Good post, misleading headline. You have to pay someone to do all the things described in that post unless you want to invest a substantial amount of time to learn the trade yourself.
Btw. Neil Patel is one of the most well known search and social marketers.
I disagree. I think you can learn a lot of those things and do it yourself.
Of course but it takes time and effort. In case you already run a business it's cheaper to hire someone than to learn it from scratch.
