I have a websites that has 600+ pages indexed on Google yet I only have very little traffic from Google (3-5 visitors per day). No pages have articles that are in duplication as all are uniquely written. The website is specialized on one subject. Have any one encounter this problem? What may be the problem of my website? I know the need to reveal my link for better answer but I am sorry that I cannot reveal it.
Being indexed on google doesn't means you will have lots of traffic from it. Try to work in on page optimization for a better result in SERP and for your site to have traffic from organic
SERP is search engine result pages, it is ranked based on Google's algorithm. Organic is a term where your sites gain traffic from normal searches from search engines.
