Toutmark is an AI citation platform aligned with Google’s May 2026 AI Optimization guidance. This plugin connects your WordPress site to your Toutmark account and adds the technical signals that AI engines reward — all visible to every visitor, with no user-agent-conditional content delivery and no hidden text.
What it does
- Schema injection. Emits standard schema.org JSON-LD on each page via the
wp_headhook, sourced from your Toutmark account. Visible to humans and bots alike. - /llms.txt + /llms-full.txt files. Serves public files at the root of your site (used by ChatGPT and Perplexity): llms.txt is the index, llms-full.txt carries the full text of your published content so AI systems can read everything in one fetch. Both populated from your Toutmark account, both visible to any visitor.
- AI bot reachability. Runs a daily ping back to Toutmark; the Toutmark service then verifies that GPTBot, ClaudeBot, PerplexityBot, ChatGPT-User, and Googlebot can reach your site and surfaces results in your dashboard.
- One-click connect. A “Connect to Toutmark” button on the plugin’s settings page generates a WordPress Application Password using core’s
WP_Application_PasswordsAPI and sends it to Toutmark over HTTPS, so Toutmark agents can publish drafts to your approval queue via the standard REST API. You can revoke the password any time from Users Profile Application Passwords.
What it does NOT do
- Does not deliver different content to bots than to humans. Google’s spam policy treats user-agent-conditional content delivery as a manual-action risk. Toutmark refuses to do it on principle.
- Does not inject hidden text, white-on-white text, off-screen text, zero-size text, or
display:nonecontent blocks. Every character is visible to humans at full opacity, in normal document flow. - Does not modify your post content. Schema and llms.txt content are added via standard WordPress hooks (
wp_head, rewrite rules); your existing posts and pages are untouched. - Does not publish anything without your approval. Toutmark agents publish drafts to your WordPress site; you approve in your Toutmark dashboard before anything goes live.
- Does not work without an active Toutmark subscription — the plugin no-ops if unreachable or inactive.
Compliance with Google’s May 2026 spam policy
Google’s updated spam policy targets user-agent-conditional content (cloaking), hidden or invisible text, “AI-only” content blocks visible only to LLM bots, and inauthentic mentions. Toutmark does none of these. Every signal we add is plainly visible to anyone who visits your site.
Requirements

- WordPress 6.0+, PHP 7.4+.
