Go to the Twitter Button Generator and choose the type of button you want to create. In this example, it is “Share a link” button,
If you’re using “Share a link” button, copy the website address and paste it to the URL gap. Set other settings eg. name a hashtag, person who recommends the link (it has to be the name of Twitter account). For other buttons, you will have to add similar settings,
Copy the code of your button. Launch the landing page editor and drop the element “Custom” in it. Open it and paste the code of your button. Publish your landing page and see how the button displays and works. You can always go back to the editor and move the button around to some other place on a landing page.
