Nielson have just confirmed that Referral and Word Of Mouth marketing still leads the way as the most effective way to gain more customers
Friends recommendation twice as effective as consumer opinions
60 people out of 100 are likely to take action from a friends recommendation compared to 25 for an email that somebody has signed up for.
Text ads on mobile phones you are down to 4/100. In fact when we spoke to our customers their clients indicated that if they got a text ad not only would they not respond but they may avoid that brand in the future, so you have been warned.
The takeaway I see here, is its clear you want to educate your customers and ensure that they have a great experience that they want to share with friends or talk about in social media. So business as usual.
