Google rewards Topical Authority. The Architecture tab allows you to visually construct a Hub & Spoke (Pillar and Cluster) content model, explicitly linking your broad overview pages to your deeply targeted articles.
A Pillar Page is a massive, comprehensive guide covering a broad topic (e.g., "The Ultimate Guide to SEO"). It acts as the "Hub" in your architecture.
Open the SPP Drawer on your broad guide and check the Pillar Page toggle at the top of the Architecture tab. This tells SPP to establish this URL as a foundational hub.
Once Pillar Mode is active, a live AJAX search bar will appear. Search your site for your highly specific, related articles (the "Spokes" or "Clusters").
Click the search results to attach them to the Pillar. SPP will instantly generate a bi-directional Knowledge Graph relationship, writing hasPart schema onto the Pillar, and isPartOf schema onto the Clusters.
Free users can attach up to 3 Cluster Pages to a single Pillar to test the architecture. To build massive, authoritative hubs with 4 or more clusters, you must hold an active Pro or Agency license with EAP Command Center clearance.
Schema relationships are powerful, but search engines also need to see physical HTML links connecting your content on the page itself.
To guarantee you don't create "Orphan Pages", SPP automatically generates an Interlinking Helper box beneath your attached clusters. This box contains a perfectly formatted, clean HTML unordered list of all the articles you just linked. Simply click it to copy, and paste it directly into your WordPress editor (using a Custom HTML block).
You manage your architecture exclusively from the Pillar Page. If you navigate to one of the smaller, supporting "Cluster" articles and open the SPP Drawer, the system will automatically detect the parent-child relationship.
You will see an orange "Cluster Page Detected" notice. This confirms that the current article is actively supporting a primary Pillar, and provides a direct hyperlink back to the parent Hub so you can manage the network.
