Adding a giveaway to WordPress is simple with the help of a plugin like RafflePress. To get started, install and activate the plugin on your WordPress blog. Once installed, you’ll need to create a giveaway contest. This can be done by designing an attractive entry form and ensuring contestants are following the rules by checking their email address and social media account for contest updates. Lastly, make sure to delete fake or multiple entries to keep the giveaway fair. Choose a giveaway plugin that best suits your website’s design and giveaway requirements.
