Referers problem

As the description says i do not have information displayed in there. I’ve connected to my site through both google and yahoo search engines, but nothing shows up.

The referer is recorded on the initial visit. In your testing, you’ll need to clear your cookies.

I also notice referrers (websites, keywords) stopped recording after about a week.
Google analytics stores referers, piwik not.

I see traffic on the site (aprox 3600 unique visits)

  • campaigns are registered
  • visitors entry page is empty!
