Unless you don’t want your friends to know that you blog a great way to promote your blog without any extra effort is to put a link in your email signature.
If you have a blog you probably send an email at least once a day. That adds up to a lot of emails over the course of the year. If on every email you have a link back to your blog you’ll have one more link for people to click through and visit your site from.
It’s free advertising that’s subtle but effective. Of course you can be and should be selective to who you include in this form of free advertising, you might not want everyone to know your obsession with little toy trains, but every little bit of traffic helps build a more reputable blog and will help you build your readership.
Heck you might not even know that your good friend Larry has a blog of his own and might be interested in sending some of his readers traffic your way. Free promotion without any time or extra effort.
