Writing blog posts is especially effective for providing different opportunities to land on page one of search engines -- for instance, maybe your eyeglass store’s website is on page three of Google for “eyeglasses,” but your “Best Sunglasses of 2018” blog post is on page one, pulling in an impressive amount of traffic (over time, that blog post could also boost your overall website to page one).
Apple maintains it’s viral appeal, with the iPhone X through their launch of the "Selfies on iPhone X" campaign. The secret to this example of viral marketing (which has clocked up over millions views both online and offline) is very simple: a product so great that it turns people into fans of the brand all on its own. People love themselves. If they have the possibility of spreading this love digitally through selfies, it’s almost a guaranteed win. The iPhone X’s brilliant selfie feature spread virally through various media forms before apple repurposed the viral content into one masterpiece, the iPhone X selfies film. As one of the YouTube comments says, “It’s the most beautiful thing I’ve ever seen”… This viral marketing through video has allowed Apple to spread key features such as their Portrait Lighting effects and their TrueDepth camera.
Just before launching in 2007, Dropbox created a virtual build: a 90-second video describing its services (and why people should pay for them) and asking for feedback. In doing so, they attracted 5,000 subscribers. After implementing customers’ feedback, they revised their product and released another 90-second video asking for feedback, generating 75,000 more subscribers in just one day. Once the product was finalized, Dropbox embarked upon an expensive marketing plan that resulted in unprofitable customer-acquisition costs.
According to a paper by Duncan Watts and colleagues entitled: "Everyone's an influencer",[66] the most common risk in viral marketing is that of the influencer not passing on the message, which can lead to the failure of the viral marketing campaign. A second risk is that the influencer modifies the content of the message. A third risk is that influencers pass on the wrong message. This can result from a misunderstanding or as a deliberate move.
