Calculator
Enter page-level or site-level metrics. The calculator converts raw inputs into normalized factor scores, applies weights, subtracts penalties, and returns a final SEO optimization score.
Example Data Table
| Scenario | Title Length | Meta Length | Word Count | Load Time | Mobile Score | CWV Pass | Broken Links | Final Score |
|---|---|---|---|---|---|---|---|---|
| Blog Article | 57 | 154 | 1450 | 2.1s | 96 | 91% | 0 | 88.6 |
| Service Page | 49 | 146 | 860 | 3.4s | 90 | 76% | 2 | 73.4 |
| Product Page | 63 | 138 | 620 | 4.6s | 82 | 62% | 4 | 58.9 |
Formula Used
Factor Score = Normalized score from each raw metric, scaled from 0 to 100.
Weighted Points = Factor Score × Factor Weight ÷ 100.
Base Weighted Score = Sum of all weighted points.
Broken Links Penalty = Minimum of 12 or Broken Links × 1.5.
Crawl Errors Penalty = Minimum of 10 or Crawl Errors × 2.
Duplicate Content Penalty = Minimum of 12 or Duplicate Content % × 0.20.
Final SEO Optimization Score = Base Weighted Score − Broken Links Penalty − Crawl Errors Penalty − Duplicate Content Penalty. The final value is capped between 0 and 100. Higher scores indicate better readiness for visibility, usability, and crawl efficiency.

- Enter values for content, headings, metadata, speed, usability, authority, and technical health.
- Click the calculate button to generate the score, grade, category breakdown, and weighted factor table.
- Review the penalty section carefully because technical problems can sharply reduce an otherwise decent score.
- Use the recommendations list to decide which fixes should happen first, then recalculate after improvements.
FAQs
1. What does this calculator measure?
It combines on-page, technical, usability, and authority signals into one weighted score. The result highlights current strengths, weak areas, and likely improvement priorities for organic performance.
2. Is a score of 100 possible?
Yes. A perfect score needs strong inputs across content, indexing, speed, structure, and usability, with no penalties from broken links, crawl errors, or duplicate content.
3. Can I use it for a single page?
Yes. It works well for a single landing page, article, service page, or product page. Use page-level metrics instead of sitewide averages whenever possible.
4. How often should I recalculate?
Recalculate after major content edits, technical fixes, speed work, template changes, or link-building campaigns. Monthly checks also help track optimization progress over time.
5. Does it replace a full SEO audit?
No. It is a prioritization tool, not a full audit. It summarizes important signals quickly, but detailed crawling, log analysis, and competitor research still matter.
6. Why are penalties shown separately?
Penalties make visible how broken links, crawl issues, and duplicate content drag results downward, even when weighted factor scores look respectable.
7. What score is considered good?
Many pages become competitive above 75, strong above 85, and excellent above 90. The right target still depends on industry difficulty and competitor quality.
8. Which inputs matter most?
Content quality, title relevance, speed, mobile usability, Core Web Vitals, indexability, and backlink quality usually move the score the most because they carry heavier weights.
