Back when I began my first blog (It was called "Confessions of a Keyword Concubine"), the prevailing wisdom was that writers should post every day, or at least every week day.
The Daily Approach--Pros and Cons
There were some pros to posting daily. First, the daily posts proved to clients that you were capable of maintaining a rigorous schedule. Second, thinking of new things to write about every day was an excellent form of self discipline. Finally, offering a fresh post daily was a great way to draw regular readers to my site. They would drop in several times a week just to see what was happening. Many of them left encouraging comments which were music to my newbie blogger's ears (well, eyes).
Daily blogging wasn't all paradise, though. There were some significant cons. It was really hard to think of something new to say every single day, and it was all too easy to start regurgitating my own posts or ideas from other websites.
Another problem was the time factor. As I started to get more paying gigs, I had less time to devote to coming up with daily blog posts. I decided it was time to try a new method.
