I love this little Facebook campaign by Renault in Holland to help a Grandma find her missing car key. People left tags and tips on where it could be in her home and the Facebook likes to their page doubled during the campaign increasing by more than 27,000. A brilliant idea and nice little application – I would love to do something similar for our clients. If a client has the budget to do something fun and a little bit off the wall they can often get a great result and generate good awareness for a brand.
