Technical
Your actual marketing competence, assessed in three parts: whether you start from a business goal, whether you can execute the channels you sell, and whether you can measure what you did without fooling yourself.
A channel recommendation should trace back to the client's economics. A good strategy document opens with the target. Pipeline, revenue, CAC ceiling, payback period. And works down to channel and budget allocation, with a reason each channel fits that business, that margin, and that sales cycle. An agency that jumps straight to "we'll run Google and Meta" without connecting it to the client's numbers is executing tactics, not running strategy.
Paid media: account structure, budget setting and reallocation, creative and audience testing, and the difference between platform-reported ROAS and blended MER. SEO: technical audit ability, content production system, and how links are actually acquired (we can tell manual outreach from a PBN), plus a current view on AI Overviews and LLM-driven answers intercepting clicks. Content, social, email/lifecycle, CRO, creative: depth in what you claim, shown through real work rather than a capabilities slide.
Tracking configured correctly (GA4 and GTM, conversions firing cleanly, ideally server-side tagging), and numbers that reconcile to a source of truth like the client's CRM or Shopify, not just the ad platform. A 4-level answer: a test readout that states the hypothesis, the control, the spend or sample threshold set before starting, and why you called it when you did.
Strategy ties channel choices to the client's revenue math. You show a real test readout with a pre-set decision rule. Measurement reconciles to the client's CRM. You have a current view on AI search.
Channels executed competently with results attached, measurement set up correctly, strategy present if lighter.
Tactics run but not connected to business goals. Platform metrics reported with no revenue view. Testing is ad hoc.
Can't show working knowledge of the channels you sell.
