Top Priorities (5)

Sorted by impact
Critical: 1

3 button(s) with no accessible text

Buttons with no accessible text (icon-only, no aria-label) can't be activated by voice control or understood by screen readers.

Accessibility › Link & Button Quality
Critical: 2

No H1 heading found

No H1 means screen-reader users can't identify the page's primary topic, and Google's content-extraction degrades.

Accessibility › Heading Hierarchy
Warning: 3

1 render-blocking <script src> tag(s) without async/defer

Performance issues directly impact user engagement and conversion rates.

Performance › JavaScript Blocking
Warning: 4

No DMARC record found

Without DMARC, anyone can send phishing emails using your domain name.

Security › Email Security
Warning: 5

No SPF record found

Security gaps expose your site and users to attacks, eroding trust.

Security › Email Security
What fixing these means. Your site is in great shape. The remaining improvements are refinements rather than critical fixes. The 1 performance issue below shapes how fast users perceive your page. Addressing the critical issues below would have the most immediate impact on your audience reach.
2 accessibility issues exclude users who rely on assistive technology.
1 performance issue — Akamai's research found 53% of mobile users abandon pages over 3s.
2 security gaps detected — browsers may warn visitors about your site.
