Zinn® SEO: Site authority

What it does

• Your Ahrefs Domain Rating, free — Paste a free Ahrefs key and watch your Domain Rating inside WordPress, with its history and an e-mail when it moves. No paid Ahrefs plan needed.
• Zinn® Authority, pay as you go — No SEO tool account? See your authority score, referring domains and spam score from Zinn®'s own backlink data, a few cents a check.
• Pick the scores that matter to you — Choose which scores sit on your dashboard and which are kept with history and alerts, from every source you connect.
• Every score's history — See how each score moved day by day, week by week or month by month, and download it as a spreadsheet.
• Told when a score goes up or down — Set the change you care about, like Domain Rating dropping 3 points or Spam Score passing 30, and hear about it by e-mail and inside WordPress.
• Checks on your schedule, cost shown first — Daily, weekly or monthly checks that use your own allowance with each tool, shown before you save. If your allowance runs out they pause and carry on by themselves.
• Bring the SEO tools you already pay for (Pro) — Connect your own Ahrefs, Majestic, Moz, Semrush or SE Ranking account and see Domain Rating, Trust Flow, Domain Authority and more for your site. Your keys stay safe with Zinn, never in WordPress.
• See how you compare (Pro) — Track up to ten competitors on the same scores and see their history next to yours.
• Every client site in one table (Pro) — Agencies see every connected site's scores and changes in one table in their Zinn® account.
• Scores in your client reports (Pro) — Your white-label reports show each site's authority scores and how they moved, credited to the tool that measured them.
