The decision problem

A January SERP capture can accurately document January and still be unsafe for a July investment decision after a product launch, algorithm change or market-entry event. Source reputation does not prevent evidence decay.

SERPIFAI Core Framework

Evidence Freshness and Reliability Standard

Decide what a specific evidence record may support now.

Decision question
Can this record support this exact claim, context and decision?
Governing rule
A source name or timestamp is never enough. Test provenance, age, directness, reproducibility, context fit and decay risk together.
Governed output
Current, Degraded, Stale or Unresolved—with a permitted use and reopen trigger.
Boundary
This standard governs evidence fitness. It does not prove causality, forecast rankings or validate commercial outcomes.
Run the 30-second checker
Quick answer:

Use evidence only when its provenance, observation date, directness, reproducibility, context fit and review window are explicit enough for the decision. Otherwise qualify the wording, refresh the record or hold the claim.

Before an investment decision

Can a January competitor ranking report support July budget allocation?

Evidence: competitor ranking report collected in January.

Decision: whether to fund a six-month content programme in July.

ControlResultDecision implication
ProvenancePassThe source and January collection date are known.
Observation ageOutside windowThe evidence is older than the declared budget-review window.
Context fitChangedThe competitor launched new pages and the SERP set changed after collection.
Decay riskHighA material investment could be based on an opportunity that no longer exists.
Outcome Degraded — refresh before the funding decision.

The January report may remain useful as historical context, but it cannot be the sole basis for July budget allocation.

Use the tool

30-second evidence fitness checker

Compare the record’s age with its declared review window, then test whether a material event, context mismatch or contradiction makes the record unsafe. The checker runs locally in the browser and sends no data.

Fast path
Advanced evidence controls
Governed output

Current

The record is inside its review window, context-matched and has no known superseding event.

Permitted use
Use within the stated scope and preserve the next review trigger.
Classification confidence
High
Next control
Record the decision use, owner and review date.

Governance heuristic only. The state is not a probability, provider score or prediction of SEO performance.

A timestamp does not make evidence current.

SERPIFAI Evidence Freshness and Reliability Standard

How it works

Defensible query sample cycle covering objective, universe, inclusion criteria, adequacy validation and documentation.
Evidence quality depends on transparent sampling rules, adequacy checks and repeatable documentation as well as source freshness.

The evidence fitness gate

The standard uses one primary semantic model. Each material record moves through six controls before a governed state and permitted wording are assigned.

Evidence record → six controls → governed use

  1. Provenance

    Name who produced or observed the evidence and when the underlying observation was collected.

  2. Observation age

    Measure age from the observation—not the publication, upload or republishing date.

  3. Directness

    Distinguish direct observation from inference, synthesis and derivative estimates.

  4. Reproducibility

    Confirm another reviewer can inspect the record or repeat the method.

  5. Context fit

    Match buyer, offer, geography, device, language, market and decision stage.

  6. Decay risk

    Set a review window and event trigger based on volatility and decision consequence.

Current

Inside the review window, context-matched and not superseded.

Degraded

Still informative, but wording or decision use must narrow.

Stale

The review window expired or a material event invalidated current use.

Unresolved

Required evidence is missing or material contradictions remain unbounded.

ControlQuestionRequired record

Messy reality

Three sources disagree and the budget decision cannot wait

This composite failure pattern shows why the framework must separate the claim being made from the reputation or recency of each source.

7-day public pricing page £99 list price

Direct and current for advertised packaging.

14-day sales interview Negotiated enterprise terms

Direct qualitative evidence, but sampled and incentive-sensitive.

180-day tool cache £79 historical price

Derivative and stale for current pricing.

Controlled decision

Current: the public page can support a claim about advertised list pricing. Degraded: the sales interview can support a qualified statement that negotiated terms may differ. Stale: the cached historical price cannot support current pricing. Unresolved: actual realised deal terms remain unknown.

Pause

Pause any claim about realised deal terms or market-wide pricing.

Evidence request

Request permissioned contract, invoice or customer evidence matched to the target segment.

Escalate

Escalate when the budget decision depends on the unresolved price difference.

Stop

Stop the claim when no direct evidence can be obtained and the distinction is material.

Reopen

Reopen when pricing changes, a stronger record appears or the decision scope changes.

Founder design observation: when records disagree, the defensible output is often a narrower claim—not a forced winner.

How it is operated

Workflow, failure modes and decision boundaries

The default path stays compact. Open the advanced controls only when the decision is material, reviewers disagree or the evidence state is challenged.

Advanced six-stage workflow
  1. RecordCapture source, observed value, date, method and market context.
  2. ClassifyIdentify source class, directness and independence.
  3. TestCheck reproducibility, contradiction and context fit.
  4. Set decayAssign a review window and event trigger.
  5. Govern useLimit the claim to the decision the record can support.
  6. Refresh or retireUpdate, downgrade, supersede or preserve as history.
Common failure modes
Publication-date substitution

The article date is mistaken for the observation date.

Snapshot permanence

A single SERP or pricing capture is treated as a stable market condition.

Derivative recency

A recent page repeats an older estimate without adding evidence.

Unspecified decay

No review point is assigned to a fast-changing claim.

Source-brand substitution

A respected provider name replaces claim-level inspection.

Confidence collapse

Uncertainty is averaged into a score instead of being recorded separately.

Use, limits and stop condition

Use the standard whenever competitor evidence, SERP observations, tool estimates or first-party records influence classification, prioritisation or executive recommendations.

Do not use it as a universal provider score, automatic recommendation, causal test or performance forecast.

Pause when the accountable decision, material exclusions or minimum evidence requirement cannot be stated without contradiction.

Keep confidence separate from the evidence state. Confidence describes how secure the classification is; it does not change Stale evidence into Current evidence.

Where this framework hands off

Reviewer prompts

Questions reviewers should answer

Is recent evidence automatically reliable?

No. A recent record can still be derivative, irreproducible or context-mismatched. Freshness is one control inside evidence fitness.

Can older evidence remain usable?

Yes, when the underlying condition is stable, the context still matches, no superseding event has occurred and the record remains reproducible. The permitted wording must remain inside that boundary.

What happens when reviewers disagree?

Preserve both classifications and rationales, compare the exact claim and scope boundary, request the missing evidence and keep the state Unresolved until the conflict is bounded.

What should trigger reassessment?

A source correction, pricing or product change, new market entry, algorithm change, repeated anomalous observations, a stronger contradictory source, an expired review window or a changed decision context.

Evidence clockwork

Freshness × Change × Consequence

How to read it: select a checkpoint to isolate that part of the method. The canvas shows the relationship; the inspector explains what the checkpoint changes in the decision.

Decision useFreshness is decision-relative. Source age, rate of change and decision consequence combine to determine whether evidence can still be used without revalidation.

Evidence and method notes

W3C PROV-O provides a vocabulary for provenance records, while the UK AQuA Book frames analytical quality around robust, fit-for-purpose methods. Google Search Central provides context for helpful, reliable content and Article structured data. These sources inform the method; they do not certify the proprietary framework.
