For 15 years, IT&IS Siglo XXI has been administrating well-known websites such as online magazine euroresidentes.com and cooking recipe resource misrecetas.org, and for 10 of these years it has been profiting from hits using Google AdSense. This advertising tool has become the company’s primary source of revenue, and has allowed it to significantly increase staff levels. “Rebecca and I launched a website for foreigners living in Spain. The company grew, our entire family got on board and now there are 20 of us,” says Andrés Pedreño, Co-founder of IT&IS Siglo XXI. “Our company has grown thanks to AdSense.” Moreover, with the help of other Google products like YouTube, Analytics and Webmaster Tools, the company has seriously raised its profile in Latin America and the United States. This in turn has enabled them to sign major collaboration agreements with Japan’s most-visited recipes website, and with a Chinese graphic design company.
