I recently saw a blog post in which the author was promoting a product as an affiliate (here's an explanation of affiliate marketing if you need it).
It was a great post in which they explained how they used the product and why they liked it. They sprinkled their affiliate link throughout the post appropriately and it was workin'.
…the last bit of their post was about Facebook.
Facebook was somewhat related to their post, but they said something like "Join me on Facebook!" and included a link to their Facebook page.
And that's where their post ended.
It made me sad.
Because they likely traded affiliate sales (income) for Facebook Likes (no income).
How are you ending your posts?
Think of the last paragraph or sentence of your post as your opportunity to guide your reader to the door of a next step (this is called a "call to action"). You can't control whether or not they will actually walk through the door you are leading them to, but that's the hope.
In this case, the author did a great job of leading me right up to the door of an affiliate sale. But in the very last paragraph, my attention was diverted to a different door altogether (their Facebook page)—a door that, unfortunately in this case, wasn't going to convert into much more than a "Like."
The moral of the story
Pay close attention to the end of your posts. What is the last link? Ask yourself what you want your reader to do next and make sure you do everything you can to lead them right up to that door. Hopefully they'll walk through!
