Visit a handful of online marketing websites and blogs and you’ll get an idea of the emphasis being placed on the various activities near and dear to marketers’ hearts.
You’ll find a lot about search engine optimization, in spite of the howls of people who say SEO is dead. (They’re wrong.)
You’ll find plenty about the benefits and rise of social media.
And you’ll find tons of information on content marketing.
But you can go for quite a while without finding a meaty page or post about link-building.
