A page should have exactly one <h1>. This page has four — a common bug from template composition where header/hero/section/footer components each use H1. Google can't tell which one represents the page topic.
Hero section content. The H1 above is set by the hero component.
The featured section component also uses H1 instead of H2.
The sidebar widget developer used H1 too.
And the footer CTA component picked H1 because "it stood out best".
