The religious orders have been lured to the jobs website for nuns, which translates from Spanish as: "I'm looking for something more", as their numbers continue to slump from 6,695 in 1966 to barely 250 today.
According to the Guardian, the site features a video message with a women who greets potential recruits by asking if they feel their lives are empty and if they've ever considered the religious life. "Don't run away," she says. "You may have a vocation without even knowing it."
The social media recruitment drive, which also incorporates Facebook, WhatsApp and other social networks as recruitment tools, appears to have had the desired effect in some cases.
The Carmelite convent in Valladolid in north-east Spain has gained more than 200,000 visits to its website, more than 8,000 likes on Facebook, and 461 Twitter followers.
It also uses a WhatsApp account to reply to women's inquiries. The convent has also recently grown from 18 to 30 nuns and the average age has fallen to 35.
Among the new recruits are a boxer who was about to join the army but chose the Carmelites instead, an engineer who gave up a good job to join the convent and a guitarist from a heavy metal band.
