Branded Content vs Content Brand
If you're consistently producing awesome branded content that speaks to and engages your core audience without a sales pitch, you're already a content brand, so you might as well be strategic about it.
Your favourite content generation/marketing tools
I'm pretty good at coming up with ideas, but there are two tools I use a lot to test their viability. Buzzsumo works well for checking on content popularity and shareability, and CoSchedule's Headline Analyzer is useful for tweaking my planned content title.
#1 Social media channel for content marketing
Who knows? I still remember when MySpace was considered the future of social networking. The only thing that's certain is that whatever we think is great now will eventually give way to something else..
Long detailed vs short snackable content
Does it have to be a battle? There's room for both. Sometimes you need easily digestible content as a pointer to something with more depth you can check out later. The issue for content marketers will be working out which type of content their audience needs when, which means there's really no change.
The future of the Content-SEO pair
Content and SEO will always be joined at the hip, since SEO helps people find your content and good content gets more search prominence. However, no-one knows how SEO will change. SEO today is hugely different from SEO ten years ago - and ten years from now it may be even more different.
