Timing of posting your blog depends on the market and type of blogs you are doing. Like if your blogs deal with current events, news or trending topics. The sooner you get the articles out the better due to its newsworthiness. Timing here is essential as it is “hot†topic, time sensitive. Coming in a bit too late loses its value, quality and can just be regarded as jumping on the bandwagon unless regarded as “totally different†from what were already published.
For most blogs, the quality of content is deemed more important rather than frequency of posting but done on a regular duration. If you publish your posts once a week, your followers will be expecting to read new posts weekly. If you can produce once a day, you are expected to at least post once a day on a regular basis. Here timing is best usually during daytime 9a.m.-5p.m. when most people are already awake either at work, in school or at home.
There is actually no standard practice for scheduling posting of your blogs. It depends on many factors and vary from blogger, the publisher and the reader. Just continue to delight your readers with your relevant interesting topics and sustain this momentum by providing them , if possible, proper expectations on release of new articles.
