There are no set rules on what is the best practice when starting a blog, its very much up to each individual to adopt their own writing style. A new blog is best started with placing some interesting posts to kick start your content writing, say per perhaps half a dozen article and then add posts every day.
You are going to be doing a lot of writing, so I hope you have done your research well and know everything there is to know about what it is your blog is about or what it is you are selling. By the end of the first year your blog will be looking good with around 300-400 entries, at this stage maybe you will reduce the frequency with which you post to your blog, hopefully, not because you have run out of material, but because people are responding and the blog is successful and you need to spend more time developing more income or starting other projects.
A mistake some people fall into is to place short sales posts in their blog and these can actually become annoying. You need to provide the answers to what customers are looking for, so that they will interact you and wish to earn more by subscribing to your information.
Many people like to build their blogs on wordpress because its easy to use and has lots of plugins but I discovered that every pluggin you use is providing free links from your sites to the developer so I moved away to the free blogging system provided by MarketHive, yes there are no plugins however due to the way the blogs are integrated with a custom designed marketing system each of my post gets 2,000-5,0000 plus views which I find quite incredible.
