Full SEO engine + AI visibility (llms.txt, MCP, crawler tracking), all in one free plugin. A-rated on MakeWPFast. Here is how it compares to Yoast, Rank Math, and AIOSEO.
Most free WordPress SEO plugins do one thing: optimize for Google. Shop2LLM does both — traditional SEO and AI visibility (ChatGPT, Claude, Perplexity). Here is why that matters in 2026 when search traffic comes from two directions.
| Feature | Yoast Free | Rank Math Free | Shop2LLM Free |
|---|---|---|---|
| Meta Tags + OG + Twitter Cards | ✅ | ✅ | ✅ |
| XML Sitemap | ✅ | ✅ | ✅ |
| Schema Markup Types | ~5 | ~16 | 19 |
| Multi-Keyword Analysis | ❌ | ✅ | ✅ (unlimited) |
| AI Keyword Suggestions | ❌ | Limited | ✅ (cloud+local) |
| AI Schema Detection | ❌ | ❌ | ✅ |
| Redirect Manager + 404 Log | ❌ (Premium) | ✅ | ✅ |
| GSC Integration | ❌ (Premium) | ✅ | ✅ |
| SEO Audit + Email Reports | ❌ | ✅ | ✅ |
| WooCommerce GTIN/MPN/Brand | ❌ | ✅ | ✅ |
This is where Shop2LLM stands alone among free SEO plugins: llms.txt auto-generation (the emerging standard for AI model content discovery), MCP server endpoint for direct ChatGPT connection, 12 AI crawler tracking (GPTBot, ClaudeBot, PerplexityBot, and 9 more), AI referral analytics (see which AI platforms send actual visitors), and robots.txt AI crawler rules. No other free SEO plugin in the WordPress repository includes any of these.
MakeWPFast independent benchmark (June 2026): +5ms TTFB, negligible memory overhead (under 1 MB), zero additional database queries. "Negligible impact. Safe to install on any hosting." For comparison, WooCommerce scores a D on the same benchmark. Single-file architecture — no includes bloat, no composer dependencies, no npm build. Note: Shop2LLM is developed by the same team that maintains this blog — this is a vendor-published benchmark, not an independent third-party test.
