Siteimprove
Updated 2026-05-26Web-governance platform founded 2003 in Copenhagen, retrofitting accessibility, SEO, and content compliance with AI-search visibility. Majority-owned by Nordic Capital. Recent moves: Advanced AEO Insights at Adobe Summit, the Siteimprove.ai agentic platform on Amazon Bedrock, and an Optimizely agent-to-agent integration.
Three scores, refreshed weekly from live market signals rather than a once-a-year analyst report. Presence is how established a vendor is in the market right now. Velocity is how fast they are shipping, raising, and winning customers. Agent Readiness is how easily your own agents can build on them through an API, MCP server, SDK, or CLI. Scores are relative across the vendors we track; the raw inputs ship in the downloadable dataset.
The Solution & Approach
Siteimprove is a web-governance platform: accessibility, SEO quality, content compliance, and analytics for enterprise web teams. Founded in 2003, it is the kind of incumbent the AEO wave is retrofitting rather than displacing.
The retrofit ran through three moves. First the MarketMuse content-intelligence acquisition in October 2024. Then a March 2025 CEO change to Nayaki Nayyar, formerly of Securonix. Then the August 2025 launch of Siteimprove.ai, an agentic content-intelligence platform built on Amazon Bedrock and Nova, whose Search agents target search engines, LLMs, and AI discovery platforms. AEO surfaced as a named product, Advanced AEO Insights, on April 20, 2026 at Adobe Summit, tracking AI citations, share of answers, and brand sentiment across answer engines.
Siteimprove is classified AI-Transitioned. The core accessibility, governance, and SEO business predates LLMs and would survive without them, but the 2025 to 2026 product direction is built around generative AI. That separates it from AEO-native entrants like Profound, where the entire product assumes answer engines exist.
Best for
Enterprise web teams already invested in accessibility, SEO quality, and content governance that want AI-search visibility added on top of an existing platform rather than bought from a standalone AEO tool.

Agent Experience
How you build on this platform (or wire it into your own agents):
| Surface | Available | Docs |
|---|---|---|
| API | Yes (REST) | developer.siteimprove.com |
| MCP | No | — |
| SDK | Partial (CMS plugin SDK) | developer.siteimprove.com |
| CLI | No | — |
| llms.txt | No | — |
Siteimprove ships a documented public REST API (with an OpenAPI spec) and a CMS-plugin SDK, plus agent-to-agent interop inside Optimizely and an agentic platform on Amazon Bedrock and Nova. No MCP or CLI yet, but there is a real surface to build on.
