Each cached page has two scores from 0 to 100: What bots get (the HTML Jazui serves, with your rules applied) and Original site (the page as the browser paints it, before rules). The difference tells you how much Jazui improves your page. It's audited on every render; checks that need the network run in the background and site-wide checks run hourly.
The score window has Fix first (each problem with the points gained by fixing it), one tab per category, the Google and sharing Preview, and the change History.
Calculation
Each check comes out Good (full weight), Warning (half) or Error (nothing). Each category scores from 0 to 100 and the total is the weighted average:
| Category | Weight |
|---|---|
| Metadata | 25 |
| Content | 20 |
| Social | 15 |
| Structured data, Links, Images and Technical | 10 each |

Raising the score without touching your code
- Missing title, description, Open Graph or structured data: an Inject into <head> rule, or ask your AI to suggest them and apply them as a rule in one click.
- The page is slow or saved incomplete: raise the maximum time or use a page-ready selector.
- Banners or chats cluttering the content: a Remove elements rule.
- Anything that depends on your HTML (H1, alt text, internal links) is best fixed on your website.
