Your blog is a great platform to launch a contest. Share one of your products, and allow readers one entry per day throughout the contest.
By requiring users to sign up with their email to enter into the contest, you’ll receive quality contact information. Just remember to provide these participants a way to opt out of future contact.
To keep customers returning to your blog, give them a reason to keep checking it. For example, you can provide clues within the blog as a means of winning the contest.
Additionally, setting up a contest with another company’s product is a good idea if you’re trying to reach a broader audience. Be aware, though, that some common items are associated with spammers, so choose your product (as well as your contest) wisely.
