My first try did generate results with KPIs.
But two other tries did not generate any results, when I open the results page after "success" status is displayed, there are no keyword suggestions, only "no data found".
The 3rd try was "comment protéger les enfants" (how to protect children), which is definitely not long-tail to the point of not generating anything ???

Please could you explain what happens ? what I should be doing differently ?
