I wrote a post about How to increase traffic about 4 years ago and I explained that how a person can increase and make traffic to her/his blog or site . That post was my most shown post to visitors.At that time I did not know about if you leave your site or blog then you will lost your visitors and your page rank will decrease.It's really important to posting often on your blog ,it will help to save your visitors and your page rank. Experiences never get easy and it's really good to use others experiences to do our jobs.
