🔍 Why Originality Matters for SEO
🚨
Google's Panda algorithm specifically targets thin and duplicate content — it can suppress your entire site.
🏆
Only one version of duplicate content will rank. If yours isn't the original, Google won't show it.
🔗
Backlinks pointing to copied content provide no SEO benefit — links only work for original pages.
✍️
Rewrite, add context, and include your own analysis — even referencing others requires original commentary.
📊
Aim for 90%+ originality on all published content — especially on competitive keywords.
