I disagree that any specific advice will help an individual marketer...I think the biggest issue is that the economics of acquisition on social (factoring in internet marketing budgets and customer LTV) doesn't work well for brands that aren't already operating at significant scale. Otherwise, Teespring would be a billion dollar company by now ;)

My guess is that social marketing works ok for brands that have a strong competitive position AND healthy margins.

Healthy margins and product appeal moreso than competitive position.

Teesprings product offering is far too broad to benefit specific targeting which really just leads to low user intent, which leads to huge acquisition costs. No one gets excited for tshirts.

Products outside of these hugely saturated markets do amazingly well if you know what you're doing.
