How to do keyword research (4 steps)
Keyword research starts not from words you happen to think of, but from words people actually search. The following four steps build the foundation for content that answers real search intent.
- 1
Bulk-collect suggest keywords to surface candidates
Enter a seed keyword and bulk-collect Google Suggest (autocomplete) candidates. Because these reflect what users actually search for, you gather keywords with real demand efficiently.
- 2
Classify keywords by search intent
Sort the collected keywords by intent — informational, comparison, how-to, and so on. Even within one theme, different intents call for different content.
- 3
Check coverage with competitor headings & co-occurrence
Analyze the H1–H6 headings and frequently used words (co-occurrence) of top-ranking pages for your target keyword to find topics your content is missing. This reverse-engineers what Google considers essential for the topic.

Get ahead of follow-up questions with query fan-out
Generate the follow-up questions AI search engines (ChatGPT, Perplexity, Gemini) are likely to ask next from your keyword, and cover them within a single page — a coverage tactic for the AIO/GEO era.
Suggest vs. co-occurrence vs. heading extraction vs. fan-out
This tool offers four keyword research features. Each differs in what it reveals and when to use it.
| Feature | What it reveals | When to use |
|---|---|---|
| Bulk Google Suggest | Related keywords people actually search | Surfacing article themes and long-tail candidates |
| Co-occurrence extraction | Words that appear often on top-ranking pages | Checking topical coverage and finding missing terms |
| Heading extraction | The H1–H6 structure of competitor pages | Reference for article structure and heading design |
| Query fan-out | Follow-up questions AI search may ask | AIO/GEO optimisation and FAQ design |
How much keyword research you can do for free
Bulk Google Suggest collection is available up to 5 times per day with just a free account — no installation required, and results appear instantly in your browser. Heading extraction, co-occurrence extraction, and query fan-out require the Entry plan or above.
An honest note: The tool only collects candidates. The final call on which keyword to write for and which intent to serve must be made by a human who understands the target reader. Rather than stuffing in suggest keywords and co-occurrence terms as-is, weaving them into content that solves the reader's problem is the prerequisite for being valued in both SEO and AI search.
