site.duplicate-content

What to change

A finding of this rule on a page carries the exact edits for that page: the markup it quotes, and what to write instead.

When it runs

Runs on a crawl or a build directory. A warning is a problem that costs a page ranking, clicks or citations. Each finding takes 5 points off the page's score.

The severity here is the rule's usual one: a finding can be raised or lowered when the page gives a reason.

Run it, or skip it

Check a page for this rule alone, after a fix for instance:

npx @rivi-software/agentic-seo-check crawl https://example.com --rule site.duplicate-content

Or from an assistant, with the MCP tool seo_crawl_site:

{
  "url": "https://example.com",
  "rules": [
    "site.duplicate-content"
  ]
}

To leave it out of an audit, pass --disable site.duplicate-content on the command, or disableRules: ["site.duplicate-content"] to a tool.
