Performance

Google treats LCP over 4 seconds as poor. The usual causes are an oversized hero image, render-blocking CSS, or a slow server response.

Technical

External links

Investigate if too many external links might dilute SEO or hamper user focus.

Technical

3

Heading length

The recommended H1 length is from 20 to 70 characters

Other crawl findings

Pagination loops can trap crawlers. Fix rel=prev/next implementation.

Technical

5

Mobile

1

Readability

Simplify language to improve user experience & accessibility.
