- Counts
- A failure costs points in its category.
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 SEO_TITLE_EXISTS affect my score?
- Yes. It is an importance 10 rule at SPECIFICATION confidence, so a failure costs 10 × 1 points of impact in the SEO category before that category is normalised to 100.
- 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 SEO_TITLE_EXISTS on my own site?
- Paste your URL into the box above and it runs only this rule, usually in a couple of seconds. It is also included in the SEO checker and in a full scan.
