As B2B buyers increasingly turn to search engines and AI tools for their research and decision-making, partnering with a B2B SEO & GEO agency is a strategic decision that’s well worth the investment.
Ranking on Google doesn’t guarantee a full pipeline. If your traffic isn’t converting into qualified leads, something in your SEO strategy is broken. On top of that, buyers are increasingly asking ChatGPT and AI Overviews for recommendations before a rep ever hears from them, which means a strategy built only for Google is already behind.
GEO, or generative engine optimization, is the practice of optimizing content so it gets surfaced and cited by AI platforms like ChatGPT and Google’s AI Overviews, the natural evolution of SEO as more buyer research happens inside AI-generated answers instead of traditional search results pages.
But different agencies specialize in different services. Some lean into content-led growth, others into technical SEO, and a growing number into full-service GEO.
To simplify your search for the right B2B SEO and GEO partner, we’ve done the legwork to compile a list of the top names in the field. From crafting BOFU content strategies to implementing GEO and digital PR, these agencies have the knowledge and resources to improve your pipeline metrics in competitive industries.

How To Choose a B2B SEO & GEO Agency
With search rankings more competitive than ever — and 58.5% of all U.S. Google searches now resulting in zero clicks — a top-tier B2B SEO and GEO agency can help your brand climb rankings, capture organic pipeline, and hold its ground in a crowded market.
Meanwhile, the rise of AI-powered search means B2B brands need to think beyond traditional rankings entirely. Buyers increasingly form their first impression of a brand from an AI Overview or a ChatGPT answer, not a blue link. This means the agency you choose needs to optimize for both surfaces from the start, rather than treating GEO as a bolt-on.
When evaluating potential partners, consider these qualities shared by the best agencies:
- Proven industry expertise: Does the agency have a long track record in B2B SEO and GEO, as well as direct experience with clients in your sector?
- GEO and AI readiness: Can the agency optimize content for both traditional search engines and AI platforms such as ChatGPT and Perplexity using a dedicated methodology, or is GEO handled as an add-on by a separate team?
- In-house production: Are designers and editors part of the core team, or is that work outsourced? In-house talent tends to move faster and maintain consistent quality across a large content library.
- Proprietary insight: Does the agency rely solely on third-party tools like Ahrefs, or have they built their own way of identifying opportunities competitors can’t see?
- Pipeline alignment: Does the agency map content to your sales funnel, or does reporting stop at traffic and rankings? The best partners can show how content moves prospects from awareness toward a sales conversation.
- Client success stories: Look for case studies that demonstrate measurable results — pipeline growth, traffic value increases, and conversion improvements — not just rankings.
