Adds custom field to the post & pages editor for custom JSON-ld schema markup also known as structured data. The plugin also validates if the JSON is formated correctly. <a href="http://coderisk.com/wp/plugin/websitescanner-custom-schema/RIPS-8iSfZmxGFd" rel="nofollow ugc"></a>
Add your own JSON-ld on every page, post and custom post without the <code><script></code> to show your own custom Schema markup.
Works well with the following plugins:
<ul>
<li><a href="https://wordpress.org/plugins/remove-schema/" title="Remove Schema WordPress plugin" rel="ugc">Remove Schema</a></li>
</ul>
Usecases:
With the combination of the WordPress plugin it’s easy to overwrite the schema on a specific page. 
If a plugin like Yoast SEO or other plugin or theme that generates schema you can disable the schema and add your own custom schema to the page.

<h3>What’s new in the Cirv ecosystem</h3>
We are building the next plugin in the Cirv suite — Cirv Sight.
Yoast tells you you’re invisible to Google. Cirv Sight tells you you’re invisible to ChatGPT — and lets you charge AI bots to crawl you.
Cirv Sight ships an llms.txt for your WordPress site, then watches what ChatGPT, Claude, Perplexity, and Google AI Overviews actually do with it. Four numbers per page: citations, AI-bot crawls, share of voice, and a Cloudflare 402 pay-per-crawl estimate. If you already use Cirv Box for Google rich results, Cirv Sight is the same idea pointed at AI search. Free on WordPress.org when it ships, Pro for publishers and agencies.
