Paid search advertising costs money, which at first may seem like a disadvantage, but these costs can easily be managed. With cost-per-click (CPC) or cost-per-thousand-impressions (CPM) campaigns, you spend as much or as little as you want. You can adjust your campaign budget at anytime, so if your business is going well, you can spend a little extra to drive traffic to your website and catch the attention of new customers.
Social is no longer just about conversation and content; it’s now an established channel for customer acquisition, remarketing and engaging existing fans/customers to support retention programs. It may be relatively immature compared to search and email marketing but it’s a channel in which most ecommerce teams are ramping up investment (people and tools).
