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.
