Is Automatically Responsive Content Really a Good Thing?

We know that sales conversion is dramatically better on desktop machines than on mobile gadgets. I talked about it a few posts ago. But knowing is one thing, and acting on it is another.
270% more sales are made on desktops than mobiles. It makes sense to tailor mobile friendly content accordingly, making it as appealing as possible by giving users exactly what they want and need at that stage in the sales process: the finding out stage. This would include adding the right kind of calls to action – something software doesn’t do.
Plenty of platforms automate the responsive process. Take WordPress. When you build a WP site the responsive side of things happens automatically. But is this always a good thing?
I would have thought it’d be much more sensible to have a measure of control over your responsive content rather than leaving such a delicate marketing task to software. Otherwise how do you know for sure that your responsive pages contain the content that people at the finding out stage most want and need to see?
Do you know for sure that the right desktop site content is being pulled through to small screens? Can you control what your platform does when it generates responsive pages? It’s worth finding out.
