Why AI-Generated SEO Content Is a Liability

Google can demote AI-detected content, clients audit articles with Originality.ai, and editors flag AI-shaped prose. SEO writers need a rewriter that protects rankings without breaking keywords.

Originality.ai is the industry standard

Most agencies and publishers now run Originality.ai on every freelance article. A high AI score gets your invoice rejected.

Generic paraphrasers strip your keywords

Quillbot and free spinners often replace your target keywords with synonyms — wrecking on-page SEO in the process.

Re-running ChatGPT does not fix the score

Asking ChatGPT to 'rewrite for SEO' leaves the AI fingerprint intact. Originality.ai still flags it.

StealthGPT only changes writing patterns — keyword density, headings, and topical relevance are preserved. In our testing, rewritten articles maintain ranking positions or improve due to better readability.

How well does it score on Originality.ai?

Most users see Originality.ai scores drop from 90%+ AI to under 10% AI after using Aggressive mode. Some long-form articles need a manual cleanup pass for the strictest results.
