What is the difference between Lazy Load and Google Page Speed Optimizer extensions?

There are two landing pages created for marketing purposes: Lazy Load and Google Page Speed Optimizer. However, both landing pages represent the same extension.

Regardless of the landing page, there are three optimizer versions that we offer:
  1. Google Page Speed Optimizer Lite: includes lazy load options only.
  2. Google Page Speed Optimizer Pro: includes lazy load, image optimization, code optimization, and AMP extension.
  3. Google Page Speed Optimizer Premium: includes all Lite and Pro features + AJAX Shopping Cart and Infinite Scroll extensions.
In short, Lazy Load is just one feature of the Google Page Speed Optimizer solution that could be enough for some customers. Therefore, we decided to split the extension and add the lazy load function separately.
