Shakespeare said that the course of true love never did run smooth; for eharmony, we set out to prove just that and how by using the service, with its unique matching algorithm, you can dramatically stack the odds of finding ‘the one’ in your favour.

Working with eharmony data scientists, experts from University of Bath and celebrity mathematician Rachel Riley, we calculated that singletons have a one in 562 chance of finding love on any given day. This was based on 18 key factors, such as desired age and physical attractiveness, which impact on the number of romantic options available to singles; and that by using eharmony’s compatibility matching system these odds are dramatically reduced.

We launched with a media relations push bringing together a number of assets to target different media homes. A broadcast day saw Rachel Riley conduct eight hours of back-to-back interviews, plus creative photography, a short video where she explains the odds calculation and a series of guest blogs were seeded across digital. Finally, an out of home element saw artisan cafes around London stocking limited edition cups displaying the odds of finding love in a coffee shop queue.

Odds of Love captured the media’s imagination securing 65 editorial articles with highlights including ITV’s Good Morning Britain, Channel 5 News, Mail Online, Express, Mirror, Metro and The Sun.

The campaign also drove a 10% boost in prompted brand awareness and a 21% increase in consideration.
