While there are hundreds of different marketing strategies, only one can bring in consistent sales from day one.
Social media advertising.
Most channels require significant lead time to yield an ROI (ex. content marketing)
Some channels yield quick results but not day in and day out (ex. influencer marketing)
And some channels are consistent but time consuming to dial in (ex. AdWords)
With social media advertising, you can have consistent sales coming in from the first day your website is live.
For modern e-commerce sites, the ability to immediately and consistently bring in new customers is a HUGE deal. Even if you can’t achieve net positive revenue on the initial sale, referrals, email marketing and customer retention can pay off extensively with every marginal customer.
