BBH Custom Schema – Add Custom JSON-LD to Your Website

Description

BBH Custom Schema gives you full control over your website’s structured data — without the limitations of traditional SEO plugins.

Most SEO plugins automatically generate schema, but they often restrict customization and can create duplicate or conflicting markup. This makes it difficult to control how search engines interpret your content.

BBH Custom Schema solves this by letting you manually add and manage JSON-LD schema on any post or page. You decide exactly what structured data is output — no restrictions, no overrides, no hidden logic.

Perfect for developers, SEO professionals, and advanced users who need precise, flexible control over their schema implementation.

Note: This plugin does not generate schema automatically. You must provide valid JSON-LD format.

What is schema markup?

Schema markup is a special type of structured data that helps search engines understand the content of your website more clearly. Instead of only reading plain text, search engines like Google can identify specific information such as articles, products, reviews, FAQs, events, and more.

When schema markup is added correctly, search engines may display enhanced search results called rich results. These can include extra details like star ratings, FAQ dropdowns, product prices, or article information. Rich results can make your page more noticeable in search results and may increase the chance that users click on your website.

This plugin allows you to add custom JSON-LD schema markup to any post or page so search engines can better interpret your content.

Why I use This Plugin?

This plugin lets you:
* Add custom schema manually
* Fix duplicate schema conflicts
* Helps manage custom schema alongside existing structured data
* Improve search engine understanding
You stay in control of your SEO structure.

Do I need coding knowledge to use this plugin?

Basic knowledge of schema markup can be helpful, but it is not required. The plugin simply provides a place where you can add your schema in JSON-LD format, which is the format recommended by Google.

If you already have schema generated from tools such as Google’s Structured Data Markup Helper or other schema generators, you can copy the JSON-LD code and paste it into the schema box provided by the plugin.

Advanced users and developers may prefer this approach because it gives full control over the schema structure without being limited by preset schema templates.

Does this plugin slow down my website?

No. The plugin is designed to be lightweight and does not add unnecessary scripts, styles, or database queries to your website.

It simply inserts the JSON-LD schema markup into the page output when the page loads. Since JSON-LD is just structured data placed inside a tag, it has no visual impact and minimal performance overhead.

Because of this simple approach, the plugin should not affect your page speed or website performance.

Is it compatible with Rank Math, Yoast SEO, or other SEO plugins?

Yes. The plugin is designed to work alongside popular SEO plugins such as Rank Math, Yoast SEO, and other SEO tools.

In many cases, SEO plugins automatically generate schema markup based on your content. However, sometimes users need to add custom schema that those plugins do not support.

This plugin allows you to insert your own JSON-LD schema and, when necessary, manages custom schema alongside existing structured data. This gives developers and SEO professionals more flexibility when implementing structured data strategies.

Can I add schema to any post or page?

Yes. The plugin allows you to add custom JSON-LD schema to individual posts or pages directly from the WordPress editor. This makes it easy to apply structured data only where it is needed instead of affecting the entire website.

How can I check if my schema is working?

After adding schema to your page, you can verify it using tools such as Google Rich Results Test or other structured data testing tools. These tools will show whether your schema markup is detected and if there are any errors or warnings.

Testing your schema helps ensure that search engines can properly read and interpret the structured data you added.

How do I view the custom schema markup?

Schema markup is for search engines and not displayed to visitors. To see it:
– Press Ctrl + U (View Page Source) on your post or page
– Press Ctrl + F and search for “schema” or “ld+json” to find the script

How can I generate custom schema markup?

This plugin allows you to generate and manage custom schema markup without external tools. You can define structured data in JSON-LD format, assign it to specific content, and control how search engines interpret your pages. Take your require format from below example and modify as your needs.

Also you can use free online tools like:
– https://technicalseo.com/tools/schema-markup-generator/
– or, AI (like ChatGPT, Gemini).

How do I validate my schema markup?

Use these tools to test your schema:
– Inside Post editor you will see a Validate Schema button, simple just click on the button, and check the validity.
– or use Google Rich Results Test
– or, Schema.org Validator

Is BBH Custom Schema responsive?

Yes, the plugin is fully responsive and works on desktop, tablet, and mobile devices.

Can you provide schema markup examples?

Yes. Example schemas are available inside official schema.org documentation.

How to Use These Schema?

  1. Copy any schema example above
  2. Paste it into the plugin schema editor
  3. Customize it for your content
  4. Assign it to posts or pages
  5. Publish and let search engines read it

Can I use Multiple Schemas?

Yes. You can paste multiple JSON-LD schemas one after another (without <script> tags).

Click the Combine Schemas button to merge them into a single valid JSON-LD structure. This resolves syntax errors caused by multiple separate JSON objects.

The tool combines your schemas without modifying the original data.

After that, click Schema Validity Check to verify. You should see: “Valid JSON”.
