The complete guide to Answer Engine Optimization.

AEO (Answer Engine Optimization) is the new SEO. Here's exactly how to get your brand cited by ChatGPT, Perplexity, Gemini, and Google AI Overviews in 2026 — with the same playbook I use for clients.

Four overlapping acronyms, one strategy. Here's what each term actually means, where they overlap, and which one your team should be talking about.

Inside ChatGPT, Perplexity and Google AI Overviews: the retrieval, ranking and trust signals that decide which brands get named in an answer — and which ones don't.

Featured Snippets quietly died in 2025 — replaced almost everywhere by AI Overviews. The optimization playbook is different in five specific ways. Here's the side-by-side and what to fix on your top pages this quarter.

Each AI engine cites differently — different bias toward freshness, different schema preferences, different source trust signals. Here's where to focus first based on your audience.

FAQPage, Article, Organization, Person, Product — here's the precise schema stack that gets pages cited by ChatGPT, Perplexity, and Google AI Overviews.

What llms.txt is, why ChatGPT and Perplexity care, and exactly what to put in yours — with a copy-paste template you can ship today.

Wikidata, sameAs, knowledge graph, NAP consistency — the entity signals that turn your brand from a string into a citable entity.

On-page schema is half the battle. The other half is entity stacking — the off-page work that makes LLMs confident your brand is who you say you are. Here's the full playbook.

Backlinks correlate with rankings. Unlinked brand mentions — and how fast they're accumulating — correlate with AI citations. Here's how to build the velocity flywheel.

The full playbook for taking a B2B brand from zero entity authority to a recognized entity across Wikidata, Crunchbase, Knowledge Panel, and ultimately Wikipedia — in 6 months.

Three serious tools for tracking how often ChatGPT, Perplexity, and AI Overviews cite your brand. Here's what each does well, what they miss, and which one to pick.

Refreshing too often resets authority signals; refreshing too rarely lets citations decay. Here's the data-backed cadence by content type — and the exact edits that drive re-citation, not just dateModified spam.

After 18 months of AEO client work, I distilled what works into a 4-step framework: Clarify, Index, Trust, Echo. Here's the full playbook with examples.
