If you don't update your blog often enough, blog readers will move on to other blogs. There are too many blogs out there competing for attention. Blog readers will go where they can get enough of what they want.
Successful blogging takes a commitment of your time. When you begin blogging and wish to capture an audience, you should be prepared to blog every day. In this way, you can develop an audience who counts on you to help them begin or end their day.
This means you should also try to post at the same time each day. Your readers will get accustomed to your schedule and check your blog at the appropriate time. The time of day is not as crucial as the consistency in your posting.
Since you now have quality content and a regular posting schedule, it’s time to drive traffic to your blog. Your readers will do a lot to promote your blog just by telling their friends. Don’t count on this alone! You need to do some additional work.
When you post, make sure you set your blog to "ping" blog tracking sites every time you add a new post. Think of this as a means to get their attention. The ping says “Hey, we just added a new post”. An alternative to automatically pinging from your blog is to use pingomatic.com. This is a one-stop place to automatically ping everyone you should notify of your new post and only takes a couple of minutes to accomplish.
