Audit Results

Analytics 3 signals
  • Google Analytics No Google Analytics detected. Without analytics you can't measure traffic or conversions.
  • Google Tag Manager No GTM detected. Optional — only worth adding if you run many tracking pixels.
  • Facebook Pixel No Facebook Pixel detected. Optional — only worth adding if you run Meta ads and need retargeting.
Mobile 2 signals
  • Mobile Viewport Viewport missing width=device-width — mobile experience will be subpar.
  • Flash Content No Flash content — good, Flash has been discontinued since 2020.
Onpage 18 signals
  • Title Tag Title is only 9 characters. Aim for 50–60 characters to maximize SERP display without truncation. Use our Meta Tag Generator →
  • Meta Description Description present, 130 characters — within the sweet spot.
  • Meta Keywords No meta keywords tag present — this is modern best practice. Google ignores this tag since 2009.
  • H1 Heading Exactly one H1 on the page: "Wikipedia The Free Encyclopedia"
  • Heading Hierarchy Logical heading structure: H1:1 H2:5 H3:1 H4:0 H5:0 H6:0.
  • Image Alt Text All 1 images have alt text. Excellent for accessibility and SEO.
  • Internal vs External Links 0 internal, 374 external. Internal link ratio is low (0%). Consider linking more to your own content.

  • Custom 404 Page Missing URLs return a full 404 response (2,020 bytes). Visitors get proper feedback.
  • W3C HTML Validity 34 W3C HTML errors. Worth cleaning up — most are usually 3rd-party scripts or non-standard attributes.
  • Text to HTML Ratio Text/HTML ratio: 56.6% — healthy content-to-markup balance.
  • Total Link Count 374 links on page.
  • Author Meta No author meta tag. Optional — relevant for blogs and news sites.

Performance 12 signals
  • HTTP Status Server returned HTTP 200.
  • Response Time Fast TTFB: 200ms. Well under Google's 800ms target.
  • Page Size Page weight: 30 KB. Lightweight — good for mobile users on slow connections.

  • Browser Caching Static asset https://wikipedia.org/static/apple-touch/wikipedia.png caches well: max-age=31536000.
  • HTTP Version Serving over HTTP/2 — multiplexed and modern.
  • External Resources 0 CSS + 2 JS external files — reasonable.
  • Inline <style> Tags 3 inline style blocks. A small amount can be fine (critical CSS), but keep it minimal.
  • Inline <script> Tags 2 inline scripts. A few are fine; externalize if you can for caching benefits.
  • Iframes No iframes — keeps load time predictable.
  • Image Count 1 images.
