RankScience is the SEO and AI search optimization agency built for B2B, SaaS, e-commerce and local service businesses that need measurable ROI from organic growth.

What Makes Us Different

While most SEO agencies chase vanity metrics like traffic and rankings, we focus obsessively on lead generation and revenue. We're not here to make your charts look pretty. We help you hit your growth targets and prove the value of every dollar spent on SEO.

AI Search Optimization

Beyond traditional SEO, RankScience optimizes for AI search platforms through Generative Engine Optimization (GEO), Large Language Model Optimization (LLMO) and Answer Engine Optimization (AEO). RankScience grows visibility across ChatGPT, Google AI Overviews, Gemini, Perplexity, Google AI Mode and Claude, backed by real performance data for B2B companies.

Who We Serve
  • B2B, SaaS, e-commerce and other companies of all sizes
  • Particularly effective for growth-stage companies
  • Hundreds of clients, including Zapier, Calm and Rippling
  • Strong expertise serving venture-backed startups
  • Telehealth and health tech companies seeking technical SEO excellence
  • Local service businesses in healthcare, legal, home services and professional services seeking growth through local search
Our Approach

RankScience combines technical SEO excellence with content strategy designed for both human readers and AI platforms. This dual approach means you're visible in Google today and in AI platforms tomorrow.

Founded in 2017 and based in San Francisco, we understand B2B constraints: demonstrating ROI, working with limited resources and the need to show measurable improvements quarterly. We don't do 6-month "strategy phases." RankScience delivers improvements from month one.

Services
  • SEO audits identifying ranking issues
  • AI search optimization (ChatGPT, Google AI Overviews, Gemini, Perplexity, etc.)
  • Content strategy for B2B, SaaS, e-commerce and more
  • Authority building for traditional and AI search
  • Local optimization for Google and AI platforms
  • Analytics across search engines and AI platforms

RankScience discontinued its A/B testing software, ContentEdge AI copywriting tool and PPC services in 2024 to focus exclusively on SEO and AI search optimization.

If your company needs organic growth with proven ROI, we should talk.

Rank Science really helped my business' SEO. I've worked with a lot of vendors and they're the only ones that have made a real impact. And their customer service is phenomenal! I highly recommend them.
