Video embedding is only available for Premium Listings.
Embedding a video into your listing is very simple. Just paste the iframe code from your video host (YouTube, Vimeo, etc.) into your listing’s Description box.
In your Edit Listing screen, make sure that you are in Text view (not Visual):
To get the embed code at YouTube:
Go to the video page. Below the video, click on Share, then Embed, then copy the iframe code that appears.
To get the embed code at Vimeo:
Go to the video page. Hover your mouse over the top right corner of the video. Click on the Share button, then copy the iframe code that appears.
Paste the embed code into your Description box.
Once you have pasted the code into your Description box, you can switch back to the Visual tab, if you like, to finish formatting your listing.
Be sure to click Save at the bottom of the page to save your changes.
Refresh your listing page to see your video!
