Citelayer® FAQ — Frequently Asked Questions About AI Visibility

7 min read


You have questions. Fair enough — AI visibility is a new category, and healthy skepticism beats blind trust. Below you find straight answers to the concerns we hear most often. No spin, no weasel words. If something has caveats, we say so.

Does Citelayer® replace my SEO plugin?

No. Citelayer® complements your SEO plugin — it does not replace it. SEO plugins like Yoast, Rank Math, and AIOSEO optimize your site for search engines (Google, Bing). Citelayer® optimizes your site for AI assistants (ChatGPT, Perplexity, Claude). You need both.

The compatibility system automatically detects your active SEO plugin and works alongside it. In Enhance mode (the default), Citelayer® adds AI-relevant structured data to your existing schema output. In Replace mode, it takes over Schema and llms.txt generation entirely — useful if your SEO plugin’s schema conflicts with what AI models need.

Read more about how both systems coexist in the SEO Compatibility guide.

Will it slow down my site?

No. Citelayer® makes zero external API calls. All data is generated locally on your server — nothing phones home, nothing waits on a third-party service.

Performance details:

  • Schema and llms.txt are cached via WordPress transients for 1 hour.
  • WebMCP context is cached for 7 days.
  • Markdown output is cached for 24 hours.
  • The .md endpoints only generate Markdown when an AI crawler or user requests them — they do not run on regular page loads.
  • No JavaScript is added to the frontend. Zero. Your visitors never download or execute Citelayer code.

Your PageSpeed score stays exactly where it is.

Is AI visibility actually proven to matter?

Yes, with caveats. AI assistants like ChatGPT, Perplexity, and Claude increasingly reference web content in their responses. When they do, structured data (Schema.org) helps these models attribute and cite sources correctly. Discovery files like llms.txt help AI crawlers find and understand your content before they ever generate a response.

The honest caveat: this is an emerging field. There is no “AI ranking algorithm” to game. Nobody can promise you position #1 in a ChatGPT response. But making your content machine-readable is a foundational step — similar to how SEO started with meta tags and sitemaps before anyone fully understood Google’s ranking factors.

What happens if I deactivate the plugin?

Clean removal. No lock-in.

  • No database tables are created, so none need to be removed.
  • Options stored in wp_options are standard WordPress settings.
  • Transient caches expire automatically — WordPress cleans them up on its own.
  • Rewrite rules are flushed on deactivation, so your URL structure stays clean.

Your site returns to its pre-Citelayer state with no leftover code and no orphaned data. If you reactivate later, your settings are still there.

Does it work with page builders (Elementor, Divi, etc.)?

Yes. Citelayer® hooks into WordPress core functions (the_content, wp_head). It reads the final rendered HTML output, not the page builder’s internal shortcodes or proprietary format.

The Markdown converter processes whatever HTML WordPress outputs after all plugins and builders have done their work. It does not matter whether you build pages with Elementor, Divi, Beaver Builder, WPBakery, Breakdance, Bricks, or the native block editor. If WordPress can render it, Citelayer® can convert it.

Do I need the premium addons?

Most sites don’t. The free plugin covers:

  • Schema.org markup (Organization, WebSite, Article)
  • llms.txt generation
  • Markdown endpoints for every post and page
  • WebMCP server context
  • UCP Discovery
  • Full SEO plugin compatibility

The premium addons — Citelayer® for WooCommerce and Citelayer® for Easy Digital Downloads — add specialized Product schema (with price, availability, reviews, and variant data) and enhanced UCP endpoints designed for AI-powered shopping and product discovery. You only need them if you run an online store and want AI assistants to accurately surface your products.

Is llms.txt an official standard?

Not yet — and that’s fine. llms.txt was proposed by Andrej Karpathy (co-founder of OpenAI, former Tesla AI director) as a convention for websites to describe themselves to AI models. It is documented at llmstxt.org.

It is not an RFC or W3C standard. It is a community convention that is gaining rapid adoption. The parallel is robots.txt: that file was a de facto convention for years before it received formal standardization. Adoption came first, specification followed. llms.txt is on a similar trajectory.

How is this different from just adding Schema with Yoast?

Yoast (and Rank Math, AIOSEO, and others) generate Schema optimized for Google’s Rich Results — product stars, FAQ accordions, breadcrumbs, how-to steps. Their goal is earning visual enhancements in search result pages.

Citelayer® generates Schema optimized for AI citation — Organization identity, content attribution, publication metadata, expertise signals. In Enhance mode, Citelayer® adds AI-relevant fields like knowsAbout and topical expertise markers to your existing SEO plugin’s schema output without removing anything your SEO plugin already provides.

Beyond Schema, Citelayer® provides four additional protocols that no SEO plugin covers:

  • llms.txt — site-level AI discovery file
  • Markdown endpoints — clean, parseable content for every page
  • WebMCP — Model Context Protocol server integration
  • UCP — Universal Context Protocol discovery

Will this help me rank in ChatGPT/Perplexity?

Honest answer: there is no guaranteed “ranking” in AI responses the way there is in Google search results. AI models do not have a public ranking algorithm. Nobody — no plugin, no agency, no consultant — can promise you a specific position in an AI-generated answer.

What Citelayer® does: it makes your content findable (llms.txt, UCP), parseable (Markdown, Schema), and citable (structured attribution data). These are necessary conditions for being cited by AI — not sufficient guarantees.

Think of it like SEO fundamentals: you cannot guarantee position #1 on Google, but you can ensure your site is crawlable, well-structured, and technically sound. That is what Citelayer® does for the AI layer.

Can I customize what appears in llms.txt?

Yes. Use the citelayer_llmstxt_content filter to modify, extend, or remove content from your llms.txt output. The filter receives an array of content lines and expects an array in return.

add_filter( 'citelayer_llmstxt_content', function( $content ) {
    $content[] = '';
    $content[] = '## Custom Section';
    $content[] = '- Custom link: https://example.com/special-page';
    return $content;
} );

You can add custom sections, remove auto-generated lines, reorder content, or inject dynamic data from other plugins. The filter runs after Citelayer® assembles the default output, so you always have the full generated content to work with.

See the complete list of available filters in Hooks & Filters.

Does Bot Analytics track real users?

No. Only known AI crawlers. No JavaScript, no impact on human visitor privacy.

For tracking humans arriving from AI platforms, see AI Referral Tracking.

What happens to old bot visit data?

Records older than 90 days are auto-deleted daily. Adjust via citelayer_bot_analytics_cleanup_days filter. Export via CSV before data ages out.

I use a caching plugin — will Bot Analytics still work?

Configure your cache plugin to bypass for AI bot user-agents. See Cache Plugin Compatibility.

What is the AI Readiness Scanner?

Automated audit: Schema.org, robots.txt, llms.txt, Content-Signal Headers, and WooCommerce product checks. Score 0–100 with actionable fixes.

Does citelayer® add JavaScript to my frontend?

Only AI Referral Tracking adds a small script. Core protocols are server-side only. Disable referral tracking = zero frontend JS.

What AI referral sources does Citelayer® detect?

  • ChatGPT
  • Perplexity
  • Claude
  • Gemini
  • Microsoft Copilot
  • You.com
  • Phind
  • Kagi
  • Andi
