FAQ

Are these real searches? Yes. Autocomplete suggestions come from what people search for on Google or YouTube. They're a great signal of real demand, but they don't include volumes unless you turn on the metrics add-on.

Why do I get fewer keywords than "Max keywords"? Some seeds simply have fewer distinct suggestions. Add more expansions or turn on Deep expand.

Does it need proxies? No setup needed. If Google rate-limits a run, the Actor slows down and retries automatically.
