OpenSEO is an open-source SEO platform positioned as an alternative to large subscription suites. Its modules cover keyword ideas and live search results, saved keyword lists, position tracking, domain overviews with traffic estimates, backlinks and referring domains, and page-level site audits. A newer AI Visibility area researches prompts and tracks how often a brand is mentioned or cited by AI models, with a Prompt Explorer for comparing answers. The underlying search data comes from DataForSEO. What sets the workflow apart is the MCP server: Claude, Codex and other compatible clients can call the tools directly, save findings as readable reports and remember project context between sessions. Google Search Console can be connected so the agent sees real site performance. The code is public on GitHub for self-hosting, and the hosted version uses a base plan with included usage plus top-ups. ## Key features - **Keyword Research**: Returns keyword ideas with volume, difficulty and intent, alongside the live results page for each term. - **Rank Tracking**: Records the positions of chosen keywords over time at a frequency you set. - **Backlink and Domain Analysis**: Shows a domain's links, referring domains, estimated organic traffic and ranking keywords. - **Site Audit**: Crawls pages and reports technical and on-page problems. - **AI Visibility**: Tracks brand mentions and citations in AI answers and compares one prompt across supported models. - **MCP Server and Skills**: Exposes the tools to AI clients through MCP, with ready-made skills for audits, keyword work and competitor analysis. ## Use cases - **Agent-Led Keyword Clustering**: Ask an AI agent to find and group keywords for a site and store them in the workspace. - **Competitor Research**: See which terms a rival domain ranks for and where its links come from. - **Content Planning**: Build a list of topics worth writing about from saved keyword opportunities. - **Technical Checks**: Audit a site before or after a redesign to catch crawl problems. - **Monitoring AI Search**: Follow whether AI assistants mention your brand for important prompts. ## Things to know - **A subscription is required for hosted use**: Top-up credits do not expire, but the pricing FAQ says an active subscription is needed to use the hosted service. - **Most research consumes credits**: Keyword, backlink, competitor, audit, rank and AI visibility requests use credits; existing projects and fetched data do not. - **Search Console data is not charged**: The pricing page says Google Search Console data does not count against included usage. ## FAQs ### What is OpenSEO?
