How it works
The free version lets you run occasional checks from the homepage, while Copysentry watches your site automatically and emails you when new copies appear. Copyscape Premium works the other way round: you check a piece of writing before publishing to see whether it matches anything already on the web, which is useful for editors reviewing freelance work.
Copyscape is deliberately narrow — it does one job, finding copied text, and does it well. It is not a full SEO suite, so it pairs best with a rank tracker or site auditor. For anyone whose content is their business asset, the monitoring plans are a cheap form of protection.
