Google Spam Policy Check

Risk Level: High from last audit (4h ago)
low hidden_text_minor (3 occurrences)

3 element(s) with potentially hidden text — may be legitimate (accordions, tabs, screen reader text).

Recommendation
Review each element. Legitimate uses: tab content, accordions, skip-to-content links. Suspicious: keyword-stuffed paragraphs, hidden link lists.
Impact
Small amounts of hidden content for UI purposes are acceptable.
Policy: https://developers.google.com/search/docs/essentials/spam-policies#hidden-text-and-links
high hidden_links (1 occurrence)

1 hidden outbound link(s) detected — links with no visible text or CSS-hidden.

Code found:
http://willys-marine-diesel
Recommendation
Remove hidden links. Every outbound link should be visible to users with descriptive anchor text.
Impact
Hidden links are a definitive link spam signal. Google will penalize both the linking and linked pages.
