To embed you the giveaway into your blog or website, you must past the "embed code" directly into the html of your webpage.
First, you'll have to copy the embed code. It can be found in two places.
1) In the "Giveaways" tab of your account, there will be a link under each giveaway that says, "Embed Giveaway In Your Site". Click that link and copy & paste the code snippet from there.
2) The page you're redirected to after creating or updating a giveaway. Copy & paste the code from here.
After you've copied the embed code, you'll need to paste it into the HTML of your webpage. This is an example of how it looks on Wordpress blog. NOTE: you have to paste in the HTML. Most editors have two setting for their text editors: a regular part, and a part where you can put code into. Be sure to put it into the part where you can put code.
If you're unsure where this is, you should contact your provider. Otherwise you can contact us at support and we'll be more than happy to help you out :)
