What is citelayer®?

Your WordPress site, readable by every AI

Search engines rank pages. AI systems cite sources. These are two different games — and most websites are only playing one of them.

citelayer® is a WordPress plugin that makes your content readable and trustworthy for large language models. It injects structured Schema.org data and on top of that enriches your website with several additional data layers needed for AI agents and LLMs to actually get your content right and be able to interact with your site properly. No developer required. Just install, configure, and be ready to show up where your audience is actually asking questions.

Everything you need to be found by AI

Six tightly integrated layers that work together to maximize your content’s visibility across every major AI system — from setup to scoring.

Schema Injection

citelayer® automatically generates and injects Schema.org structured data into your WordPress pages and posts — no manual coding, no plugin conflicts. Your content becomes consistently interpretable by LLMs, search engines, and knowledge graphs alike.

The Method

LLM Visibility Engineering

Traditional SEO optimizes for crawlers. LLM Visibility Engineering optimizes for language models — and the rules are meaningfully different. LLMs don’t rank pages by backlinks. They surface content that is structurally clear, semantically consistent, and verifiably authoritative.

Discovery: Be findable by AI crawlers

llms.txt tells AI systems what your site contains and how to read it. It’s the robots.txt of the LLM era — and it works right now.

Structure: Give AI the context it needs

Structured data injection signals what your content is about. Monitoring reveals whether it’s working. Scoring gives you a continuous feedback loop.

Interaction: Enable real-time AI access

UCP and WebMCP expose your content via the protocols AI agents use to fetch, read and reason over websites on demand.

Social Proof

Trusted by developers, SEOs, and agencies

I’ve been doing SEO for eight years and never thought about AI citations as a separate concern. citelayer® made me realize how much visibility we were leaving on the table. The Schema injection alone changed how our content shows up in Perplexity answers.
Marcus T.
SEO Consultant, Berlin
We manage WordPress sites for about 40 clients. citelayer® is the first plugin I’ve added to our standard stack in two years. Setup is clean, the monitoring dashboard is straightforward, and it actually gives us something new to report on in client calls.
Priya R.
Agency Lead, London
I was skeptical — structured data plugins tend to be bloated. citelayer® is lean, does what it says, and the AI Visibility Score is a genuinely useful metric. I’ve recommended it to everyone in our WordPress developer community.

FAQ

Frequently asked questions

AI visibility refers to how often and how accurately large language models like ChatGPT, Gemini, or Claude reference your website when answering user questions. As more people turn to AI assistants instead of search engines, being cited by these systems is becoming as important as ranking on Google. If your site isn’t structured in a way LLMs can interpret, you’re invisible to a growing share of your potential audience.
citelayer® doesn’t directly control what LLMs say — no tool can. What it does is optimize the signals that influence citation: structured Schema.org data makes your content unambiguous and machine-readable; consistent entity markup establishes topical authority; and monitoring helps you understand what’s working so you can improve continuously. Think of it as technical groundwork that makes citation more likely.
No. citelayer® is built with performance as a constraint, not an afterthought. Schema injection is handled at render time with minimal overhead, and all monitoring runs server-side via scheduled background tasks. Your page load times are not affected.
Yes. citelayer® is designed to coexist with Yoast SEO, Rank Math, All in One SEO, and other common plugins. It adds AI-specific structured data without overwriting your existing schema setup. If there’s a conflict in a specific configuration, our support team will help you resolve it.

Nein – aktuell noch nicht.
Das AI Visibility Dashboard ist ein geplantes Feature für ein zukünftiges Release.

Was das Plugin jetzt schon tut: Es legt die technische Grundlage dafür, dass AI-Systeme Ihre Inhalte überhaupt finden und verstehen können. Durch Schema.org Markup, llms.txt und Markdown-Export stellen Sie sicher, dass ChatGPT, Claude & Co. Ihre Inhalte korrekt interpretieren – eine Voraussetzung für jede spätere Sichtbarkeit.

Denken Sie daran: Ohne saubere Datenstruktur kann keine Messung funktionieren. Wir bauen das Fundament, bevor wir das Dach draufsetzen.

Yes. citelayer® is designed for non-technical WordPress users as well as developers. The setup wizard walks you through configuration step by step, sensible defaults are applied automatically, and you don’t need to write any code. If you run into questions, the documentation covers common setups in plain language.
