For two and and a half years Rev. Chris Lee's Instagram account grew steadily. He posted mostly pictures of himself, his family, and the church.
In July 2019 things changed. Chris started uploading “60 second sermons”, where he would distil some bible teaching into a 60 second chunk. The next five months saw him go from averaging 1,000 new followers each month to 10,000.

Here's a quick video of Chris in action. The format is wonderfully simple. It's also a great reminder of some social media fundamentals:
Chris’s “60 second sermons” give his account a clear purpose.
You can’t tell your friend, “You should follow this priest”. But you can say, “You should follow this priest... He posts these 60 second sermons”.
Instagram is for light entertainment. Chris's content reflects this.
He doesn’t preach from the pulpit. His “sermons” aren’t polished. He walks down the street holding an iPhone. That's what people on Instagram like to consume.
Chris records his sermons, uploads them for free, and never asks for anything in return. First his Instagram grew, and more recently his own congregation has grown as well.
That's how social media marketing works. People do not follow you to be advertised to. You can't force it. Consistently add value and people will check you out because they want to.
I'd like to share this tweet by Matthew Kobach:

Chris's “60 second sermons” look obvious. But, of course, it's only obvious in hindsight. Before Chris no one was doing it.
Chris's story is a reminder to experiment. Don't fall into line and post what everyone else is posting. Because for two and a half years you might be doing it one way, only to find, a much better way under your nose the whole time.
Thanks you for reading. If you find this sort of thing useful, I write marketing case studies (likes this one) over on Marketing Examples. Been doing it for a while now, and there's lot of practical stuff up there for Indie Hackers.
Thank you for sharing this, Harry. Great story, and actionable advice.
My Smash Notes podcast has been on hold for a few months because it's been rather difficult to find the time, but people have been asking for a return. Now I know exactly what I should do!
Thank you.
Cheers Kirill - I love Smash Notes btw :)
