What to fix first
View all priorities →Includes issues from the extended diagnostic report.
- Fix 4 diagnostic broken links
Start with navigation and internal links so visitors can reach your pages.
- Heading hierarchy
Nest headings logically without skipping a level, starting with H1.
- Image dimensions declared
Declare width and height attributes (or an inline aspect-ratio style) on every visible <img> so the browser reserves space before the image loads. Reference: web.dev / Lighthouse "image elements have explicit width and height" (layout shift).
Fix with your coding assistant
Copy a ready-to-use prompt with the issues and affected URLs.
Your path to S-Tier
Not yet S-TierHealthy links, every scored requirement passed, and complete evidence in the selected sample.
- Revalidate the badge with a new scan (valid for 30 days).
- Pass all scored quality requirements across the five categories.

Measured findings to investigate, ordered by audit score.
1. Forced reflow
A forced reflow occurs when JavaScript queries geometric properties (such as `offsetWidth`) after styles have been invalidated by a change to the DOM state. This can result in poor performance. Learn more about [forced reflows](https://developer.chrome.com/docs/performance/insights/forced-reflow) and possible mitigations.
2. Elements with visible text labels do not have matching accessible names.
Visible text labels that do not match the accessible name can result in a confusing experience for screen reader users. [Learn more about accessible names](https://dequeuniversity.com/rules/axe/4.13/label-content-name-mismatch).

3. Document does not have a meta description
Meta descriptions may be included in search results to concisely summarize page content. [Learn more about the meta description](https://developer.chrome.com/docs/lighthouse/seo/meta-description/).
4. Heading elements are not in a sequentially-descending order
Properly ordered headings that do not skip levels convey the semantic structure of the page, making it easier to navigate and understand when using assistive technologies. [Learn more about heading order](https://dequeuniversity.com/rules/axe/4.13/heading-order).

5. Network dependency tree
[Avoid chaining critical requests](https://developer.chrome.com/docs/performance/insights/network-dependency-tree) by reducing the length of chains, reducing the download size of resources, or deferring the download of unnecessary resources to improve page load.
6. Largest Contentful Paint
Largest Contentful Paint marks the time at which the largest text or image is painted. [Learn more about the Largest Contentful Paint metric](https://developer.chrome.com/docs/lighthouse/performance/lighthouse-largest-contentful-paint/)
7. Time to Interactive
Time to Interactive is the amount of time it takes for the page to become fully interactive. [Learn more about the Time to Interactive metric](https://developer.chrome.com/docs/lighthouse/performance/interactive/).
8. First Contentful Paint
First Contentful Paint marks the time at which the first text or image is painted. [Learn more about the First Contentful Paint metric](https://developer.chrome.com/docs/lighthouse/performance/first-contentful-paint/).

Battle scoring rules
The arena winner follows the verified ranking: internal link health first, then the published two-decimal quality score. Both sites need two agreeing standard observations. Browser performance, accessibility and SEO are complementary diagnostics and do not move the ranking or decide its winner. Page-only battles compare compatible rounds; performance differences up to five points draw, and equal round wins remain a tie. Missing measurements never count as zero. Browser audits do not certify accessibility. Saved results keep their measured evidence; start a rematch for a newer comparison.
