How to Increase website traffic

Today I want to ask to you all that can we increase website traffic with in few days but when we talk about increase website traffic, we're really talking about several different things, including increasing hits, increasing page views, increasing page loads , and increasing unique visitors. For some sites, increasing page views will be the immediate goal because the concern is that the vast majority of visitors view only one page of the site, then leave. For others the immediate goal will be to increase the number of unique and return visitors.
