You are just wasting your money if you are marketing your product or service without Testing whether the product is what people need or not. You are no-likely to grow if your product is not a market fit. So, the first step towards Marketing should be Making Sure that People Love your product. You can add analytics to measure customer performance on your platform. Conduct surveys, whether they loved your product or not, and check NPS(Net Promoter Score) – How likely are they to share your product with their friends and family. If you are entering a competitive market, you must come up with some USP(Unique Selling Point).
