In my opinion, a company can succeed without using the internet to promote itself. Although the internet is necessary for attracting valuable and large numbers of clients, it should not be relied upon only for promotions. I don't believe you need internet promotion if you provide offline services such as selling provisions, running a POS firm, or other small companies. However, whether you offer digital services or run another internet-based business, you will need to undertake some marketing to attract leads and consumers. Those who work as freelancers rely on enhancing their web presence because that is where they obtain the majority of their clients. Consider those that run websites and require visitors to their sites. They won't be able to rely just on offline involvement; they'll need to market their blog page online in order to attract a large number of readers and earn a decent amount of money. Online promotion is a great technique to get your business or freelance work off the ground. So, the answer to your question is YES, because internet-based businesses and employment require online promotion.
