AEO readiness benchmark
Most websites still have technical gaps AI can see.
We scan public websites against a deterministic technical rubric. The point is not another visibility score; it is to show exactly where AI systems struggle to discover, read or interact with the site.

Why AEO needs engineering
AEO is not only a content problem.
Good content still matters. But AI systems also depend on crawl access, server responses, JavaScript behavior, structured data accuracy and machine-readable interfaces. Those are engineering issues, not copywriting issues.
Technical access comes first
If an AI crawler cannot reliably fetch the page, stronger copy will not solve the problem.

A page can rank well in Google while still being difficult for an AI system to parse or cite.

Your website now serves humans, search crawlers and AI systems that consume it differently.

Four questions every AI-ready website should answer.
We separate the work into discovery, readability, interaction and representation so you can see whether the problem is visibility, site structure, agent usability or what AI systems are saying about the brand.
15Checks
Discovery
Can AI systems find the site and understand what it offers?
16Checks
Readability
Can they parse, extract and cite the content accurately?
13Checks
Interaction
Can an agent complete useful actions such as search, forms or transactions?
6Checks
Representation
How often are you mentioned, cited and described accurately over time?
How the AEO service works
Audit. Fix. Re-test. Monitor.
We do not stop at a report. Every failed check is tied to evidence, prioritized, remediated where approved, then re-tested against the same rubric so the before-and-after is measurable.
Audit with evidence
URL-level findings and failed checks
Deployable remediation
files, patches or implementation guidance
Re-test and monitor
same scorecard, then ongoing AI representation tracking
Who this is for
Best suited to digital-first companies with something meaningful to optimize.
Code4X is a stronger fit when your website is part of the buying journey, your content estate is substantial, and marketing and engineering both have a stake in AI discovery.
B2B SaaS, software and technology
Product pages, documentation, APIs, help content and demo flows create a large surface for AI discovery and citation.
Marketplaces, ecommerce and transactional sites
Agent interaction matters when users or AI systems need to search, compare, enquire, book, add to cart or transact.
Knowledge-rich and high-value digital businesses
Large content estates, research, training, fintech and specialist platforms benefit when accurate AI representation can influence high-value customer decisions.
How Code4X differs from typical AEO tools
Most AEO tools measure visibility. We fix the website underneath it.
Mentions, citations and share of voice matter. But if the underlying site is difficult for AI to discover, parse or use, monitoring alone does not solve the problem.
| Approach | Primary question | What you get |
|---|---|---|
| Visibility monitoring | Are AI engines mentioning the brand? | Mentions, citations and share-of-voice data |
| Content-led AEO | Is the content structured around answer intent? | Recommendations for copy, entities and topic coverage |
| Technical SEO audit | Can search crawlers index and rank the site? | Search-focused technical findings |
| Code4X technical AEO | Can AI systems find, understand, cite and use the site? | Evidence, readiness score, remediation files and ongoing representation tracking |
AEO services
Start with evidence, then decide how far to go.
You can begin with a technical AEO audit, move into remediation, or retain Code4X for recurring re-audits and AI representation monitoring.

AEO knowledge base
Learn the technical side of Answer Engine Optimization.
Practical guides on AEO, AI crawlers, llms.txt, JavaScript rendering, content negotiation, schema accuracy, WebMCP and the standards shaping AI-readable websites.
Technical guides
Start with the first four guides below — they cover the failures that account for most audits.
llms.txt
What it is, what the file looks like, and the honest state of the evidence.
Tier 1AI crawlers & robots.txt
Block training, allow citations. Template for 13 named agents.
Tier 1JavaScript & AI crawlers
Most AI crawlers never run JavaScript. How to check and fix it.
Tier 1Content negotiation
Serve markdown instead of HTML — cuts reading cost by 80-99%.
Tier 2Schema drift
When structured data contradicts your visible page.
Tier 2Lighthouse agentic browsing
What Google's experimental audit scores and what it skips.
Tier 2WebMCP
Let sites expose callable tools to agents. Adoption is near zero.
CategoryGoogle AI Overviews
What actually influences inclusion, and why there is no schema.
Concepts & comparisons
