All marketing strategies will result in poor click-through rates over time.
Here’s a real-life example — let’s compare the average CTR for a banner ad that debuted on HotWired in 1994 and on Facebook in 2011:
Hotline hits , 1994: 78%
Facebook click-through rate , 2011: 0.05%
That’s a 1,500x difference. While there are many factors that influence this difference, the basic premise is sound—the click-through rates on banner ads, email invitations, and many other marketing channels on the peru mobile database web have been declining every year since they were invented.
Here’s another channel, email open rates over time, according to eMarketer:
While this graph shows the decline, another graph which I don't have handy shows that the number of emails sent per day has increased by over 3 billion.
All of these channels are declining over time and what saves us is that new marketing channels are constantly being unveiled. These new channels offer high performance because of lack of competition, huge opportunities for new marketing techniques and nowadays the cutting edge is optimizing your mobile notifications, not your banner placements.
