The basic landing module is generally used for 10-second creation of landing pages, video subscription and full width video pages, and form pages (such as the fact form). With the update, assets such as those ridiculous stepped quizzes used by the leadgen crowd may be applied with a single click (part of the reason we object to the typical leadgen solution is that the form can be built and applied to a landing page in seconds).
The 'Advanced' landing pages will be sent to your website as editable pages, while the Yabber landing pages remain a Yabber resource. More information will be made available in the FAQs when the features are updated.
The last couple of months had seen significant updates after reduced FB effectiveness - its what happens when the market is flooded with illegal advertising.
We recently challenged a leadgen guy to an old and retired industry challenge (basically a competition with my 10-year-old daughter where he has 12X longer to produce a campaign). He obviously declined (after agreeing publicly), and it's tools like this he just couldn't compete with. His rubbish lead cost is generally higher than our conversion cost.
It needn't be said, but conversions shouldn't be focused exclusively on landing pages. Every page on your website is a potential entry point making it a 'type' of landing page, so every page should have a clear conversion-focused objective supported by good education.
