Quick Comparison Table: SEO vs. AEO

Good vs. Bad: AEO Practices in 2025

Lead with the Answer:
Place your core answer at the top of every article or FAQ ,skip the lengthy preamble.

Break Content into Digestible Chunks:
Structure content with clear H2 and H3 headings formatted as questions. This helps AI systems parse and extract information efficiently.

Implement Structured Data:
Use schema markup (FAQ, Product, HowTo, Review) to tag key content elements for better AI recognition.

Establish Credibility:
Display author credentials, reference authoritative sources, and keep content fresh with visible update dates (e.g., “Last Updated: August 2025”).

Create Original Research:
Develop unique data points, case studies, or statistics that AI models like Gemini, ChatGPT, and Perplexity will want to reference.

Use Structured, Skimmable Sections:
Organize content using question-based headings (H2/H3) to make it easy for AI to identify and extract relevant segments.

Write Conversationally:
Craft responses as if you're having a real dialogue—natural language resonates with both AI systems and human readers.

Adopt a Human Tone:
Write as though you're answering a friend’s question. Authenticity improves both AI comprehension and user engagement.

Bad AEO Practices

Keyword Stuffing:
Repeating target keywords in unnatural ways throughout your content. AI language models are sophisticated enough to detect and disregard this manipulative, mechanical writing style.

Wall-of-Text Syndrome:
Publishing long, unbroken paragraphs or extended introductions that force readers (and AI) to hunt for the actual answer you're trying to provide.

Absent Schema Implementation:
Failing to add structured data markup to your FAQs, product information, or instructional content means AI crawlers may overlook key details when generating answers.

Question-Averse Headers:
Relying exclusively on traditional, corporate-style section names like “Our Offerings” or “Company Background,” instead of formatting headers as direct questions that match search intent.

Missing Credibility Signals:
Publishing content without visible author information, credentials, or cited sources—a red flag that causes AI platforms to lower your content’s authority and trustworthiness.

Static, Unrefreshed Content:
Leaving content untouched for months or years. AI systems prioritize recently updated, actively maintained information when selecting sources for AI Overviews and citation-based responses.
