Fit GEO into the broader marketing plan
Single Grain’s agency history traces Eric Siu’s $2 purchase in 2014 and describes its subsequent broader marketing practice. Compare its role across SEO, content and other acquisition work against the support your B2B, SaaS or ecommerce team already has.
Turn the service menu into a defined scope
The GEO page describes question research, knowledge assets, technical improvements, digital PR, local and brand presence, and conversion support. Request the actual deliverables and responsible teams; a broad capability list does not define your contract.

Connect reporting to the buying decision
Agree how visibility, citations, referral visits, qualified enquiries and revenue are separated. Request a relevant named case and underlying period rather than treating an agency-authored roundup as proof of its own client delivery. Keep account and content access in the written proposal.
