The problem is whilst we know the difference, most employers don’t.
I’m personally sick of seeing adverts that have this long list of requirements, says you have to be “proficient” in all of them, yet really they need two separate people.
All you can do is specialize in one area, and be knowledgeable of the other. Then apply anyway, and at your interview perhaps you can then explain it to them.
A lot of employers need a website, but don’t know what their staff need to know to make it. So they just copy the “requirements” off another job, without realising that they’re actually asking someone to be able to do two different jobs.
