Digital marketing is a broad term used to describe a wide range of online marketing functions. As a whole, the primary goal of a digital marketing company is to do 3 things:
Increase your online presence.
Perform market research.
Integrate your online profiles and platforms.

When selecting an outside company to partner with, it is essential that you review what they create and distribute online. There is no one who knows your company and brand better than you, and you do not want to run the risk of inaccurate information being generated on your behalf. In fact, inaccurate online data has a negative impact on the bottom line of 88% of all companies—even if the inaccurate data was an honest mistake. The value of outsourcing digital projects is so high.

Global reach - a website allows you to find new markets and trade globally for only a small investment.
Lower cost - a properly planned and effectively targeted digital marketing campaign can reach the right customers at a much lower cost than traditional marketing methods.
Trackable, measurable results - measuring your online marketing with web analytics and other online metric tools makes it easier to establish how effective your campaign has been. You can obtain detailed information about how customers use your website or respond to your advertising. Web analytics can be set up to show you exactly how much money you make from each digital tactic.
Personalisation - if your customer database is linked to your website, then whenever someone visits the site, you can greet them with targeted offers. The more they buy from you, the more you can refine your customer profile and market effectively to them.
Openness - by getting involved with social media and managing it carefully, you can build customer loyalty and create a reputation for being easy to engage with.
Social currency - digital marketing lets you create engaging campaigns using different types of rich media content. On the internet these campaigns can gain social currency - being passed from user to user and becoming viral.
Improved conversion rates - if you have a website, then your customers are only ever a few clicks away from completing a purchase. Unlike other media which require people to get up and make a phone call, or go to a shop, digital marketing can be seamless and immediate.
