Lots of content already is available online, so you shouldn't feel obligated to add massive amounts of material to what already exists. Chances are your individual audience members can only offer you limited attention, anyway. If you find yourself continually struggling to produce large amounts of content, chances are the quality won't be consistent. Later on, after you've perfected your system for generating great content, you can experiment with expanding your offerings or increasing your frequency. Let quality determine frequency.
Many online publishers feel pressured to update their content monthly, weekly, or even daily.
The ideal interval for adding new content depends on who you're trying to reach, and what goals you want your online venue to accomplish. This approach will yield a rewarding online venue regardless of whether you publish fresh content daily, quarterly, or rarely. Budget adequately for content. Too many online publishers make the mistake of underestimating the resources required to create quality content. When planning how to spend your money and time, separate out the resources required for content from those needed for design, programming, marketing, and so on.
