Your question was:
Does your plugin support iframes?
I was answering that appropriately. So why you ask then if you already know the answer?
You claim to have read the documentation and yet you did ask how to embed a video with URL. Why? You post the freaking URL or it own line like WordPress like it is described in the documentation.
A typical iframe embed like this IS NOT responsive:
Read what I said!
But if you put a <iframe … inside your post this plugin will do nothing with it. There is a [iframe] shortcode for that …
You:
Please post the code that is supposed to work with a YouTube video in an iframe.
I never spoke of any code that “is supposed to work” I said it may
work.
So you indeed fail to read. You refuse to give me information, refuse to do what I ask and demand some magic code that does not exist. Also after I said that I doubt that it only works for iframes you demand Iframe code.
Why you ask me how to do URL embeds and after I gave you the answer you refuse to try it and demand some magic code? Seriously you show zero effort and I am not willing to go any more baby steps with you.
Like I said the magic code you are looking for is the YouTube URL itelf pasted on its own line. This plugin will do its magic and transform it into a responsive iframe. And since a Youtube URL is in your post content this way the SEO plugin will most likely detect it. I think this came up one time before and it worked for somebody!
But thank you for letting me know that there is indeed no iframe example on my site, I may add this later. So this is how you create a basic Iframe with this plugin with any URL. [iframe id="https://..."]
. Still this is not intended for providers like YouTube that are supported directly. Most features will not work this way.
If you have no time to figure this out, do yourself a favor and drop your SEO plugins and activities. SEO is totally overrated.
Good luck.
