SEO Checklist

SEO Checklist is a 20-item audit checklist covering Meta, Social, International, Content, Accessibility, Technical, Performance, Rich Results, and UX categories. Each item has a short label and a concrete description (for example, Title Tag is described as a unique title tag of 50-60 characters on every page). Your checked state is persisted across sessions through the project's local tool-data store.

1. Read the progress bar at the top, which shows done / total and a percentage based on how many items you have checked. 2. Work through the category cards; each item has a checkbox, a bold label, and a one-line description explaining the audit criterion. 3. Tick items as you complete or verify them; the progress bar and counter update immediately and the state is saved to local storage. 4. Checked items are visually struck through so you can quickly see what remains open at a glance.

Meta: Title Tag, Meta Description, Canonical URL. Social: Open Graph Tags, Twitter Card Tags. International: Hreflang Tags. Content: H1 Tag, Heading Hierarchy, Internal Links.
