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.
Marketing is the key to selling, sometimes what I see some products do not have higher quality but can produce very large profits by using good marketing for people or consumers buying our goods, things like making our business become much better.
Especially if the products we sell are of quality, of course, if you have a very broad marketing and market expansion it will be very important for long-term business growth, but it also needs to be considered that consumer behavior has a cycle in certain times if you understand marketing .
