How this rule is weighted

Importance
3 / 10
How much this matters relative to other rules.
Confidence
SPECIFICATION
A standard says so: HTML, WCAG, an RFC or Google's own documentation.
Severity
info
How the finding is presented when it fails.
Scoring
Excluded
Reported in the report, never penalised.

Impact is importance multiplied by the confidence tier’s weight — SPECIFICATION 1.0, RESEARCH 0.7, EMERGING 0.3, EXPERIMENTAL 0.1. Two rules backed by the same class of evidence therefore always carry the same weight, which is what makes the score reproducible rather than hand-tuned.

Questions about this rule

Does HTML_INPUT_TYPE_VALID affect my score?
No. It is a detection rule: it runs, appears in your report and never penalises you. "Inputs use semantic types" is information about the page rather than a defect - most pages are not expected to satisfy it.
What does SPECIFICATION confidence mean?
A standard says so: HTML, WCAG, an RFC or Google's own documentation. Confidence is a declared tier rather than a per-rule number, so every rule backed by the same class of evidence carries the same weight - which is what makes the score reproducible instead of hand-tuned.
How do I check HTML_INPUT_TYPE_VALID on my own site?
