Rule duplicate.title · Duplicate · 11 occurrence(s)

warning Missing <h1>

Rule h1.missing · Headings · 1 occurrence(s)

warning Hero/LCP image is lazy-loaded (loading=lazy delays LCP)

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

  • https://www.lifesciencetextbook.com/about-us-25 — the likely hero/LCP image (discoveringlifescience_front(6).jpg) has loading="lazy" — Google explicitly warns against lazy-loading the LCP image, because it delays the fetch until layout completes.

warning Product schema missing required or recommended properties

Rule schema.product_incomplete · Structured Data · 1 occurrence(s)

  • https://www.lifesciencetextbook.com/product-page/sample-product — Product structured data is missing required properties (offers.price, offers.priceCurrency) — without them Google won't generate the rich result.
