Best Code To Embed?

Hi,

What is usually the best code to embed on a website? IFrame? Embed? Diret Link? 

Which is the best code to use to have less issues on our website?

The best code to use is usually the iFrame code.  Using the iFrame code will insulate the form from the rest of the page and prevent any sort of conflicts between the form and the page.  The iFrame code is also more agreeable on mobile.
