Getting people on and off a page via an affiliate link as quickly as possible cheats you out of a lot of value.

By focusing on the subscription I can automate repeat opportunity's for social sharing & user generated content.

This can lead to more traffic, new backlinks, higher rankings, rankings for long tail searches and so on.

Subscribers are also much more engaged with me and what I have to say.

This breeds much higher quality traffic, Charles Floate recently posted this which shows how much more engaged the traffic coming from my blog is compared to others-

So the next time a post features an affiliate link - it is much more likely your audience will convert into affiliate sales. And trust me, they do.
