Why WordPress sites need AEO and AI visibility

Traditional SEO still matters, but buyers increasingly ask ChatGPT, Perplexity, Claude, Gemini, and Google AI Overviews for recommendations. If those systems never cite your domain, you lose high-intent traffic—even when your Google rankings look fine.

Answer Engine Optimization (AEO) focuses on how AI assistants find, understand, and recommend brands. A WordPress AEO plugin lets SEO, content, and growth teams run that workflow where they already publish: audit crawl files and structured data, ship llms.txt, generate AI-ready meta and drafts, and track citation visibility over time.

SellOnLLM brings those checks into one WordPress admin workflow—without locking features behind a SellOnLLM SaaS plan. You bring OpenAI and Perplexity keys; requests go from your server to those providers directly.

Everything you need for WordPress AI search readiness

One plugin for audit, optimize, monitor, and measure—built for WordPress publishers, ecommerce stores, SaaS sites, and agencies running client AEO audits.

AEO / SEO audit

Site-wide or single-page audits with Overview, Technical, and Content scores. Checks HTTPS, robots.txt for AI crawlers (GPTBot, ClaudeBot, PerplexityBot), XML sitemaps, llms.txt, Open Graph, Twitter Cards, JSON-LD, meta titles/descriptions, FAQ signals, and more.

One-click quick fixes

Publish llms.txt, allow major AI crawlers in robots.txt, confirm your sitemap, and output basic Open Graph / Twitter / JSON-LD when missing—without calling an AI API for those fixes.

llms.txt for WordPress

Generate, edit, regenerate, and serve /llms.txt from your pages and posts so AI systems get a clear map of what matters on your site.

AI readability

Compare what an AI crawler (GPTBot-style, no-JS HTML) can see versus your published content—spot content hidden behind JavaScript that ChatGPT-class systems may miss.

Create Content (OpenAI)

Generate AEO-friendly and SEO-friendly meta titles, descriptions, and body drafts with your OpenAI key. Apply to posts and pages; Yoast SEO and Rank Math meta description fields are detected automatically.

AI visibility monitoring

Track whether Perplexity cites your domain for buyer-intent prompts. Auto-suggest prompts and competitors from site content. Review visibility score, share of voice, history, and CSV export.

AI referral traffic analytics

Optionally measure first-party sessions from ChatGPT, Perplexity, Claude, Gemini, and other AI platforms. Off by default; data stays in your WordPress database—nothing is sent to SellOnLLM.com.

Encrypted BYOK keys

OpenAI and Perplexity keys are stored encrypted in your WordPress database. You control billing with each provider; there is no SellOnLLM metering inside the plugin.

  • SEO and AEO specialists optimizing WordPress sites for ChatGPT, Perplexity, and AI Overviews
  • Content and growth teams tracking AI brand mentions and citation share of voice

Frequently asked questions

What is a WordPress AEO plugin?
An AEO (Answer Engine Optimization) WordPress plugin helps your site get found, understood, and cited by AI answer engines such as ChatGPT, Perplexity, Claude, Gemini, and Google AI Overviews. SellOnLLM includes an AEO/SEO audit, llms.txt tools, AI readability checks, citation monitoring, and optional AI referral analytics.
Is the SellOnLLM WordPress plugin free?
Yes. It is free on WordPress.org with bring-your-own-keys (BYOK). You use your own OpenAI and Perplexity keys. There is no SellOnLLM subscription inside the plugin.
Does this plugin send data to SellOnLLM.com?
No. AI requests go from your WordPress site to OpenAI and/or Perplexity. SellOnLLM.com is linked for product information and support only.
Can I track ChatGPT traffic to my WordPress site?
Yes. AI Traffic is off by default. When enabled in Settings, it may record first-party sessions referred from ChatGPT and other AI platforms. Data stays in your WordPress database. Only enable it if your privacy policy and cookie consent cover this tracking.
What is AI visibility tracking?
AI visibility tracking checks whether AI assistants cite your domain for the prompts you care about. SellOnLLM uses Perplexity to run those checks and stores scores and history in WordPress.
Does SellOnLLM support llms.txt?
Yes. The AEO audit checks for llms.txt, and Quick Fixes can generate, edit, and publish llms.txt from your pages and posts (served at /llms.txt).
Which SEO plugins work with Create Content?
Yoast SEO and Rank Math meta description fields are detected automatically. The post excerpt is always updated as a fallback.
How much do AI Visibility checks cost?
Each prompt is one Perplexity API call (typically sonar). Cost depends on your Perplexity plan—not SellOnLLM.
How is this different from the Chrome extension?
The Chrome extension audits any page you browse and offers hosted Create Content and AI Visibility plans. The WordPress plugin runs in your admin with BYOK, site-wide audits, llms.txt publishing, and first-party AI traffic analytics stored in your database.
