If you have a blog that you are particularly proud of,and that you want to share with other people, there are a lot of free ways that you can get your blog noticed.
One of those ways is something that you do everyday,and that you may not even consider as a way to share your blog. Put the link to your blog in your email signature.
Chances are that you send out emails more timese that you can count during the day, Each time you send out an email, you can advertise your blog by putting the address of your blog in your email's signature.
It's always a good idea to write something catchy like, See what I am up to now, or Read my latest chapter of my fanfic here, depending on what type of blog you have.
The thing to remember about putting an adveritsement in your signature for your blog is to make it short,but eyecatching.
You want people to be interested enough to want to click on it, but you also don't want to scare them off. Just like it is with any adveritsement, you want to give them just enough to be interested and take a closer look at what it is that you are advertising.
Think about what it is that your blog is about. What is really going to interest people abuot it and want to visit? That is what you should include in your signature, and that is what is going to get people to go to your blog.
