• Keyword in title, H1 (or the title, if the body has no H1), first 100 words, meta description and slug.
• Keyword use: flagged if absent or above about 3% of words (stuffing).
• Title 30-60 characters; meta description 70-160 characters.
• Length: 300 words minimum, 800+ for a full guide. At least two H2 subheadings, no skipped heading levels.
• Readability: Flesch reading ease (60+ is plain English). Shorter sentences and words raise it.
