A landing page is a web-page created for a certain goal, usually for lead generation, coming soon campaigns, get a quote pages, etc.
A landing page is determined to get conversions, that’s why it always has its “call to action”. It’s not distracting its visitors from the required action. It can also be a simple website with its different sections leading to a “call to action”.
A website is a few web-pages determined to help people to find what they are looking for. Website web-pages can have different purposes. Not necessarily each of them should have a “call to action”.
