The GEO/AEO optimization checklist

Generative Engine Optimization (GEO) and Answer Engine Optimization (AEO) are about one thing: being the source an AI system reaches for when it answers a question. That means ChatGPT, Perplexity, Google's AI Overviews, and the like quoting your page, citing your URL, or repeating your facts. The mechanics overlap heavily with traditional SEO, but the bar is different, you're writing to be quoted, not just ranked.

This is a working checklist. Each item is something you can actually do, with a short note on why it matters. Start at the top; the early items move the needle most.

Write clearly and make answers quotable

LLMs lift text that already reads like a clean answer. If a model has to rewrite your prose to make it usable, it's more likely to reach for a competitor who said it plainly.

• Lead with the answer, then explain. Put the direct answer in the first sentence or two under a heading, then add detail. This is the single highest-leverage writing change you can make.
• Write self-contained sentences. A sentence that makes sense out of context is a sentence that can be quoted out of context. Avoid "as mentioned above" and pronouns that depend on three paragraphs of setup.
• State facts as facts. "Sanaf AI Solutions is based in Oklahoma City" is quotable. "We're proud to call OKC home" is not.
• Keep paragraphs short. Two to four sentences. Dense walls of text are harder for both people and models to extract a clean claim from.
• Use plain language over jargon. Models match user questions to plain phrasing more reliably than to industry shorthand.

Add structured data (schema.org / JSON-LD)

Structured data tells machines what your content is rather than making them infer it. It won't manufacture relevance, but it removes ambiguity, and it's a known input for Google's answer features.

• Use JSON-LD in a <script> tag. It's the format Google recommends and the easiest to maintain because it lives separately from your markup.
• Pick the right types. Organization and WebSite site-wide; Article or BlogPosting for posts; FAQPage for genuine Q&A sections; Product, Service, BreadcrumbList, and LocalBusiness where they apply.
• Only mark up what's visible on the page. Schema that describes content a user can't see violates Google's guidelines and can get you penalized.
• Validate it. Run pages through Google's Rich Results Test and the Schema Markup Validator before shipping. Broken JSON-LD is often silently ignored.
• Be honest in LocalBusiness and Review markup. Don't fabricate ratings or review counts. If you don't have real reviews, leave the field out.

Publish an llms.txt and keep it current

llms.txt is an emerging convention, a plain-Markdown file at your site root that points AI systems to your most important pages. Adoption across AI vendors is still uneven, so treat it as low-cost insurance rather than a guaranteed channel.

• Place it at /llms.txt. Keep the format simple: a short site description followed by curated links with one-line summaries.
• Link your canonical, durable pages. Core service pages, key explainers, contact and about. Skip ephemeral or thin pages.
• Mirror, don't replace, your real site. Every URL in llms.txt should resolve to a live, crawlable page. The file is a map, not a substitute.
• Regenerate it when your site changes. A stale map pointing at dead URLs is worse than none.

Lock down entity and NAP consistency

AI systems build a model of who you are by reconciling mentions across the web. Conflicting information makes you a less confident citation, and for local queries, it can push you out of the answer entirely.

• Keep Name, Address, and Phone (NAP) identical everywhere. Your site, Google Business Profile, directories, and social profiles should match character-for-character.
• Use one canonical name. If you're "Sanaf AI Solutions," don't appear elsewhere as "Sanaf AI Solutions" or "Sanaf AI Solutions, LLC" without a reason. Pick one primary form.
• Reinforce the entity with sameAs. In your Organization schema, list your verified profiles (LinkedIn, GitHub, social) so systems can connect the dots.
• Claim and complete your Google Business Profile if you serve a local market. It's a primary source for local answer engines.

Cite sources and earn citations

Answer engines favor content that looks well-sourced, and they pass citations through to users. Being citable and being a citer reinforce each other.

• Link to primary sources for any external claim, documentation, standards, original research. It signals rigor and gives models a verifiable trail.
• Don't invent statistics. Made-up numbers are a liability; they get fact-checked, and they erode the trust that makes you quotable in the first place. If you don't have a real figure, describe the effect qualitatively.
• Show your expertise. Bylines, author bios, dates, and a clear "who wrote this and why they'd know" go to the E-E-A-T signals that both search and answer engines weigh.
• Earn mentions off-site. Citations in AI answers correlate with how often credible third parties reference you. Real coverage and useful content beat any on-page trick.

Structure pages so machines can parse them

Good structure helps a model find the chunk that answers a question and lift it cleanly.

• Use one <h1> and a logical heading hierarchy. Headings phrased as questions or clear topics give models obvious entry points.
• Add a real FAQ section for questions people actually ask, and answer each in the first sentence. Pair it with FAQPage schema when the Q&A is visible on the page.
• Use lists and tables for enumerable facts. Steps, comparisons, and specs are easier to extract from structured formats than from prose.
• Front-load the page. Put the core answer above the fold; don't bury it under a long preamble.

Don't skip the technical SEO basics

None of the above matters if a crawler can't reach or render your page. These are table stakes.

• Make sure you're crawlable. Check robots.txt, confirm important pages aren't noindex, and don't block the AI crawlers you want (e.g., GPTBot, PerplexityBot) unless you mean to.
• Render content server-side where you can. Content that only appears after heavy client-side JavaScript is less reliably indexed.
• Keep it fast and stable. Good Core Web Vitals and reasonable load times help crawl budget and user experience alike.
• Maintain clean URLs, canonicals, and a sitemap. Help engines find the right version of each page and avoid duplicate-content confusion.
• Serve HTTPS and fix broken links. Basic trust and crawl-health signals.

Keep content fresh

Answer engines lean toward recent, maintained content, especially for anything time-sensitive.

• Show real dates. Use accurate datePublished and dateModified, and only bump the modified date when you actually changed something.
• Revisit cornerstone pages on a schedule. Update facts, prune dead links, and add new questions as they surface.
• Retire or redirect stale pages rather than leaving outdated claims live to be quoted back at you.

Takeaway

GEO and AEO reward the same things good engineering does: clarity, accurate structure, honest sourcing, and solid fundamentals. Start with quotable writing and clean structure, layer in schema and llms.txt, and keep the technical basics healthy. There's no trick that substitutes for being genuinely useful and verifiably accurate, that's what gets cited.
