Just make a URL and paste it into your site or blog. The pattern for your referral tracker will look like this:
samnashy.hubpages.com/[referral tracker name]/user/new if you want people to go to the sign-up page. If you want them to visit the hubs then it would be:
samnashy.hubpages.com/[referral tracker name]/hubs and so on.
Replace the [referral tracker name], including the square brackets with your actual referral tracker, say, _myreferraltracker with that leading underscore. If you just want to use your HP name then it would be _samnashy
If you want to make a referral tracker to one of your hubs then go to the hub and at the very bottom of the screen you'll see "link to this page" Click on that and you'll get a popup that has a pulldown menu at the top with all your referral trackers. Choose one and the URL is automatically made below and you can just copy-n-paste it.
I like to use a lot of trackers so that I can see where my traffic is coming from.
