Scoring Model Version History
Only repository-backed history is published here. Unknown release details remain unknown.
Version policy
A scoring version records changes that can alter deterministic output. This includes a trigger, threshold, deduction, mode requirement, weight, tokenization rule, aggregation rule, severity boundary, or score band. Copy corrections that do not alter analyzer output do not create a new scoring version.
A version entry is published only when source, tests, fixtures, or a contemporaneous changelog retain enough evidence. Repository dates are not presented as public deployment dates.
SEO Blitz Scoring Model v2.0
| Model identifier | v2.0 |
|---|---|
| Model date in shipped source | August 2026 |
| Repository implementation evidence | First tracked v2.0 implementation found in commit 4543f9025a31cdabe9ad5515f6fead9fbdc6675b, committed 2026-08-04 |
| Dimensions | Clarity, Completeness, Structure, Readability, Specificity, Repetition, Title alignment, Publication readiness |
| Modes | Blog, Landing, Product, Local, Help, Comparison |
| Overall calculation | Rounded mode-weighted sum of eight clamped dimension scores |
| Finding presentation | Evidence-linked findings with three prioritized revisions |
The retained source changelog says v2.0 added six modes, an optional brief, eight dimensions, evidence-linked findings, and top-three prioritization. It also records the move to a mode-weighted overall score and eight breakdown cards.
The commit date proves the first tracked repository implementation found. It does not prove when v2.0 was deployed publicly.
Historical inline v1.1 implementation
| Version identifier | v1.1 |
|---|---|
| Date retained in current changelog | May 2026 |
| Repository evidence | An inline analyzer exists in the parent of commit 4543f9025a31cdabe9ad5515f6fead9fbdc6675b |
| Verified behavior | Word, sentence, paragraph, title, and reading-time metrics; one combined score; five breakdown cards; repeated-term output; keyword cloud |
The current embedded changelog describes v1.1 as a single-score model with five breakdown categories. No retained evidence supports earlier public claims about FAQ validation or a threshold change relative to v1.0.
v1.0 is not reproducible from retained evidence
No reproducible v1.0 implementation, fixture, or verified changelog entry was found in the inspected repository history. SEO Blitz therefore does not publish a v1.0 feature list, thresholds, weights, model date, or release date.
Current evidence gaps
- The first tracked v2.0 repository implementation is known. Its external production deployment date is not verified.
- The retained v1.1 inline engine has no dedicated frozen fixture in the current repository.
- No reproducible v1.0 engine was found.
Future change entries
Each future score-affecting change should identify its version, date, rule ID, previous behavior, new behavior, reason, expected effect, reproduction evidence, and implementation commit.
