The Four-Gate Diligence Stack
The Four-Gate Diligence Stack: 4 public documents serious buyers inspect before they move into pricing — including six-month replacement coverage in writing.
You are about to spend money with a fulfillment partner. Before that happens, you want to read what they say in public when no salesperson is in the room. That is what this page is. Four gates, four documents, all readable in under ten minutes: what quality actually means, how publishers are screened, what the operating commitments are, and where the six-month replacement coverage begins and ends — backed by 13,277+ campaigns of operating history since 2009.
The Four-Gate Diligence Stack is the diligence layer of the Public-Diligence Fulfillment System — the umbrella that runs proof, diligence, delivery, and remedy across every engagement.

Executive view
Most diligence questions fit inside the same four gates.
Serious buyers usually want to know whether the standards are public, whether publisher approval has a real methodology behind it, whether the operating commitments are spelled out, and where guarantees or exclusions begin and end. That is the whole stack.
Gate 1 · Standards
What qualifies as acceptable quality, editorial fit, monitoring, and replacement-worthy failure.
Gate 2 · Methodology
How publishers are actually screened, rejected, and approved before they ever appear in delivery.
Gate 3 · Commitments
What response, communication, confidentiality, and delivery expectations exist after purchase.
Gate 4 · Coverage
Where guarantees, credits, restoration, and exclusions apply in plain English, including six-month replacement coverage for qualifying dofollow placements.
Use this center by question
Most buyers are clearing specific risks, not collecting policy pages.
Pick the route that matches the actual blocker. That keeps diligence tight, useful, and easier to move through when leadership wants fast answers.
Quality rules
What standards define a qualifying placement?
Start here if you want the public definition of site quality, editorial fit, monitoring, and replacement triggers.
Approval logic
How do you decide which publishers are safe enough to use?
Open the methodology when you want traffic validation, topical-fit logic, and spam-footprint exclusion.
Operating commitments
What happens after we buy?
Move into the SLA for response windows, confidentiality, communication expectations, and service commitments.
Coverage limits
Where do protections apply and where do they stop?
Read the plain-English coverage page for guarantees, credits, exclusions, and cancellation timing.
What buyers usually want summarized
The commitments most people want before they read the longer pages.
This table is the fast answer layer. Use the linked documents when you need the full definition, process, or policy wording behind each summary.
| Question | Short answer | Best page |
|---|---|---|
| How do you filter bad sites? | By qualifying organic visibility, topical fit, and rejecting spam, PBN, link-farm, or penalty-risk footprints. | Methodology |
| What counts as a covered quality issue? | Covered removals, degraded links, and qualifying publisher-quality failures can trigger restoration or comparable replacement. | Editorial Standards |
| What service commitments exist? | The SLA outlines acknowledgment windows, communication expectations, confidentiality, and operational guardrails. | SLA |
| What if something cannot be delivered or maintained? | Guarantees, credits, and exclusions live in the refund policy and the linked replacement language from standards. | Refund Policy |
Trust and proof belong together
Documentation reduces risk. Proof closes the fit question.
If this center clears the diligence barrier, the next useful move is usually evidence, not more policy. That means aggregate proof, case studies, or decision-stage pricing—not another lap around the compliance parking lot.
Proof hub
Proof Library
Choose proof by persona, blocker, or campaign pattern.
Aggregate proof
Results
