Supported links with Replug
If you are getting an error while shortening a link with your call-to-action "iFrame is not allowed for your mentioned URL, please try adding a URL that allows the iFrame." The website that you are trying to shorten does not allow the iframe option and in that case, the link will not be shortened. Nearly 1-3% of the most popular websites do not allow the iframe embed option.
Solution:
For the websites which do not allow the iframe embed option, you can create a Campaign with the URL Shortener or Retargeting Pixel. That way, your links will be shortened regardless of the website allows the iframe embed.
In the near future, we will be adding an option for the Fallback Campaign, using that you can select the Campaign which is of type Shortener or Retargeting Pixel only, hence, not having Call to Action within that.
