Finding Paying Customers Abroad Starts with Google Suggest, Not an AI Chatbot

Shipping an AI-powered tool is cheap; shipping one nobody searches for is the real cost. This workflow replaces speculative prompting with demand signals pulled directly from search behavior, giving solo builders and small teams a repeatable way to validate before they build.

Summary

Brainstorming with an LLM tends to produce plausible-sounding but commercially hollow ideas — tools nobody searches for or that already have mature competitors. A more reliable path starts with Google Suggest: feed a root keyword into the search bar, cycle through a–z prefixes and suffixes, and harvest the autocomplete suggestions. Those are real queries from real users.

Root keywords aren't dictionary words; they're user actions — generate, calculate, convert — paired with output formats like PDF, image, text, or video. That combinatorial matrix produces a first batch of candidate keywords. Each candidate then gets expanded through Google Suggest again, and high-ranking tool sites are mined for their own SEO keyword clusters, creating a self-reinforcing loop of word-to-site-to-word discovery.

The whole process can be automated. Google Trends data comes in via RSS, Google Suggest has a callable API, and an agent like Hermes can be configured to crawl daily, filter viable tool-site keywords, and deliver a curated list every morning.

Takeaways
AI-chat-generated product ideas often describe tools nobody searches for or that already have dominant incumbents.
Google Suggest autocomplete reveals real user search queries when you cycle a–z before, inside, and after a root keyword.
Root keywords should be user actions (generate, calculate, convert) combined with output formats (PDF, image, text, video).
High-ranking tool sites are SEO goldmines; mining their internal keyword links turns one candidate into many.
Google Trends surfaces rising search terms that can be filtered for tool-site potential.
An AI agent can automate daily keyword crawling from Google Suggest APIs and Google Trends RSS feeds.
Conclusions

LLMs are poor at demand discovery because they lack access to live search-volume data and competitive landscape signals; they generate ideas that sound right but carry no market evidence.

The combinatorial matrix of action verbs × output formats is a lightweight but effective substitute for formal keyword research when you have no budget for tools like Ahrefs or Semrush.

Automating the workflow with an agent closes the gap between a one-off brainstorming session and a continuous demand-sensing pipeline, which is closer to how professional SEO teams operate.

Concepts & terms
Root Keyword
A seed term representing a user action (e.g., generate, convert) rather than a static noun, used to initiate demand discovery through search autocomplete and keyword expansion.
Google Suggest
Google's search autocomplete feature that predicts queries based on real user search behavior; cycling through alphabetical prefixes and suffixes exposes a wide range of actual search demands.
Keyword Cross-Pollination
A discovery loop where a candidate keyword leads to a high-ranking site, whose own SEO keyword clusters reveal new candidates, which in turn lead to more sites.
