Direct answer
A B2B website should show approved case studies where available, plus method proof such as service architecture, process detail, QA checklists, risk registers, and launch evidence.
The useful version of this topic is practical: it should help a buyer make a better website decision, not just define a term.
Practical framework
Use the framework below to turn the topic into a page, brief, audit, or approval checklist.
- Use client proof only where approved
- Separate examples from live outcomes
- Show process and delivery standards
- Publish service architecture and decision frameworks
- Add QA and risk-reduction artefacts
- Avoid unsupported metrics or testimonials
Method proof to prepare
When public client proof is not available, method proof can still make the decision inspectable without inventing outcomes, reviews, awards, or rankings.
- Proof source inventory
- Case-study approval state
- Method proof modules
- Risk register
- QA checklist
