Two different jobs people call “Claude SEO tool”
Searchers looking for the best Claude SEO tool usually mean one of two things: a Claude Code skill/plugin that audits or writes SEO advice inside the chat, or a product that scores plugins and websites over time with history and peers.
Mixing those jobs creates bad buys — a skill that writes meta descriptions will not schedule Core Web Vitals, and a monitoring product will not replace an in-editor SEO skill.
When a Claude SEO skill is enough
You need a one-off technical pass, content outline, or schema draft on a URL you paste in. You already live in Claude Code. You can judge output quality yourself.
Then compare skill suites on evidence and coverage — not skill-count marketing. Use a fixed test URL and planted defects.
When you need a scheduled audit platform
You publish Claude plugins and care about context cost and permissions after each release. You want competitor website audits on a cadence. You need ranked “fix first” items your team can ship without re-prompting every Monday.
That is AuditHQ’s lane: free scores, saved projects, schedules, and Pro diagnosis — including Claude plugin audits and competitor website compare on audithq.app.
A practical pick
Use both when you can: a Claude SEO skill for drafting, AuditHQ for measuring what shipped. If you only pick one “best Claude SEO tool” for plugin authors, start with a published-surface audit so install trust and token cost are visible before you add more skills.
