This one is a phenomenal example with the others put in there so brilliantly! By far, I think the reason why people ask questions in their blogs’ headline is, they want to give it the readers or seekers or searchers perspective mainly. Like we have CTAs on our landing pages, and sometimes even the one on our website’s sign up page is written that way. Perhaps the thought of having to win every website visitor, to woo all the readers, to convert every trial users are some of the causes here. What I insist as the solution to this misconception is, have a persona and target the specific group of interest, instead of having too many pointless spotlight!
