Fix these first
- H1 headingcritical
No H1 heading.
Fix: Use one H1 that states the page topic with its main keyword.
On WordPress: Most themes show the page title as the H1. In the editor, make sure no other block uses Heading 1 – use Heading 2 for sections.
- Canonical URLhigh
No canonical tag.
Fix: Add <link rel="canonical" href="(this page's full URL)"> – only point it elsewhere for true duplicates.
- Entity clarityhigh
No Organization / LocalBusiness structured data – search engines and AI have to guess who runs this site.
Fix: Add Organization or LocalBusiness JSON-LD with name, url, logo, contact details and sameAs links to your official profiles.
- JSON-LD present & validhigh
No JSON-LD structured data.
Fix: Add JSON-LD describing the business and the page (Organization/LocalBusiness, WebSite, WebPage or Article, BreadcrumbList).
- Server response (TTFB)high
1834 ms until the first response from our checker, including connection setup (Google rates TTFB good under 0.8 s, poor over 1.8 s).
Fix: Use page caching or a CDN (e.g. Cloudflare) so HTML is served from the edge.
- Render-blocking resourceshigh
2 blocking script(s) and 3 stylesheet(s) in <head>.
Fix: Add defer to scripts, inline critical CSS and load the rest asynchronously.
- HTTPScritical
1 file(s) load over insecure http:// (mixed content) – browsers may block them.
Fix: Serve everything over HTTPS and update http:// file links.
On WordPress: Ask your host to turn on a free SSL certificate, then in Settings → General change both addresses to start with https://.
- Mobile viewportcritical
viewport: width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0 – blocks pinch-zoom
