If you write a blog often, you can run out of ideas. In 2011 I suggested a simple exercise: type a topic into Google and watch how searches are completed. For a cycling blog, you might begin with “bicycle”, add letters and see what more specific questions appear.
This can still reveal words and questions you would not have thought of yourself. A suggestion, however, does not prove that a topic has much search traffic or that your readers care about it. Record interesting patterns first, then investigate the need behind the query.
Turn a suggestion into a good question
Start with a theme that fits your knowledge and audience. Try variations beginning with “how”, “why”, “when” or “how much”. Notice which questions recur and which are merely different wording. My old article suggested going through the alphabet. That can still be a brainstorming exercise, but you do not need hundreds of combinations to find one good idea.
Then open the results for a few promising questions. What is already explained well? Where are practical examples, current information or a useful distinction missing? Write only when you can add something. An article that places a suggestion in its title without genuinely answering it does not help anyone.
Stay close to your experience
Search behavior can inspire you, but your knowledge determines what you can explain. A customer question or a problem you solved yourself is often a stronger starting point than a random popular term. Use suggestions to check how people describe that problem. The title can then speak their language without letting an algorithm dictate the content.
