This overview collects free, source-backed methods for checking what search demand looks like before you commit a publishing calendar. Each guide in the cluster names its data source, states its time window, and says what the method cannot tell you.

What this cluster covers

The first guide checks whether a topic is seasonal using monthly Wikipedia page views, with a chart built from real API data and a walk-through you can repeat for any topic. The second guide counts new questions per month with the Stack Exchange API and shows how to read a candidate topic against a stable control. Later guides will cover other demand checks on the same terms: named data, visible limits, and a method you can run yourself.
