Tag intelligence
Trusted (76% match) because low spam indicators plus strong trust, quality, registry, and stability signals were detected.
T
Trusted
76%
Strong trust, stability, and low-risk signals were detected.
Heuristic: The site shows a reasonably trustworthy and stable profile.
Why: Low spam indicators plus strong trust, quality, registry, and stability signals were detected.
Strongest tag heuristic
T · 76%
The highest raw tag match from the heuristic engine before visibility thresholds and manual overrides.
Trust score
56/100
Confidence derived from authority, crawl quality, stability, and risk signals.
Authority score
36/100
A higher authority score usually means broader reputation and backlink confidence.
Spam risk
0/100
Lower is better. This blends spam indicators with false-positive protections for legitimate sites.
Quality score
93/100
Based on crawl quality, content completeness, and technical evidence.
Safety score
100/100
Higher is safer. Direct fraud signals can heavily cap this even when SEO signals look strong.
Fraud score
0/100
Lower is better. This reflects phishing, drainer, fake-support, fake-shop, and malware signals.
Infrastructure risk
1/100
Lower is better. This reflects the IP, registrar, and nameserver neighbourhood seen by the crawler.
Evidence confidence
91/100
Higher means the crawler had enough pages and registry evidence to make a stronger call.
External evidence
Low
Quality of the structured search and review evidence cluster.
External decision
Inconclusive
How third-party evidence compares with the current candidate tag.
NSFW score
0/100
Context-aware adult-content detection with medical / educational false-positive reduction.
Registry stability
100/100
Based on age, expiry runway, and the amount of ownership / registrar churn.
Registry & ownership
Domain age
—
Older domains generally carry more historical trust than very new ones.
Stability score
100/100
Penalised by registrar, ownership, and nameserver churn.
Days to expiry
—
Very short renewal windows can be a weak trust signal.
Registrar / ownership changes
0 / 0
Frequent ownership churn can weaken trust.
Nameserver changes
0
Repeated infrastructure changes can indicate instability.
DNSSEC / privacy
DNSSEC off · privacy off
DNSSEC strengthens DNS trust; privacy is neutral on its own.
Reputation & search evidence
Backlinks
0
Broader backlink evidence usually improves confidence.
Referring domains
0
Unique linking domains are more useful than raw link volume.
Organic keywords
82
Search footprint helps distinguish real sites from thin shells.
Indexed pages
463
Larger index coverage usually means more evidence to classify from.
Brand strength
72/100
Stronger brand signals reduce false positives for legitimate sites.
Risk label
GOOD
This is the raw crawl / heuristic risk label feeding the tag model.
Crawl, content & technicals
HTTP status
200
Healthy responses make classification more reliable.
HTTPS / speed
HTTPS OK · 1,116 ms
Slow or broken technical signals weaken confidence.
Content words
945
Thin pages are harder to trust and easier to manipulate.
Schema / structure
0 schema · meta · H1
Structured markup and basic on-page hygiene improve quality confidence.
Links on page
72 internal · 8 external
Link patterns help detect thin directories and promo pages.
Page speed / mobile
69/100 · 82/100
Better technical quality generally reduces low-effort site patterns.
Crawl access
Open
The crawler reached the site without an anti-bot challenge.
External evidence & explainability
Decision state
Inconclusive
Structured third-party evidence is still too thin, mixed, or unqualified to force a harder verdict.
Evidence quality
Low
Blends source trust, domain matching, evidence diversity, and freshness.
Support vs contradiction
0 / 0
Compares how much structured external evidence supports the candidate tag against evidence that contradicts it.
Qualified risk sources
No
Risk tags only promote from external evidence when source diversity or source trust thresholds are met.
Uncertainty buffer
Clear
Prevents thin or mixed external evidence from forcing a stronger tag than the evidence can justify.
Positive signals
- Low registrar / ownership churn with solid registry stability.
- Healthy crawl quality and on-page completeness.
- Search evidence is broad enough to classify with better confidence.
Risk signals
No major risk cluster stood out from the current crawl.
