I work primarily as a freelance translator, with a reasonable amount of work experience (10 years) I get maybe 2-4 job offers a week, some more serious than others.

The thing is, many of these are unprofessional (ghost after first contact, don't reply back to arrange interview etc) and a lot of them lowball (offering about half the industry rate, for instance)

My LinkedIn is fairly complete and comprehensive. I had a session with a marketing expert (well, she seemed legit, I checked out her website etc) and implemented some of her changes, but I didn't really see an increase in the amount of offers or hits.

Am I better off just spending my time elsewhere?
