Why Duplicate Content Hurts SEO
Google penalizes pages with duplicate content by either filtering them from results or splitting ranking signals between copies. If your blog post shares 40%+ content with another page, neither page will rank as well as it could. This is especially common with AI-generated content — multiple tools given the same prompt often produce similar output.
How to Avoid Duplicate Content
Always edit AI drafts to add unique angles, personal experience, and original data. Use canonical tags when you intentionally syndicate content. Check your content against competitors before publishing.
