I'm taking a career advice course offered by my uni. One instructor strongly advocated for self-publishing a 20-ish page book on Amazon about whatever we want to find a job doing. I cannot think of a more embarrassing thing for an academic to do but I'm sure it works wonders for SEO.
My online presence is subpar compared to the chair of linguistics at Uni Stuttgart: I'm not on Google's 1st page of results for #linguistics, psycholinguistics, or cognition in Germany.
