Referral traffic means visitors coming from other websites, but they may not convert if their expectations are different. If the message on the source site does not match what they see after clicking, they may leave quickly. Sometimes the audience from that site is not interested in the offer at all. Slow pages or unclear content can also reduce conversions. Making sure the message stays consistent helps improve results. It is also useful to study where the traffic comes from, but what makes a good referral source?
