A keyword research tool pulls the real queries your buyers type into Google and groups them into topic clusters. Enter a seed.

About the Tool

What this tool does.

A keyword research tool pulls the real queries people type into Google around your topic, then groups them into topic clusters you can turn into one piece of content each.

Most keyword tools charge $100 per month and give you numbers that look authoritative but are mostly extrapolated guesses. We skipped the fake volume numbers entirely. What you get instead is 40 to 150 real Google queries pulled from People Also Ask, related searches, and Google autocomplete across six modifier variations (what, how, best, vs, near me, for). Then Claude Sonnet 4.6 groups them into 5 to 12 topic clusters, classifies the search intent of each cluster, and flags which clusters are most likely to earn you AI assistant citations in ChatGPT, Claude, Perplexity, Gemini and Grok.

Each cluster is one piece of content you should publish. Topic coverage is how modern SEO works. Google rewards comprehensive articles that answer every variation of a question, not thin pages that only match the exact query. Match your content to the intent (Informational, Commercial, Transactional, Navigational) and the clusters flagged high AI-citation strength get you cited by AI assistants that are increasingly where searches start in 2026.

FAQ

Frequently Asked Questions

Where do the keywords come from in this research tool?

Live Google data via the Serper API. The tool pulls People Also Ask questions, related searches and Google autocomplete suggestions across six modifier variations (what, how, best, vs, near me, for). These are real queries people type into Google right now, not a stale scraped database.

What is a topic cluster in SEO?

A topic cluster is a group of related keywords that all map to the same piece of content. For example, "best running shoes", "top rated running shoes 2026" and "running shoes under 100 dollars" are one cluster that one well-structured article can rank for. Google rewards comprehensive coverage of a topic over keyword-stuffing individual pages.

What is search intent and why does it matter for SEO?

Search intent is what the user actually wants when they type a query. Informational (they want to learn), Commercial (they are comparing before buying), Transactional (they are ready to buy) or Navigational (they want a specific brand). Mismatched intent is the single biggest reason good content fails to rank.

What do the Informational, Commercial, Transactional and Navigational labels mean?

Informational: write a blog post or guide. Commercial: write a comparison page or buyer's guide. Transactional: write a product or pricing page. Navigational: only relevant for your own brand. Each cluster from this tool gets one intent label so you know exactly what content format to publish.

What do the AI high, medium and low labels mean?

AI citation strength per cluster. High means mostly questions and comparisons that ChatGPT, Claude, Perplexity, Gemini and Grok actively search the web for and cite. Publish these first for AI assistant mentions. Medium is mixed. Low is transactional or navigational queries AI assistants rarely cite.

Why does this keyword research tool not show search volume numbers?

The free data sources for search volume (Keyword Surfer, free Ubersuggest tier) are inaccurate and the paid ones (Ahrefs, SEMrush APIs) cost thousands per month. We skip them rather than show numbers that look authoritative but are wrong. For real volumes, cross-reference with Google Keyword Planner once you have your cluster.

Is this keyword research tool really free?

Yes. Free, no email, no signup. Rate-limited to 5 runs per IP per day because Serper API costs real money per call. No lead gate, no retargeting pixel, no third-party trackers. For site-wide keyword and content strategy, that is what the Middle Mann AI SEO service covers.

Glossary

Keyword research terms used by the tool.

Topic cluster
A group of related keywords that all map to the same piece of content. Google rewards comprehensive coverage of a topic over keyword-stuffing individual pages. Each cluster is one pillar or spoke article you should publish, structured around a single intent.
Search intent
What the user actually wants when they type a query. Informational (they want to learn), Commercial (they are comparing before buying), Transactional (they are ready to buy) or Navigational (they want a specific brand). Mismatched intent is the single biggest reason good content fails to rank.
People Also Ask (PAA)
A Google SERP feature that shows user questions related to the current query, each expanding to a snippet. PAA questions are gold for keyword research because they come from real search behavior and are structured exactly how AI assistants extract Q&A content.
AI citation strength
A per-cluster signal (high, medium, low) that estimates how likely AI assistants like ChatGPT, Claude, Perplexity, Gemini and Grok are to cite content targeting that cluster. High clusters are mostly questions and comparisons that AI assistants actively search the web for.
