Study shows that well-edited hometown wiki entry will attract tourists

Imagine you live in a small town in the middle of nowhere, but it has many natural and cultural attractions. You wish to attract more tourists and promote your hometown's economy through tourism.

What do you think is the most cost-effective ways of publicity and promotion? Hire a celebrity for advertisements, or simply become a social media influencer of short video yourself?

In fact, carefully edited hometown's Wikipedia entries is one of the most cost effective way to attract tourists to your hometown.

An experiment carried out by economists at Collegio Carlo Alberto in Turin, Italy, and ZEW in Mannheim, Germany, found that a simple edit of a Wikipedia page could potentially generate an extra £100,000 a year in tourism revenue for a small town - highlighting the potential social benefits of a free online encyclopaedia.

Researchers randomly selected Spanish cities and targeted them, improving their Wikipedia entries, adding descriptive information about history and local attractions, as well as high-quality photos. 

No experts were required. Most of the added content was simply translated from the Spanish Wikipedia into French, German, Italian or Dutch.

The results are immediate: adding just two paragraphs of text and a photo can increase the number of people staying in the city by about 9% during the peak tourist season. In some cases, the increase was even greater. For towns that have little to no content on their Wikipedia page, adding just a bit of content can boost visitor numbers by a third.

"If this were extended to the entire tourism industry, it would have a huge impact." Authors Marit Hinnosaar, Toomas Hinnosaar, Michael Kummer and Olga Slivko write, "The economic impact could be in the billions of euros." 

In fact, the impact is so large and somewhat frightening that it raises the question of why most of the world's cities don't take the initiative to maintain their own entries. Wikipedia content is largely written and edited by volunteers, but simply increasing the amount of available information on certain topics relative to the time spent can pay off big time.
