Can ChatGPT, Perplexity even see your site?
Free Answer Engine Optimization audit. Paste any URL — we check whether supported crawlers can access the page and inspect content signals. 135+ checks across SEO + AI crawler diagnostics from a public URL. No signup.
Answer engine optimization (AEO) is structuring content so an answer engine can extract and cite it, rather than only ranking it. In practice that means three things: the crawler must be allowed in, the content must exist in the server-rendered HTML, and each page must answer its question in a self-contained passage that still makes sense once it is quoted.
What is Answer Engine Optimization?
Answer Engine Optimization (AEO) is a broad, informal term for work intended to make information accessible and understandable to answer systems. Products use the term differently, and no set of page changes guarantees that a system will cite a source.
AEO work starts with sound SEO basics and readable page structure. There is no special passage length or schema type that guarantees an AI citation. This audit checks supported robots.txt rules and selected page signals; it does not score citation likelihood.

Six areas teams may review, measured differently.
This is an editorial framework, not six scored product modules. The scan reports measured crawler and page diagnostics alongside its separate eight-pillar SEO score.
Crawlability for AI agents
The scan reads robots.txt for supported AI crawlers and checks whether page content is available in fetched HTML. This shows crawl-access and rendering signals; it cannot predict whether an engine will cite a page.
- GPTBot / ClaudeBot / PerplexityBot / Google-Extended access
- robots.txt rules for supported AI user agents
- Fetched HTML availability and semantic element counts
- llms.txt presence and basic format checks
- Selected freshness metadata and FAQ/HowTo markup presence
Readable page structure
LLMs lift sentences and paragraphs, not pages. Your content needs to be quotable in 1-3 sentence chunks with clean attribution paths.
- Content structure signals: headings, lists, tables and definition elements
- Semantic HTML element counts
- Page word count and headings density
- No citation probability based on paragraph length
Structured data signals
The scan records FAQPage and HowTo presence. Structured data can describe content, but no schema type guarantees inclusion in an AI answer or special Google AI feature.
- FAQPage and HowTo presence checks
- Structured data recommendations in the SEO audit
- Author and date metadata signals
- No claim that markup changes AI citation odds
Selected content and freshness signals
The audit records selected page metadata and content structure. It does not measure author trust, entity authority, or likelihood of being cited.
- Named author with bio page + credentials
- Outbound citations to authoritative sources (.gov/.edu/journals)
- Freshness signals (datePublished, dateModified, version stamps)
- Entity disambiguation (sameAs links to Wikipedia/Wikidata)
- Reviews + testimonials with verifiable identity
AI brand mention testing
Agency plans can run prompt-based brand mention checks against supported language models. These are model response tests, not search rankings, source citations, sentiment, or ongoing visibility measurements.
- Prompt-based brand mention tests (Agency+)
- Captured model response and whether the brand appeared
- No per-engine citation or AI Overview monitoring
- No sentiment, competitor comparison, or weekly visibility alerts
Technical foundation
AEO sits on top of classic SEO + Core Web Vitals. If your page is slow, broken or unindexable, no amount of structured content will save you.
- 135+ technical SEO checks across 10 audit areas
- Core Web Vitals (LCP, CLS, INP) from CrUX field data
- Mobile-first rendering + viewport checks
- Security headers + HTTPS + mixed-content scan
- Structured data and rich-result validation checks
One audit: SEO scores plus AI access diagnostics.
- Title · meta · canonical · hreflang
- Core Web Vitals + CrUX field data
- Internal link graph + anchor analysis
- Mobile + accessibility + security headers
- AI crawler access (GPTBot · ClaudeBot · PerplexityBot)
- Page structure checks; no assumed ideal answer length
- Selected schema and metadata diagnostics
- No AI citation or entity trust score
Clear diagnostics and prioritised actions.

AEO, in plain English.
What is Answer Engine Optimization (AEO)?+
Answer Engine Optimization (AEO) describes efforts to make content accessible and understandable to answer systems. Technical checks can confirm some crawler and page properties, but cannot guarantee that a system will select or cite a page.
How is AEO different from traditional SEO?+
AEO is an informal term used for work intended to make information accessible and understandable to answer systems. There is no established ideal passage length or special schema requirement that guarantees a citation. SlapMyWeb checks crawler access and selected page structure signals as part of its audit.
Which AI bots should I allow to crawl my site?+
The right policy depends on your goals. GPTBot, ClaudeBot, and Google-Extended are primarily training or model-use controls; OAI-SearchBot and ChatGPT-User support OpenAI search or user-requested fetches. Google-Extended does not control Google Search inclusion. SlapMyWeb checks supported robots.txt rules; it cannot verify every CDN or firewall policy.
How long does an AEO audit take?+
Scan duration varies by site and queue load. SlapMyWeb runs the agents available on your plan and returns diagnostics and prioritized actions. Pro adds full fix code. AI citation likelihood is not measured.
Is the AEO audit really free?+
The website scan is free with no signup. Paid plans add plan-specific scan limits and agency features. Agency users can run prompt-based brand mention tests; those tests do not measure citations or search visibility over time.
What is the difference between AEO and GEO?+
The terms overlap and are used inconsistently. Both describe efforts to make content accessible and understandable to generative answer systems. SlapMyWeb checks selected technical and content signals; it does not report whether a site is actually cited in AI answers.
