I have learned from experience that scaling any business is difficult. You may feel good when that first burst of customers arrives, but don’t assume that “word of mouth” and those early adopters will grow your business to match your dreams of success.
In these days of global competition via multiple channels, you need continuous marketing to find more customers. They won’t find you.
I continue to be amazed that more than a quarter of new businesses don’t even have a website, and many more don’t pay attention to social media, or monitor feedback on sites like Yelp.
