When your blog is doing really good and gets hundreds of visitors a day, that is not the time to get lazy with your work and keep on expecting to get hundreds of visitors to your blog every day. Your visitors will eventually catch on with the fact that you do not update you content. When they catch on to this, they will seek other sources of information. If you update your blog everyday when it has close to 0 visitors a day, then it is too late and you might as well start over. Keep on updating your content to keep your visitors and make sure that more visitors come as well. If I didn’t update this blog for a week (or even a month, but that will never happen), I would lose a lot of visitors because people who visit other people’s blogs want to see quality content, not a blog that had its last archived post in 2012.
