Our 4-Step Checklist Before Publishing AI-Generated Content
To ensure your AI blog posts pass Google’s Helpful Content guidelines and drive genuine conversion, follow this protocol:
- Inject Original Experience (E-E-A-T): Add personal anecdotes, original screenshots, or unique benchmark data that an LLM could never know.
- Fact-Check Every Numeric Claim: Verify dates, tool pricing, and statistics against official documentation.
- Trim Fluff & Robotic Idioms: Search and remove repetitive AI cliches like “In today’s fast-paced digital landscape” or “Delve into”.
- Run a Plagiarism Scan: Ensure the synthesized phrasing is 100% unique.
