Patience is the only “hack” that works. Traffic growth is slow (but steady).
Also, read extensively. Don’t just read about blogging/marketing, but also read for pleasure. I sign up to the MediaREDEF newsletter and NextDraft, and I make sure to take time out of my day, every day, to read about interesting topics. It’s been said time and time again, but reading makes a better writer.
When it comes to writing, focus on clarity. Proofreading is important, but more important is that your point is clear. Always opt for less in-depth, data-packed, helpful posts than more crappy content. Quality over quantity.
Build relationships with people in your niche. Don’t just try to promote yourself – give back to your community. Constantly ask your audience if the content you are writing is relevant for them.
