Except that those have definable effects, or at the least can be based in definable problems. "By using $SEO_technique, we were able to move up to $position in searches for 'blah blah blah'" "Our projects currently run over budget by $ugly_number and blow past their deadlines by $uglier_number. We need better project management to fix this." What's a similar "here's how UX/lack thereof is making your life easier/harder" story? It doesn't have to be abstract, it's just commonly being presented this way. Breaking it down into something like "an A/B test showed that people hit the download/purchase button $magic_unicorn_percentage more times after this kind of design change" can easily put the importance in terms that anyone at any level of management can understand.
