WPXERO

WPXero Iframe adds a dedicated Gutenberg block for external embeds that do not ship a first-party Core block. Use it for videos, maps, audio players, dashboards, booking tools, donation widgets, LMS players, and other iframe-friendly services.
Why this helps SEO and discoverability
<ul>
<li>Editor & directory search — The block title, description, and keyword list match how people look for “iframe block”, “youtube embed”, “maps embed”, “Gutenberg embed”, and similar queries.</li>
<li>On-page context — An optional caption is output as a real <code><figcaption></code> under the embed so your page still has indexable text explaining what visitors are seeing.</li>
<li>Accessible names — Encourages a descriptive <code>title</code> attribute on the iframe for assistive technology and clearer browser behavior.</li>
<li>Crawler-friendly fallback — A <code><noscript></code> block includes a plain link to the sanitized HTTPS embed URL when scripts are off, so bots can still discover the destination.</li>
<li>Performance — Lazy-load mode only loads the small front-end helper script when that option is enabled.</li>
</ul>
Pair it with your SEO plugin (Yoast, Rank Math, SEOPress, AIOSEO, The SEO Framework, etc.) for meta tags, schema, sitemaps, and analytics.

Features Include:
<ul>
<li>The ability to add one or more videos directly in to a page, post or any of your own custom post types using the video URL (not the embed code) or ID and a short code. Currently YouTube and Vimeo are supported, using the [responsive_youtube] and [responsive_vimeo] shortcodes, respectively.</li>
<li>Fully responsive so the video’s viewport will fill the width of the containing area and scale depending on screen size. No need to set a width and height, just set the width of the div your content sits in.</li>
<li>YouTube videos have a shortcode attribute that lets you turn “related videos” on or off. “Related Videos” are the links that tile across the viewport when a video has completed playing.</li>
<li>YouTube videos also support light and dark themes, autoplaying, showinfo, and modest branding (which removes most YouTube brand imagery).</li>
<li>Vimeo videos can have the video portrait, title, and byline shut off.</li>
<li>A comprehensive settings screen which explains all the options and shows you the syntax of the shortcodes.</li>
</ul>
Example Usage:
For a YouTube video, you can specify either full URL to the video or just the unique video ID, or the YouTube sharing or embed URLs, like this:
<pre><code>[responsive_youtube http://www.youtube.com/watch?v=NbCr0UyoFJA ]
[responsive_youtube NbCr0UyoFJA]
[responsive_youtube https://youtu.be//NbCr0UyoFJA ]
[responsive_youtube https://www.youtube.com/embed/NbCr0UyoFJA ]
</code></pre>
And if you want to specify whether or not you’d like the “related videos” to display, you can use the “rel” or “norel” parameters in the shortcode syntax, like this:
<pre><code>[responsive_youtube NbCr0UyoFJA norel]
[responsive_youtube NbCr0UyoFJA rel]
</code></pre>
The rel and norel tags will override whatever you have set in the plugin settings screen for that specific video only.
Similarly, for a Vimeo video, you can use the full video player URL or just the video ID, like this:
<pre><code>[responsive_vimeo https://vimeo.com/29506088 ]
[responsive_vimeo 29506088]
</code></pre>
There is a more complete treatment of the shortcode syntax in the settings screen of the plugin itself.
