To embed a poll, just go to the Polls menu and click on the share-embed button, below the poll you want to embed.
Then, you’ll be able to see three codes: one to show the poll in your blog, another one for Twitter and a third one for Facebook.
Copy the first code. You can use this code and display it either on a post or in your blog’s sidebar.
The first case is a simple as it gets. Just copy the shortcode into the post you’re writing.
To show it in your sidebar it takes a few more steps:
Go to Appearance > Widgets. Drag the polls widget into your sidebar/widgetized footer and enter the code for your poll (e.g. [polldaddy poll=3922742] ).
Enter a title for it (if you want), hit the Save button and all that’s left to do is invite your readers to vote!
