More and more traffic?
That's easy. Just put more and more content that your visitors like to read. Keep a close eye on your visitor stats. Note carefully which pages your visitors are viewing. Put more content of the same type. Keep track of developments.
Seriously speaking, it doesn't take rocket science to get more traffic. Just do some simple arithmetic. There are a few hundred million surfing the net at any one time. If only one in a million is interested in your website, you are talking about a few hundred visitors every day.
The main problem is that, most of the time, webmasters just fool themselves into thinking about all kinds of tricks to attract traffic to their sites. What they forget is that if they have content worth reading, the visitors themselves will spread the news.
