A disadvantage of digital advertising is the large amount of competing goods and services that are also using the same digital marketing strategies. For example, when someone searches for a specific product from a specific company online, if a similar company uses targeted advertising online then they can appear on the customer's home page, allowing the customer to look at alternative options for a cheaper price or better quality of the same product or a quicker way of finding what they want online.
This definition emphasizes the focus of marketing on the customer while at the same time implying a need to link to other business operations to achieve this profitability. Yet, it's a weak definition in relation to digital marketing since it doesn't emphasize communications which are so important to digital marketing. In Digital Marketing Excellence my co-author, PR Smith and I note that digital marketing can be used to support these aims as follows:
There are many entities that need Internet marketing, but only budget a small amount for the work. If you’re willing to volunteer or offer a discounted rate, you can find projects. Non-profit entities and political campaigns need marketing help, but don’t have much money budgeted for the work. These types of organization may present an opportunity for you.
