Why this score?
Evidence ledger
css-for-js.dev currently scores 64/100. The score is being shaped by a mixed signal profile rather than one dominant factor. Evidence confidence is moderate, so the score should settle further after more crawl depth or registry checks. This is an estimated profile rather than a manually tracked one. Crawler access looks clean.

T
Trusted
79%
Strong trust, stability, and low-risk signals were detected.

Strongest tag heuristic
T · 79%
The highest raw tag match from the heuristic engine before visibility thresholds and manual overrides.
Trust score
71/100
Confidence derived from authority, crawl quality, stability, and risk signals.
Authority score
44/100
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
75/100
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
1/100
Lower is better. This reflects phishing, drainer, fake-support, fake-shop, and malware signals.
Infrastructure risk
3/100
Lower is better. This reflects the IP, registrar, and nameserver neighbourhood seen by the crawler.
Evidence confidence
52/100
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
91/100
Based on age, expiry runway, and the amount of ownership / registrar churn.
Registry & ownership
Domain age
5.8 years
Older domains generally carry more historical trust than very new ones.
Stability score
91/100
Penalised by registrar, ownership, and nameserver churn.
Days to expiry
86
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
3
Broader backlink evidence usually improves confidence.
Referring domains
3
Unique linking domains are more useful than raw link volume.
Organic keywords
74
Search footprint helps distinguish real sites from thin shells.
Indexed pages
41
Larger index coverage usually means more evidence to classify from.
Brand strength
62/100
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 · 91 ms
Slow or broken technical signals weaken confidence.
Content words
8,714
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
2 internal · 9 external
Link patterns help detect thin directories and promo pages.
Page speed / mobile
100/100 · 83/100
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
- Established domain age: 5.8 years.
