citehq

People are asking AI instead of Googling. Is your site showing up in those answers?
CiteHQ adds an llms.txt file to your WordPress site—the emerging standard that helps AI tools understand and cite your content.
One click. No setup. Works immediately.
<h4>Why AI Can’t Find Your Content</h4>
When someone asks ChatGPT or Claude a question your content could answer, AI has to guess what your site is about. Most sites get overlooked.
<h4>What is llms.txt?</h4>
CiteHQ creates an llms.txt file at yoursite.com/llms.txt that tells AI:
<ul>
<li>What your site is about</li>
<li>Which pages matter most</li>
<li>How to describe your content</li>
</ul>
It’s like robots.txt, but for AI instead of search engines.
<h4>AI Search Statistics</h4>
<ul>
<li>400M+ weekly ChatGPT users</li>
<li>AI search traffic up 527% year-over-year</li>
<li>844,000+ sites already have llms.txt</li>
<li>Used by Anthropic, Stripe, Cloudflare, and others</li>
</ul>
Early adopters have the advantage. Setup takes 60 seconds.
<h4>llms.txt Features</h4>
<ul>
<li>Instant Setup — Activate and done. Your llms.txt is live.</li>
<li>Smart Defaults — Automatically includes your published content.</li>
<li>Full Control — Choose which posts, pages, and media to include.</li>
<li>Media Library Support — Include images with alt text, captions, and descriptions.</li>
<li>URL Pattern Exclusion — Exclude URLs using wildcards (e.g., /private/*, *.pdf).</li>
<li>SEO Friendly — Respects noindex settings from Yoast, Rank Math, and others.</li>
<li>Auto Updates — Regenerates when you publish new content.</li>
<li>Full Content Export — Also generates llms-full.txt with complete post content.</li>
</ul>
<h4>Plugin Compatibility</h4>
<ul>
<li>Yoast SEO, Rank Math, All In One SEO, SEOPress</li>
<li>Elementor, Divi, Beaver Builder</li>
<li>WooCommerce</li>
<li>WP Rocket, LiteSpeed, W3 Total Cache</li>
</ul>
