Real examples by format

What good looks like — for each content type.

Real, well-known articles that exemplify each format. Study the structure, not just the topic — the lede shape, the schema, the internal linking, the citation footprint. These are the patterns AI surfaces are rewarding.

Comparison
Head-to-head evaluations. "X vs Y", "best X for Y".
Strongest on Perplexity & ChatGPT — especially in B2B SaaS and Fintech.
  • Stripe
    Stripe vs Square

    Declarative verdict in the lede. Side-by-side feature table. Pricing matrix at the bottom.

  • Linear
    Linear vs Jira

    Owns the comparison framing. Explicit feature differentiation. Cited by ChatGPT for project-tracking queries.

  • G2
    Notion vs Airtable

    Structured user-rating data + feature-by-feature breakdown. The model can extract any cell directly.

Listicle
Numbered or bulleted lists of options in a category.
Dominant on Google AI Overviews (41% share) and Gemini.

Step-by-step procedural content. Often HowTo-shaped.
Strongest on Claude (24%) and DevTools (28% on ChatGPT, 31% on Claude).
Explainer

Dominant on Claude in AI tools (27%) and Healthcare (36%).
Case study
A specific customer or scenario walked through with outcomes.
Strongest on Claude (11–15% in B2B SaaS, Healthcare). Underused everywhere else.
