Platform-Based Content Writing Strategies

Writing Content for ChatGPT

ChatGPT is tied to training data cycles; content you write today may be effective in the next model update. For this reason, evergreen, in-depth, and authoritative content should be prioritized.

Format recommendations: Question-format titles ("What is X?", "How to do X?"); Structure: Introduction → Definition → Steps/Comparison → FAQ → Conclusion; Length: 1000-1500 words; Statistics: 1-2 sourced statistics every 400 words; Schema: Organization + Article (required), FAQPage (recommended).

Content types ChatGPT likes: "What is X?" definition guides; "X vs Y" comparison articles; "How to do X?" step-by-step guides; Industry trends and forecast articles.

What ChatGPT dislikes: Purely promotional content; Claims without statistics or sources; Short content under 400 words.

Writing Content for Gemini

Gemini works integrated with Google's search ecosystem. Google SEO standards + E-E-A-T signals directly affect Gemini visibility.

Format recommendations: Structure: Bullet list + table heavy; Length: 700-1100 words (Gemini prefers concise content); Author schema: Author name + area of expertise + LinkedIn/source link; Schema: FAQPage + HowTo (Gemini displays these formats as snippets).

Content types Gemini likes: Step-by-step guides (numbered list format); Comparison tables; Local service content (supported with GBP); E-E-A-T strong expert articles.

What Gemini dislikes: Outdated content (dateModified missing); Content without author information; Mobile-incompatible page structure.

Writing Content for Perplexity
