We have talked about posting schedule a long time ago. We were not really focusing on niche blogs then but the general idea was to have a regular posting schedule. Does the same thing apply to niche blogs?
I would have to answer a resounding YES to that question. You see, niche blogs may be tightly focused on a specific subject but it does not mean that it is much different from other blogs. The idea behind blogs is to provide fresh content on a regular basis. It does not have to be daily, especially if you are maintaining several niche blogs. If you decide to post daily and you have several niche blogs, you might find yourself having a hard time juggling your posting schedule. In fact, I would say that posting every other day or even two or three times a week would be a good enough frequency for a niche blog.
Another consideration that you have to think about when it comes to content for your niche blog is the possibility of future posting. Basically, future posting is writing entries for your niche blog before you actually publish them. So for example, you can write the posts for the week on a weekend and then just pre-date them. With WordPress and Blogger, it is not a problem as they allow this. This idea is very important for those who have day jobs and other commitments. This means that they might not have the ability to set a regular schedule during the week.
The important thing is for you to lay down the guidelines for your posting schedule and stick to them.
