The Preview & Test tab is the final validation gate. It allows you to inspect the compiled JSON-LD code and simulate your search engine appearance in real-time, ensuring your semantic data is error-free before it ever touches Google.
Under the JSON-LD Output section, you can view the raw code being generated by the SPP Engine. This view represents the merger of three distinct data layers:
Pay close attention to the @id strings. SPP uses these to create "nested" relationships, proving to search engines that your author works for your organization and your article is part of your website.
Beneath the code view, you will find the Google Preview. This is a pixel-perfect simulation of how your page will appear on a standard Google Desktop search results page.
Inspect your machine-readable code before going live. Learn how to use the SPP Preview tab to validate compiled JSON-LD and simulate Google search snippets.
The Preview tab updates every time you switch to it. If you change your Meta Description in the SEO tab and then click back to Preview, the SERP simulation will update instantly to reflect your changes.
Once you have validated your architecture, schema, and SERP identity, click the SAVE ENTITY button in the HUD. Unlike the standard WordPress "Update" button, this performs a surgical AJAX save that specifically updates your semantic data without refreshing the entire page.
