Dropbox was at least partially inspired by PayPal, which literally paid people money (through the PayPal system) if they got their friends to sign up. They did this because they benefited from the network effects of having large number of users- so even if half of the signups were people who just wanted the free money, the end result is a large number of people having PayPal accounts- which is a useful position for a payments company to be in.
As with offline advertising, industry participants have undertaken numerous efforts to self-regulate and develop industry standards or codes of conduct. Several United States advertising industry organizations jointly published Self-Regulatory Principles for Online Behavioral Advertising based on standards proposed by the FTC in 2009.[109] European ad associations published a similar document in 2011.[110] Primary tenets of both documents include consumer control of data transfer to third parties, data security, and consent for collection of certain health and financial data.[109]:2–4 Neither framework, however, penalizes violators of the codes of conduct.[111]
In the case of viral marketing, "viral" refers to something that spreads quickly and widely across its audience. Viral marketing is a deliberate enterprise, though the distribution of a message happens organically. As such, social media provides the perfect ecosystem for viral marketing, though it has its roots in traditional word-of-mouth marketing. While the practice was much more widely used in the early to mid-2000s, as new internet businesses were being created in extreme numbers, it is still common among internet-based business-to-consumer (B-to-C) companies. The widespread adoption of social networks, including YouTube, Twitter, Instagram, Snapchat and Facebook, has enabled modern viral marketing efforts and increased their efficacy. 
To create an effective DMP, a business first needs to review the marketplace and set 'SMART' (Specific, Measurable, Actionable, Relevant and Time-Bound) objectives.[61] They can set SMART objectives by reviewing the current benchmarks and key performance indicators (KPIs) of the company and competitors. It is pertinent that the analytics used for the KPIs be customised to the type, objectives, mission and vision of the company.[62][63]
As a note, referral marketing and affiliate marketing are similar in execution, but slightly different in concept. In the case of referral marketing, you’re asking existing customers to reach out to their established networks. Affiliates, on the other hand, operate solely for the financial benefit of sending you sales. One or both may be appropriate for your company.
To start Viral Marketing, companies use ‘seeding’. A seed is planted, it grows, creates new fruit with seeds that subsequently distribute its seeds. That means that a marketing campaign gets a nudge in the right direction; people are actively informed about the new campaign via social media. They’re stimulated to watch the expression. That gives the originator influence over the direction and the result of the viral marketing campaign.

We have a saying that “good data” is better than “big data.” Bid data is a term being thrown around a lot these days because brands and agencies alike now have the technology to collect more data and intelligence than ever before. But what does that mean for growing a business. Data is worthless without the data scientists analyzing it and creating actionable insights. We help our client partners sift through the data to gleam what matters most and what will aid them in attaining their goals.

In cases 3 and 4, even though Bob doesn’t buy the product, he’s now aware of it. The brand and/or product has entered his consciousness. It might be something he returns to in the future. If he likes the idea of it enough, he might talk about it to other friends in the future (“Oh, you like comedy? I’ve been meaning to watch Monty Python, and it looks great.”
It is increasingly advantageous for companies to use social media platforms to connect with their customers and create these dialogues and discussions. The potential reach of social media is indicated by the fact that in 2015, each month the Facebook app had more than 126 million average unique users and YouTube had over 97 million average unique users.[27]
There are many ways to determine which efforts are producing results and which ones aren't. For example, you can study your website's analytics through your web host or by using Google Analytics. Most social media sites provide analytics as well, or you can use tools such as HootSuite to get social media analytics. Your email service should also provide you with information on the open rates and engagement rates for your emails.
