SEO On-Page: Title Tag

Owns writing and review rules for the HTML <title> element. page-metadata owns discovery, implementation, and release verification.

Inputs

Read root contextus.md when present. Confirm page type, unique page job, primary search intent, locale, current title and H1, verified differentiators, sibling-page titles, and whether a template automatically appends the brand.

Rules

• Write a descriptive, concise, page-specific title that accurately represents the page.
• Put the primary search concept early when natural; do not keyword-stuff.
• Treat about 60 Latin characters for the title body as a default warning, not a hard limit. Pixel width, script, device, and query context affect display.
• A delimiter plus brand suffix such as | Brand is outside that title-body target. It may be truncated or rewritten; include it only when useful and never duplicate a template suffix.
• For CJK, RTL, or other scripts, review rendered width and natural language instead of applying a translated character formula.
• Title and H1 must serve the same page intent and promise, but need not use identical wording. Example: title AI Image Generator; H1 Generate Images with AI.
• Include only claims supported by the page. Do not add a year, number, superlative, or feature merely for click appeal.
• Apply the Swap Test: if the title fits a sibling page unchanged, add a verified page-specific fact or sharpen its task.
• Google may generate a different title link from the <title>, main visual title, headings, prominent text, anchors, og:title, or other signals. Optimize consistency of page identity, not control of the exact displayed string.

Cannibalization

When multiple URLs target the same primary intent, report the affected URLs, overlap, and evidence. Do not merge pages, reassign keywords, change page roles, or alter information architecture.

Output

• Recommended title, with the title body and optional brand suffix shown separately.
• A length or width warning when relevant, never a mechanical pass/fail.
• Brief rationale tied to intent and unique page facts.
• H1 semantic-alignment result; actual H1 edits route to heading-structure.
• Cannibalization warning when applicable.
