Quality online quiz builders will allow you to generate an embed code that you can use on your on website or blog. Stay away from quiz builders that only allow you to run quizzes on their site and ask you to link to the quiz. All they are after is your valuable traffic.
If your site is built using WordPress, check first if your quiz builder has a WordPress Plugin. This is usually the easiest way to get your quiz onto your site. Check out the screenshot below from Riddle.com’s WordPress Plugin.
The Riddle Plugin allows you to build quizzes and other interactive content types directly inside the WordPress Admin Backend and then use a shortcode to place the quiz wherever you like on your site.
If you cannot install new plugins on your WordPress installation for security reasons or if you are not running on WordPress, most online quiz builders will give you an embed code that you can use.
Paste your embed code there and you should be good to go.
However, as there are so many different website builders out there, it is hard to generate universal code, that works everywhere. That is why the folks at Riddle.com offer 3 different types of embed code, each a bit lighter with less features, but therefore more compatible with problematic settings.
