Formula Used

The calculator uses a weighted scoring model. Each section receives a normalized score from 0 to 100. The final grade is the sum of each subscore multiplied by its weight.

Overall SEO Score = (Title × 0.10) + (Meta × 0.08) + (URL × 0.06) + (Content × 0.12) + (Density × 0.08) + (Headings × 0.08) + (Links × 0.07) + (Images × 0.07) + (Keyword Placement × 0.12) + (Technical × 0.10) + (Performance × 0.08) + (Readability × 0.04)

Technical and keyword-placement checks are converted into points from yes or no inputs. Performance blends page speed and mobile usability. Image scoring uses alt-text coverage. Heading, title, meta, URL, and density scores are graded against practical target ranges.

FAQs

1. What does this calculator measure?

It estimates on-page SEO quality using title, meta, content depth, keyword placement, links, images, technical checks, readability, and performance inputs.

2. Is this a live crawler?

No. It is a planning and auditing calculator. You enter page values manually, then the script converts them into a weighted grade.

3. Why is the score weighted?

Some signals affect page quality more than others. Weighted scoring helps balance content relevance, technical health, and user experience in one result.

4. What is a good SEO score?

A score above 80 is strong for this model. Pages below 60 usually need meaningful improvements in content, structure, or technical setup.

5. Does keyword density guarantee rankings?

No. Keyword density only helps this model check natural topical usage. Rankings depend on many factors, including intent satisfaction and competition.

6. Why does alt text matter here?

Alt text improves accessibility and helps describe important images. Better coverage can support page quality and user experience.

7. Can I change the scoring weights?

Yes. Edit the weight values inside the score formula section of the script to match your own audit framework or content standards.

8. What should I improve first?

Start with missing basics: title, meta, H1, indexing, HTTPS, mobile usability, speed, content depth, and keyword placement in key locations.
