One super-easy way to drive more traffic to your blog is to use your email signature. If you're like me, you send tons of emails every day, many to people who may not closely follow (much less subscribe to) your blog. Why not help them find your content? (And if you're in a big enterprise, encourage everyone to spread the word this way.)
Why am I doing this?
Before you do anything, know why you're doing it. What's your purpose? I want people to click, of course. But more than that, I want them to see that I've got something to say or a solution to a problem. The posts in my signature should make people say, "hey, there's some information I can use or a topic I want to know more about". (Read more about finding your purpose here).
What should I include?
My general rule is to put the most recent blog posts in my signature because different topics appeal to different people. Sometimes, though, I might choose a range of posts that cover a particular topic, like content development, that I'm trying to promote. And I always aim for no more than 3 to 5 posts. Otherwise I might come off as "hey, look at me!", which isn't what I want.
Here's the current version (which hasn't been updated to include this post yet!):
How often should I change it?
I update my signature daily, but you don't necessarily have to. And if you don't want the hassle of updating with specific posts, just put something as simple as "Read my blog!" or "Get tips on X here". Keep it simple and inviting.
Give it a try and let me know how it goes.
