Positive online recommendations can boost the price consumers are willing to pay by an average 9.5 per cent, found a study released yesterday claiming to be the first of its kind.
Negative recommendations meanwhile can reduce the likelihood of purchasing a product or service by up to 11 percent, said the study commissioned by the social data company ShareThis and The Paley Center for Media.
The study highlights the theoretical value of sharing on social media instead of the actual impact on prices.
"This is the first time someone has tried to quantify the value of recommendations and sharing," Abrahamson told AFP.

"If you are able to generate positive buzz, it does have a significant value."
The study, to be released at a conference in New York today, indicates that online recommendations influence consumer purchases more than price and brand, and carry nearly as much weight as face-to-face recommendations.
"We've all known that social sharing is important, but it's been difficult to measure its impact on consumer spending -- until now."
A key finding is that positive online recommendations enable manufacturers and retailers to charge more.
The impact can range from less than a dollar for grocery items to around USD 30 for technology produces and upwards of USD 9,000 for an automobile.
The report examined several types of online sharing, including personal recommendations via email or social networks such as Facebook, Twitter, Pinterest and LinkedIn; recommendations of websites like Yelp; in-person or face-to-face recommendations; and professional reviews.
