  Time to First Byte (TTFB)

  Time to First Byte is 51492 ms (51.49 sec) — Google flags this as "poor" (> 1.8 s per web.dev/articles/ttfb). The browser cannot begin rendering until the first byte arrives, so LCP cannot beat 51.49s. Every downstream Core Web Vital (LCP, INP, CLS) inherits this delay, and Page Experience signals trigger a soft demotion in Google + Bing rankings.

  FAIL · ai-readiness

  Structured Data Completeness

  No structured data (JSON-LD / Schema.org) found. AI search engines rely heavily on structured data to understand and cite content. Without it, your pages are much less likely to appear in AI-generated answers.

  Indexability

  Canonicalized to another URL — <link rel="canonical"> points to a different URL: https://www.hubspot.com. Search engines will index that URL, not this one.

  FAIL · performance

  Page Size

  The total HTML page size is 607.5 KB, which significantly exceeds the recommended limit of 100 KB. Heavy pages load slowly, especially on mobile devices and slow internet connections. This negatively impacts Core Web Vitals and search rankings.

  Browser Caching

  Only 1 out of 4 caching headers found (Cache-Control). Missing: Expires, ETag, Last-Modified. Caching is virtually unconfigured, causing resources to be reloaded on every visit.

  Knowledge Panel Readiness

  Partial knowledge-panel readiness — score 50/100. Missing components: Organization JSON-LD with ≥5 sameAs anchors, visible NAP (name/address/phone). Each missing piece reduces the chance of appearing in Google Knowledge Panel and AI-search citation anchors.

  Render-Blocking Resources

  Found 26 render-blocking resources (24 CSS, 2 JS) — this is too many. The browser must download and process all of these files before it can start rendering the page. This critically delays First Contentful Paint (FCP) and Largest Contentful Paint (LCP).

  Security Headers

  Found 5 out of 6 modern security headers. Missing: permissions-policy. Add the remaining headers to close defense-in-depth gaps. Note: Content-Security-Policy is the highest-impact header — if it is missing the site is exposed to XSS even when other headers are present.
