One free tool of mine brought in €773 in revenue in its first six weeks of orders. The search words that fed it sat right next to the product, not on the product itself. This prompt finds those words for your niche, in every language you can serve.
From the video about that tool. €773 is revenue, not profit, and October is also the start of gift season, so it doesn't prove the tool did it alone.
Fill in the three lines at the top and paste it into Claude, ChatGPT or whatever you use. It gives you a list to check. It doesn't give you numbers, because a chatbot doesn't have them.
I sell: [your product, in plain words]
Who buys it: [one sentence]
Languages I can really serve: [for example English, German, French]
Find the free tool people search for right next to this product.
1. List 10 phrases people type when they are ready to buy this product.
2. List 30 phrases people type when they want a free tool for the same job.
Use words like generator, maker, calculator, checker, converter, estimator,
planner, visualizer, template. Only suggest a tool I could really build.
3. For each language, write how a native speaker would type these phrases.
Don't translate word for word. A German searches "laminat berechnen",
not "laminat rechner kostenlos online tool".
4. Don't guess search volumes. You don't have them. I'll check them myself.
Output one plain list per language, one phrase per line, nothing else,
so I can paste it straight into Google Keyword Planner.I tested this on 30 October 2026 on laminate and vinyl flooring, so I couldn't lean on anything I already knew. 40 phrases went into Keyword Planner across the US, Germany and France.
| Market | Phrase | Type | Monthly searches | Competition |
|---|---|---|---|---|
| US | laminate flooring | buy | 110,000 | High |
| US | flooring calculator | tool | 5,400 | Low |
| US | flooring square footage calculator | tool | 2,400 | Low |
| US | laminate flooring calculator | tool | 1,900 | Low |
| Germany | laminat kaufen | buy | 3,600 | High |
| Germany | laminat berechnen | tool | 140 | Low |
| France | parquet stratifié pas cher | buy | 720 | High |
| France | simulateur parquet | tool | 70 | Medium |
So a flooring calculator is a real candidate in the US. The other languages are much smaller here, and that's the point of checking: 6 of the 40 phrases came back with zero searches, three of them in French. I'd build for English first and add German later.
Keyword Planner has one trap. "floor plan maker" and "floor layout generator" both showed exactly 33,100. Two phrases with the same number are most likely one group of searches, so don't add them up.
Search volume is Google's estimate, and it says nothing about whether a visitor will buy. My own tool had 71 clicks and zero orders in its first full month. The keyword gets you the visitor. The tool has to do the job, and the offer has to sit right after the result.
On that tool, English-only research also missed most of the traffic: in October about eight in ten Google clicks went to the other eleven languages. Your niche may differ, which is why step three of the prompt exists.
More setups from the videos are in the guides, like keeping your Search Console data in BigQuery, so you can see which of these words start bringing clicks.
