This is a story I tell quite often. My job is website optimization and customer experience. In most companies it would be incredibly unlikely that those two roles would sit in the same department let alone the same team. In our maturing Digital Marketing team however it makes a great bit of sense. I'm able to advocate for decisions on our website on behalf of both the user and the engines - which more and more overlap by quite a large margin. While not strictly UX - we do have UX designers on our production team within Digital - CX looks an awful lot like UX in many instances particularly when concentrating primarily on digital engagement and interactions. As I continue to build out my team I'll grow up specialists in the disciplines somewhat separately but there will continue to be a great deal of overlap as they will be marching to the same objectives and goals. From a challenge perspective it all comes down to measurement. The ways in which you communicate CX and SEO wins are different and telling them in a cohesive story has proved an active of poetic acrobatics but we're working on it
