Frequently Asked Questions
What originality score should I aim for?
Aim for 90%+ originality for any content you publish. Below 80% indicates significant rewording of existing content, which can harm your SEO if detected.
Will Google penalize me for duplicate content?
Google does not technically penalize duplicate content unless it is clearly intended to manipulate rankings. However, duplicate content may be filtered from results, causing pages not to rank. Always create original content.
