QUESTIONS

Questions about Topic demand.

It checks whether a topic has search demand, trend movement, AI answer coverage, and conversation signals before you invest in it.
/v1/trends is one primitive. Topic demand combines trends with keywords, AI search, and Reddit signals so the answer is not based on one chart.
Run the workflow once per topic and compare the returned results. Keeping one topic per run makes the evidence easier to audit.
Use it before choosing a landing page angle, content pillar, product bet, or client recommendation.
The topic-demand workflow runs keywords, trends, AI search, and Reddit. Use the YouTube Trends endpoint when video demand matters.
READY WHEN YOU ARE
