For the success of a business or enterprise, effective marketing is indeed needed even though quality products already exist. Too many focus on the number of followers without considering actual engagement.
Yes effective marketing of a business plays a vital role in taking the business to a higher level but then you may find people being clumsy over such matters, aside getting quality products making sure the business has more visibility to target audience and buyers is another criteria that is essential, and consistency in marketing also fuels the business to skyrocket.
I've been waiting for for someone to mention quality products, and yes, it's a good one, and good service is part of it. However, what I've noticed is that as good as the two are (quality/good product and service), they are secondary, what you sell has to be well-known first, that is what drives a business. Even if your customers are not satisfied, you have sold some and have made huge money through that, you lose nothing. Still, that is not smart and that's where the good/quality products and services come in. Anyone who wants to look beyond the marketing and the initial sales must have the two, as they are the factors that keeps customers satisfied, come back again and even naturalyl refer others to you.
