# Technical & Semantic Foundations

## Summary

CiteSurge finds the crawl, rendering, canonical, structured-data, sitemap, performance, and AI-readable-file problems that make public pages harder to reach or interpret. Web and engineering teams receive specific fixes tied to the affected route.

## What blocks access and interpretation?

A page can look correct in a browser while crawler rules, edge controls, client-only rendering, duplicate canonicals, stale sitemaps, or mismatched schema make it harder to inspect. CiteSurge checks the public route and the signals that describe it, then separates technical readiness from any claim that an AI system will use the page.

## Which technical signals does CiteSurge review?

The review connects each technical barrier to a public route, responsible owner, and verifiable change. It does not treat one passing check as proof that every layer works.

- Crawler policy and live-delivery checks across origin and edge behavior.
- Rendered-content, canonical, metadata, sitemap, and structured-data consistency findings.
- AI-readable-file and public-route checks that exclude private or future content.
- Specific technical changes for web and engineering owners, with a verification step for each fix.

## What does your team receive?

Your team receives a route-level plan for removing known barriers to access, consistency, and interpretation. Completed fixes can be verified directly. Later AI visibility measurement remains a separate question.

- Crawler and CDN policy reviewed together for the affected public routes.
- Canonical, sitemap, metadata, and rendered-content consistency checks.
- Structured data limited to facts visible and supported on the page.
- AI-readable files that map live canonical content without private or future routes.

## What supports each technical finding?

CiteSurge checks the origin response, robots policy, rendered page, canonical URL, sitemap entry, metadata, structured data, security policy, performance result, and AI-readable file together. Each finding names the observed state, affected route, and limitation.

- OpenAI says OAI-SearchBot must be able to access public content for summaries and snippets in ChatGPT search, while GPTBot controls potential training rather than search retrieval. (OpenAI · Publishers and Developers FAQ: https://help.openai.com/en/articles/12627856-publishers-and-developers-faq)
- Anthropic documents three separate agents: Claude-SearchBot for search quality, Claude-User for user-directed retrieval, and ClaudeBot for content that could contribute to training.

- Google says pages must meet Search technical requirements, be indexed, and be snippet-eligible to be eligible for its generative Search features. It also says no special AI file or schema is required, and eligibility does not guarantee crawl, indexing, or serving.

## Frequently asked questions

### What are technical and semantic foundations?

They are the crawl, rendering, canonical, structured-data, metadata, sitemap, performance, and content signals that keep public pages accessible, consistent, and understandable.

### What is llms.txt?

llms.txt is a voluntary map of useful public content. Google Search ignores it. CiteSurge can review it as an optional diagnostic when named non-Google surfaces such as ChatGPT or Claude are in scope, but the file does not show that either service used it.

### Which crawlers should a site allow?

That is a policy decision based on search access, user-requested retrieval, training preferences, and legal requirements. Origin robots rules, CDN controls, and verified-bot policy should agree; a spoofed user-agent test is not proof of crawler identity.

### Do Core Web Vitals affect AI citations?

Core Web Vitals measure user experience and remain useful web-quality signals. CiteSurge reports them separately from later AI visibility observations.

### What structured data does CiteSurge recommend?

Only types supported by the visible page and underlying facts. Unsupported decorative markup should be removed.

### Does the site need to be rebuilt?

The audit determines the scope. Some issues are configuration changes; others require template or content work. Each recommendation identifies the affected surface and implementation path.

## Next step

The audit shows which public routes have supported crawl, rendering, canonical, schema, sitemap, performance, or AI-readable-file problems. CiteSurge can turn those findings into specific changes for the responsible web and engineering owners. Request a free GEO audit: https://citesurge.com/contact?intent=audit
