To do this, you first purchase a domain name, I usually use www.123-reg.co.uk.
search for a domian you want, and purchase it. That is the easy bit. The nesxt bit, you just need to set up what is called web forwarding, to forward your new domain to your elottery affiliate link.
Log into your control panel at www.123-reg.co.uk, Scroll down to the bit that says, modify domain, with your domain name next to it. and click modify domain.
Now click on web forwarding, and you want to select, framed forwarding.
Enter the details of your link in the boxes below, the url to forward website to, is the url of your link, which will be similar to www.v-w-d.com/189418ab, obviously put in your own address or they will be forwarded to my affiliate link
.The title to be displayed, for this simply choose the title you want for your website.
Fill in the Meta tag info, this info that search engines use, the description is what will appear on google when your link appears, and the keywords and words that should trigger your link to appear in the search results (although that can take time).
Then simply click Update web forwarding, and that should be you. officially it can take up to 24 hours, but is usually updated straight away.
