If your site already outputs schema, you may see multiple JSON-LD script blocks in <code>wp_head</code>. That can mean overlapping entities, harder-to-review markup, and a higher risk of inconsistencies—with no single place to see how Organization, site, and content link together.
ANDPLUS-SchemaBridge outputs one JSON-LD block containing a single coherent <code>@graph</code>, so core types (Organization, WebSite, WebPage, Article, Product, and related items) can stay linked in one graph. It is designed to reduce duplication and make it easier to run this plugin alongside other SEO tools by tuning which types you output in settings.
Core features (no payment required): JSON-LD generation and Schema Monitor work out of the box. No API key is needed for those features.
<ul>
<li>Unified schema graph: Output supported schema types in one JSON-LD block (<code>@graph</code>)</li>
<li>Organization & brand: Configure organization source, name, URL, logo, and sameAs links</li>
<li>Flexible content mapping: Map archives, taxonomies, and post types to appropriate schema types</li>
<li>Schema Monitor: Run manual checks on URLs you register in wp-admin (this package includes one monitor URL). An optional add-on adds higher URL limits, scheduled checks, and reporting.</li>
</ul>
Optional AI interpretation is available when you provide your own OpenAI API key (BYOK). Nothing is sent to OpenAI until you enable and use that feature.

<h4>Support</h4>
Support is limited. We may not be able to respond to individual requests.
<h3>External services</h3>
This plugin may contact external services only when you enable the related features. There is no background tracking of visitors for advertising.
<h4>OpenAI (optional, BYOK)</h4>
Used when you save an OpenAI API key and enable AI interpretation for schema monitoring. Requests go to the OpenAI API (<code>api.openai.com</code>) to send the monitoring/check context and prompts you trigger (e.g. interpretation of schema check results). Nothing is sent until you run a feature that calls the API. You supply your own API key; billing and data processing are governed by OpenAI.

<h4>Schema monitor: fetched URLs</h4>
When you run a schema check or (with the Pro add-on) scheduled monitoring, the plugin requests the URLs you configured in the monitor (and related resources such as the canonical page) over HTTP/HTTPS from your server. No third-party analytics service receives this data; only the targets you entered are contacted.

JSON-LD piles up from themes, blocks, and SEO plugins. One @graph in wp_head links Organization and content—less duplicate markup.

This plugin allows network admin to send organizational messages to blog admins within blog administration.

<li>Every blog admin sees an notification until they mark all messages as read.</li>
<li>Network admin has control over these notifications – can view who has not read which message yet and can delete notifications manually</li>
<li>Message contains title (with or without URL), current date and the content (which can contain HTML)</li>
<li>Notifications are shown to admins of blogs active in time of it’s creation. (probably will be adjustable in the future)</li>
