Editorial lanes

Three categories. One evidence standard.

One reader intent, one original angle, complete public value, visible tradeoffs, sourced claims, and a contextual next step.

01

Affiliate Operating Systems

Offer fit, useful assets, disclosure, measurement, and the operating sequence behind legitimate affiliate work.

02

SEO and Content Acquisition

Search intent, durable content, technical foundations, internal linking, and evidence-led traffic improvement.

03

AI and Workflow Automation

Responsible AI systems for repeatable work, with human review retained where accuracy, trust, and risk matter.

Duff signs his name to the work.

First-person claims, timelines, screenshots, and results appear only when the supporting evidence is available. Research and interpretation are labeled plainly.

Open notes

Start with the standards already in use.

These notes explain how AskDuff handles evidence, incentives, and editorial independence before more observations are added.

Note formats

Short when short is enough. Detailed when the evidence requires it.

Field Notes is the public operating journal, not a volume-driven content feed.

01

Observation

A concise pattern, failure, or decision worth recording while the evidence is still fresh.

02

Breakdown

A structured explanation of a workflow, tool decision, or public framework with evidence limits.

03

Update

A material change to an earlier conclusion, label, tool, policy, or build status.
