Every keyword list, no matter how large, starts as roughly ten short phrases. Get those seeds right and the tools do the rest, get them wrong and you industrialize the wrong garden.
Here is how to find them from absolute zero, and the quick tests that catch bad seeds before they waste an afternoon.
The seed zone
Five sources, in order of quality
1. Customer language. Emails, reviews, support chats, sales calls. Write down the nouns customers use for what you sell, in their words. "Cold brew jar" beats your catalog's "immersion vessel" every time.
2. Your products and services, translated. List what you offer, then rename each item the way a stranger would ask for it. The translation step is the point.
3. Competitor navigation. Three competitor sites, menus and category pages only. Every menu item is a seed they considered worth structuring a business around.
4. Category logic. For each seed you have, ask what sits beside it, above it and below it. Cold brew sits beside iced coffee, under coffee brewing, above cold brew ratios.
5. One AI brainstorm, filtered. Ask ChatGPT for subtopics of your niche, keep the topics, ignore any numbers, and run every suggestion through the tests below before it earns seed status.
The three seed tests
| Test | How | A seed fails if |
|---|---|---|
| Autocomplete test | Type it plus a space in Google | Suggestions are sparse or off-topic |
| Ownership test | Ask: could we credibly rank here? | It is another brand's name or turf |
| Direction test | Expand it briefly | Expansions belong to a different business |
The autocomplete test is the workhorse: rich, on-topic suggestions mean real demand in your customers' phrasing. Silence means the phrase lives only in your head.
From ten seeds to a real list
Once ten seeds pass, expansion is mechanical: run them through the keyword tool on this site and hundreds of long-tails stream out free.
Then the standard pipeline takes over: numbers, intent, difficulty, targets. The whole flow is our 7-step process, and seeds are step one for a reason.
Keep the seed list alive: new products, new customer phrases and new competitor menus feed it. A refreshed seed quarterly beats a hundred stale expansions.
The one-line takeaway: seeds are the ten short phrases your whole list descends from. Harvest them from customer language and competitor menus, test them against autocomplete, and let the tools do the multiplying.
