GTM Quest editorial guide · Updated 10 October 2026

Evaluate Single Grain’s revenue marketing services by scope, attribution and client dependencies.

Practical guide · 01

Identify which part of revenue marketing you are buying

Single Grain’s own site presents revenue marketing including search, paid media and AI-related services. The proposal should identify a concrete commercial problem and the work included. A broad service portfolio does not mean every capability belongs in your initial engagement.

Your decision

Search

Define the audience questions and relevant search intent. Specify research, editorial, technical and internal-link responsibilities.

Media

Agree offer, audience and response handling. Separate media spend, creative production and management costs.

Workflow

Describe the intended AI or automation task and its review requirements. Ask how accuracy, exceptions and human approval are handled.

Practical guide · 02

Inspect revenue claims through their definitions

Revenue-oriented reporting should remain traceable to commercial records. Ask how the proposed team associates outcomes with work, treats existing opportunities and reports uncertainty. Evaluate relevant examples as case evidence rather than assuming their results will repeat.

  1. 1

    Definitions

    Agree qualified opportunity and revenue units with the sales owner. Include the time period and excluded records.

  2. 2

    Records

    Reconcile a representative result to CRM context. Distinguish a new opportunity from progression of existing demand.

  3. 3

    Decisions

    Use the report to investigate constraints and adjust the programme. Avoid treating attribution output as a complete causal explanation.

Practical guide · 03

Worked example: search traffic grows without relevant enquiries

Fictional example: a supplier sees more traffic but sales reports little useful context. The agency brief should investigate audience intent, evidence and the response path before adding more content or media.

  1. Stage 101

    Inspect

    Compare landing-page topics with target buyer questions. Review actual enquiries and reasons sales rejects them.
  2. Stage 202

    Improve

    Strengthen relevant explanations and next steps. Fix routing and commercial context where suitable buyers are being lost.
  3. Stage 303

    Review

    Assess audience fit and accepted commercial progress alongside traffic. Record what changed and which questions remain.

04/ how we work

Considering a GTM partner? This is how we work

GTM Quest is a go-to-market consultancy in London.

We define who you sell to and why they should choose you, then build the system that turns it into pipeline: LinkedIn, founder-led content, buying signals and outbound, running on a data layer you own.

We run it with you, or build it and hand it over.

The data, the tooling and the playbooks stay yours.

Every engagement is scoped and quoted in writing after the discovery call.

How much of the work do you want to own?

Handover + support

We hand over, then stay close

Everything in Handover, then a consultant stays on one or two days a week to optimise and troubleshoot.

  • ✓ Everything in Handover
  • ✓ One or two days a week of consultant time
  • ✓ Weekly optimisation calls
  • ✓ Slack and email support

Best for teams building their own capability.
