The first click is an important concept for sites with content. It means that when a visitor clicks on a content link (for example, out.php?url=http://gallery.com/post.html) for the first time on your site, they're directed to that URL.

You can set the first click in several ways:

1. Add the parameter &fc=1 to the link: out.php?url=http://gallery.com/post.html&fc=1
2. Set a default in Settings > CJSettings > Default first click
3. Configure individual trader settings under Personal click
4. Define it in each trader's Personal Trade Scheme

First click is a legacy option. Enabling it with 50% skimming is equivalent to the skimming sequence 100,50: the first click always goes to content, and subsequent clicks use 50% skimming. Likewise, if first click is enabled with 70,50 skimming, the initial 70 becomes 100, followed by 50% skimming.
