I rate the following "skills" as dubious...<p>-SEO : No actual control over outcomes, basing results on third party platforms subject to arbitrary change.<p>-SEM : No actual control over outcomes, basing results on third party platforms subject to arbitrary change.<p>-Social Advertising : No actual control over outcomes, basing results on third party platforms subject to arbitrary change.<p>-Analytics : Statistics usually skewed in favor of only the most brainless users, that do not understand how to block scripts or manage their cookies and sessions.<p>-Email/Push Notifications : Spam.<p>This kind of stuff is fluff and busy-work at best.<p>I'm sure there are plenty of graphs charting direct relationships between "x" and "y", in the land of "more is always better", but how many people does anyone know who's decision making has ever directly turned on one of these bullet points?
