Zinn® SEO: Content analysis, part 2 of 2

What it does

• Accessibility checks — Heading order, links with no readable text or saying only "click here", missing or file-name alt text, untitled frames and tables without headers.
• Scores in the post lists — SEO and readability scores in every post list, sortable, with filters for needs work, no focus phrase, cornerstone and orphans, and a Content screen listing every page with what to fix.
• Duplicate finder — Pages that share an SEO title, a meta description or a main heading, across the whole site, found in the background.
• Pages competing for one phrase — Two pages with the same focus phrase are named in the editor and in the duplicate finder.
• Answer-readiness score (Pro) — How quotable a page is for AI answers and featured snippets: a direct answer up front, lists and tables, questions as headings, facts, sources, freshness and the author.
• Search intent and topic coverage (Pro) — The intent behind your phrase and whether the page's format serves it, and the subjects the pages that rank for it cover that yours does not.
• SEO revisions (Pro) — Every change to a page's SEO fields with who made it and when — from the editor, an import, WP-CLI or an AI agent — restored in one click.
