Refcontrol allows you to overwrite the referer url that your browser normally sends to webpages with whatever you want. So just put in your site address and browse the web normally. Keep in mind that this will, in some cases, annoy the crap out of people, but annoying the crap out of people is a benefit and not a drawback.
If you were so inclined, you could also write a curl script to go to random pages all day spamming your referer url all over the place. This will actually serve 2 purposes. First, as already mentioned, webmasters will check you out to see why you’re linking to them. Second, some statistics packages keep a public log of traffic, indexed by google. By spamming your referer all over the place, you will end up on some of these lists and generate backlinks for yourself. This is sometimes referred to as “Referer Bombing”.
