OpenSEO Keyword Clustering

Goal

Group keywords into page-level clusters and decide which existing or new page should target each cluster. This is a keyword mapping workflow, not just a semantic grouping exercise.

Required inputs

• projectId
• A keyword list, saved keyword tag, seed topic, or target domain
• Optional existing URLs/pages to map against

If keywords are not provided, use list_saved_keywords for saved sets, research_keywords for seed discovery, or get_ranked_keywords when the user starts from a target domain.

Project context

The project-context tools are free and shared with the app and other agents.

1. Call get_project_context first and ground the mapping in it — the saved key pages are the existing pages clusters should map to, and the business and goal decide which clusters are worth targeting.
2. This skill needs key pages. If none are saved, run a minimal inline setup: ask the user for the pages that matter, or propose a shortlist from the site, an audit, or Search Console and confirm it, write it back with update_project_context (addKeyPages), then continue the clustering. Never front-load the full interview; suggest seo-project-setup at the end for the rest.
3. Before spending credits, check the research log. If the same research ran within the last 30 days, reuse that result and say so instead of re-buying it.
4. On finish, write back what is durable with update_project_context — new or corrected addKeyPages entries with the topic each page now targets — and append a research log entry: { appendResearchLog: { summary: "Keyword clustering: <keyword set>. Verdict: <conclusion>" } }.

Deliver as a report

Deliver through the seo-report skill, saving with skill: "keyword-clustering". If that skill is not available, say so and stop before writing HTML.

OpenSEO MCP tools

• list_saved_keywords: fetch an existing keyword set, optionally filtered by tags.
• research_keywords: expand a seed when the user starts from a topic.
• get_ranked_keywords: gather exact ranking keywords and URLs when the user starts from a domain or page.
• get_search_console_performance: when Search Console is connected, pull real queries with dimensions: ["query","page"] to map terms to the pages already earning impressions and to surface cannibalization (one query splitting clicks across multiple URLs).
• get_serp_results: validate whether keywords belong on the same page by checking SERP overlap and intent.
• get_local_serp_results: use for local SEO clusters when Maps/local-pack intent should affect page mapping.
• save_keywords: optionally tag final clusters after user confirmation.

Workflow

1. Gather the candidate keyword set.
   • Use get_search_console_performance (dimensions ["query","page"]) when Search Console is connected to start from real queries and the pages already ranking for them.
   • Use get_ranked_keywords for domain/page-driven clustering.
   • Use search_local_businesses and get_local_serp_results when proximity, local packs, or Google Business results determine whether terms belong on location pages.
2. Remove duplicates, irrelevant terms, and terms that clearly require a different product or audience.
3. Build clusters around intent and page type:
   • Same SERP intent and similar ranking pages belong together.
   • Different intent, buyer stage, or SERP format should be split.
   • Similar words do not guarantee the same cluster.
4. For important borderline terms, use a small get_serp_results batch to check overlap.
5. Assign each cluster to:
   • Existing URL, if supplied and appropriate
   • New page recommendation, if no existing page fits
   • Do-not-target / later bucket, if weak or off-strategy
6. Identify cannibalization risk when multiple pages would target the same intent. When Search Console is connected, confirm it from real data with get_search_console_performance (dimensions: ["query","page"]) — the same query sending impressions to multiple URLs.
7. Ask before applying cluster tags with save_keywords.

Output format

h1: the site or keyword set.

If a report template applies (see seo-report), its sections and tone replace this list.

Sections in this order:

1. The map — one or two opening sentences: how many clusters, how many pages to create, how many to update, and any cannibalization found.
2. Clusters — a table of cluster, primary keyword, intent, target page, and priority. Keep secondary keywords in the per-cluster briefs, not in this table.
3. Page briefs — one finding per cluster: the page type and the searcher's problem, then the page to create or update. List required sections and internal links underneath.
4. Cannibalization — a table of the query, the competing URLs, and which one to keep, only when there is real evidence for it.
5. What to do next — an ordered list, including the tag suggestions and the explicit ask before applying them.
6. How this report was made — opens with the skill link line from seo-report, pointing at https://openseo.so/docs/skills/keyword-clustering ("OpenSEO Keyword Clustering skill"), then where the keywords came from, and a note labelling target pages as proposed when no URL data was supplied.

Guardrails

• Do not over-cluster tiny keyword sets. If there are fewer than 10 usable terms, produce a simple map.
• Do not rely on lexical similarity alone. SERP intent wins.
• Do not replace tags broadly without explicit confirmation.
• If existing URL data is missing, label target pages as proposed.
