I have one website for desktop that is designed for 1024 width and above. This means that some mobile devices in landscape mode will also fit this criteria. I have another website that is designed for below 1024 width, that means the same devices in portrait mode will show this instead.
Although this sounds like conventional responsive design, the 2 versions have very little similarities to tweak. It will be much easier to just do both version from scratch.
What is the way to go for this situation? Must be SEO and robots friendly for at least the PC version.
