Single Grain is a remote-first digital marketing agency operating at singlegrain.com. Eric Siu purchased the then-failing SEO agency for $2 in 2014 and now leads its work across GEO, SEO, content, paid media, digital PR, conversion optimization, SaaS, and e-commerce marketing.
Quick facts
- Best for: Companies seeking integrated GEO, content, digital PR, and conversion support, B2B, SaaS, and e-commerce brands wanting AI-search work within a broader growth programme
- Known for: A broad GEO service, extensive AI-search educational content, and case-study roundups discussing citations, traffic, SQLs, and revenue measures.
- Contact: Eric Siu
Why it ranks
Single Grain earns the number-six position because its official GEO service covers six implementation areas that buyers commonly need together: AI-search content, technical GEO and schema, digital PR, authority building, local and brand presence, and conversion measurement. Its public case-study material discusses citations, AI referral traffic, sales-qualified leads, and revenue rather than visibility alone. It ranks below iPullRank because the reviewed evidence is more often summarized in agency-authored roundups instead of fully inspectable named client studies, but above content-only providers because its service spans technical, authority, measurement, and conversion work.
