notice No llms.txt for AI agents

Rule agent.llms_txt_missing · Agent Readiness · 1 occurrence(s)

notice Low text-to-HTML ratio

Rule content.low_ratio · Content · 7 occurrence(s)

notice Main text is hard to read (low Flesch Reading Ease)

Rule content.readability_poor · Content · 1 occurrence(s)

  • https://colerennerauthor.com/about/ — this page reads as difficult (Flesch Reading Ease 37, below 50) — long sentences and multi-syllable words make it hard to scan. Shorten sentences and prefer plainer words to widen your audience. Density can be legitimate for expert, technical or legal content, so judge it against who the page is for.

notice Likely hero image lacks fetchpriority=high

Rule images.hero_no_fetchpriority · Performance · 1 occurrence(s)

  • https://colerennerauthor.com/about/ — the likely hero/LCP image (logo_2_cole_renner.jpg) has no fetchpriority="high" — adding it tells the browser to fetch the hero earlier in the waterfall, reducing Largest Contentful Paint. This is a low-severity nudge; verify the flagged image is actually your LCP element.

notice Images without width/height (layout shift / CLS)

Rule images.missing_dimensions · Images · 7 occurrence(s)

notice Missing Open Graph tags

Rule og.missing · Social · 10 occurrence(s)

notice Legacy image format (jpg/png/gif) with no next-gen fallback

Rule perf.images_legacy_format · Performance · 1 occurrence(s)

  • https://colerennerauthor.com/about/ — 1 image(s) use a legacy format (jpg/png/gif) with no next-gen <picture> fallback. Serve WebP or AVIF (with a <picture> typed <source>) to cut image transfer weight and improve LCP.
