Landing pages seem to be the cornerstone of online marketing especially those who are running paid adverts for their online businesses. But the beginners will always ask that do you always need a full-blown website to create one? I've been thinking if there's a way to skip the rigorous of building a site and go straight to a stand-alone landing page. 

Are platforms like Leadpages, Carrd, or Unbounce the answer? Have you tried creating a landing page without linking it to a traditional website? I'd like to hear about tools or services that make this possible. how effective they've been for your campaigns.
