Verdict: First Page Sage is legitimately one of the best GEO agencies in the world — they pioneered the discipline and their research output is outstanding. For UK regulated B2B businesses, MarGen is the better choice: London-based, UK regulatory expertise, and priced for UK SMEs and mid-market companies rather than US enterprise budgets.

Where First Page Sage is stronger
GEO methodology leadership. First Page Sage genuinely pioneered the GEO discipline and publishes the most comprehensive original GEO research available anywhere. Their thought leadership is exceptional.
Enterprise track record. Working with Salesforce, Logitech, and complex B2B companies gives them a depth of enterprise-scale GEO evidence that newer agencies cannot match.
AEO + GEO combined depth. First Page Sage delivers outstanding integrated AEO and GEO programmes with strong client review scores (4.9/5.0 across multiple platforms).
Where MarGen is stronger
UK regulatory context. FCA Consumer Duty, SM&CR, and operational resilience frameworks are not things a San Francisco agency understands from first-hand regulatory experience. SRA Transparency Rules, RICS valuation standards, and NHS procurement frameworks require close familiarity with UK professional body guidance that US agencies simply cannot replicate. GEO content for regulated sectors is citation-worthy in direct proportion to its regulatory accuracy.
UK pricing. At $5,000–$15,000/month, First Page Sage is priced for US enterprise budgets. MarGen from £2,500/month is calibrated for UK regulated SMEs and mid-market businesses.
UK time zone and market. Regulatory changes happen in real time — FCA consultation papers, SRA rule changes, NICE technology appraisals. A London-based team that monitors UK regulatory developments as they happen produces more current, more citation-worthy content than a US-based agency working eight hours behind.
