[Editor's note: We've refreshed a previous version of this list for 2018—hope you enjoy!]

Growth hacking has been around for what seems like a century in internet time, and it was indeed 8 years ago that Sean Ellis coined the term and it started taking off.

Some of the earliest bloggers on growth are still the most influential, but some newcomers are gaining steam. And with an upswell in growth tools to market, some of the best ideas are coming from blogs hosted by SaaS businesses.

I personally spend a ton of time reading articles on growth hacking for inspiration and research. And after conferring with a handful of peers, I whittled down my list to the 21 best growth hacking blogs for you to follow.
