SEO vs AEO vs GEO comparisons
SEO, AEO and GEO overlap. SEO includes making pages accessible, relevant and useful for search; AEO emphasizes answering the question clearly; GEO concerns visibility and accurate representation in generated answers. They are not mutually exclusive replacements. Start with the business question: do you need more qualified visits, fewer misunderstood product answers, or a clearer understanding of citations? Choose measurements that match the task rather than declaring one discipline universally superior.

Files with different purposes are not substitutes
robots.txt communicates crawl preferences to compliant agents; sitemap.xml lists URLs for discovery; llms.txt is a proposed Markdown guide to useful content. None is a password wall, and publishing any of them does not ensure index inclusion or a citation. A website can legitimately need all three. Keep sensitive pages protected by authentication, maintain real canonical URLs, and distinguish file syntax validation from proof that a particular engine consumed a file.
A practical comparison method
List the outcome, required inputs, observable output and limitations before choosing a workflow. For example, a robots audit can identify a restrictive rule, while an answer check can show whether a brand was cited for one question. The first is technical evidence; the second is a response snapshot. After changing a crawl rule, check the live file, server response and representative URLs before investigating content quality. Do not assume that generating schema fixes a blocked page.
Report uncertainty in before-and-after comparisons
Use the same language, market, prompt set and engines, and keep dates and source URLs. Document changes in products or pages during the test. Citation rate, answer accuracy, organic impressions and conversions answer different questions; report them separately. Simulated results are scenarios, not observed rankings. Comparisons should include where each approach fails and the conditions under which a conclusion might change.
| Check | Evidence to retain | Action |
|---|---|---|
| SEO | Index coverage, impressions and qualified visits | Resolve discovery and page-quality issues |
| AEO | Accuracy and completeness of direct answers | Make the question and answer unambiguous |
| GEO | Recorded engine responses and cited URLs | Check retrieval, context and corroboration |
| robots.txt | Published user-agent groups and URL access | Set intentional crawl preferences |
| llms.txt | Markdown guide and working destination links | Provide curated context, not permissions |
Implementation checklist
- Define the decision and success measure first.
- Use comparable dates, questions and audience settings.
- Separate tool output from business outcomes.
- Include limitations as well as benefits.
- Do not turn a correlation into a causal claim.
A repeatable workflow
- 1Establish a baseline
Save the page URL, date, language, target market and exact questions before editing. Record what the page actually says and what each tested answer cites; a mention without a source link is not a citation.
- 2Make one coherent change
Resolve the clearest failure first, then check the published page rather than only an editor preview. Keep an implementation log so unrelated redesigns, campaigns or product changes are not mistaken for the effect of this work.
- 3Repeat and compare
Repeat the same questions and technical checks after deployment. Keep engines and measurement conditions consistent, report sample size, and inspect answer accuracy alongside citations. A single response is not a stable ranking.
Frequently asked questions
Does this guarantee an AI citation?
No. A crawlable, accurate page can still be omitted. Retrieval, source selection and generated answers vary between products and requests; these checks improve the evidence available, not guarantee placement.
How do I tell whether an improvement worked?
Compare like-for-like checks and retain the underlying evidence. Track correct brand mentions, source-linked citations and qualified referral visits separately. Do not call a technical score a traffic forecast or attribute every change to one edit.

Industry-specific GEO starts with a real question, not a generic page containing an industry keyword. A software buyer may need compatibility, security and pricing details; a patient may need eligibility, risks and clinician qualifications. Write the answer in the language and jurisdiction of the audience, state who it applies to, and link the source of any claim. Search accessibility, useful content and trustworthy references remain important even when the final answer appears in an AI interface.
llms.txt is a proposed Markdown convention for presenting a concise site overview and curated links. It is not a robots policy, licensing agreement, authentication control or universal AI indexing requirement. An H1 site name, a useful summary and organized Markdown links help readers understand the site. The proposal does not mandate a section literally called Docs or a universal 150-character summary. Adoption differs by consumer; do not claim that every major AI crawler reads it.
A search assistant can retrieve sources at answer time, use an index or answer from model knowledge without browsing. Its crawler and training controls may be separate. Test the actual feature and question you care about rather than assuming one user-agent rule controls the whole product. The engine guides here help organize that investigation; they are not claims that the vendors publish identical ranking rules.
Local AI visibility depends on accurate business facts and useful answers for the area you actually serve. A city keyword alone is not a reason to publish another page. State genuine service coverage, contact options, hours and location-specific limitations. Do not invent an office, address, local partnership, market-share statistic or citation benchmark to make a template look more substantial.
AI-search terms often describe different layers of a system. Crawling retrieves a page; indexing organizes available information; retrieval selects material for a question; generation produces an answer. A citation is an attribution in that answer, not proof of all preceding steps. Definitions are useful when they help you locate a problem, choose an appropriate check and avoid claiming more than the evidence shows.
