list — a GEO/AEO specialist first, SEO second. On broad SEO delivery it sits behind the larger pure-play firms; pick it when the gap is being invisible to AI engines rather than raw ranking horsepower.
Content-and-links specialist with editorial quality that holds up — strong for winning on genuinely good content.
Growth agency that leans into AI-search tactics more than most large shops, paired with paid and content.
Not a classic SEO shop — a pure AEO/GEO consultancy. Worth a look only if your gap is AI-search visibility rather than traditional rankings; for broad SEO delivery, the firms above go deeper.
Full-service breadth with a real SEO core; AI-search readiness is not its headline.

Go deeper before you choose.
Yes — more than ever. AI engines run searches and synthesise the short list they get back, so ranking and being readable to those engines feed each other. Take SEO out and there's nothing for AI to cite.
It's whether AI engines can read, trust and recommend your brand. It overlaps with SEO but adds entity clarity, citable content and structured answers tuned for how LLMs pull and synthesise sources.
Match strength to need. For scale and full-service, the large agencies fit. If your problem is that you rank but stay invisible to AI engines, pick a team that treats AI-search visibility as the core discipline.
