Description

Agentic SEO Check is a free, open-source audit tool from RIVI Software that checks a page or a whole site for search engines and for AI answer engines such as ChatGPT, Claude and Perplexity. Its difference is the output: every finding comes with the exact edit that fixes it, ready for you or your coding agent to apply.

Read our full Agentic SEO Check review

It launched on Product Hunt on 12 November 2026. You can run it in the browser, from the command line, or as an MCP server inside Claude, Cursor, Codex and other MCP clients. Two audits run side by side, each with its own score: 184 SEO rules and 32 AEO rules.

Who Agentic SEO Check Is For

  • SEO specialists who want fast technical audits with concrete fixes rather than a long list of warnings.
  • Developers and coding-agent users who want an agent to audit, fix and re-check a site or build directory by itself.
  • Content and growth marketers checking whether AI answer engines can crawl, quote and attribute their pages.
  • Agencies needing a free first-pass audit for prospects.

Core Capabilities

SEO Audit with Fixes

Rules cover titles, canonicals, structured data, hreflang, headings, images, links, Open Graph, performance and site-wide checks. Each finding carries a rule ID, severity, CSS selector, evidence and the edit that fixes it.

AEO Audit for AI Answer Engines

It reads robots.txt for 25 crawlers, separating search, AI answer and model training bots such as OAI-SearchBot, PerplexityBot and GPTBot, and checks snippet opt-outs, authors, dates and llms.txt.

Built for Coding Agents

A coding agent can audit a live URL, a build folder or raw HTML, apply the fixes and re-audit. Words only you should write are left as placeholders.

Hosted MCP Server and CLI

A hosted MCP server needs no account or key. The npm package runs the same audits locally, adds optional JavaScript rendering and Lighthouse checks, and fits CI pipelines.

Pros & Cons

Pros

  • Completely free and open source, with no account needed for the web audit or hosted MCP server.
  • Fixes are specific enough for a coding agent to apply and verify.
  • Covers AI answer engine readiness, including crawler-by-crawler robots.txt checks, alongside classic SEO.

Cons

  • It audits pages as served; it does not track rankings or AI citations over time.
  • The web audit reads HTML without running JavaScript, so client-rendered sites need the local CLI with rendering.
  • A new tool from a small team, with a young community and limited support channels beyond GitHub.

Where Agentic SEO Check Fits
