Dynamic Schema and Meta Tags Not Updating Correctly Due to Server-Side Caching - Support

Hello Rank Math Support Team,

I’m experiencing a complex issue with **schema markup and meta tags not rendering correctly when pages are served from cache** on my website codice fiscal calcolo**, which dynamically generates Italian tax codes (codice fiscale) based on user input.

Here’s what’s happening:

* My site uses full-page caching (via LiteSpeed Cache) to optimize performance.
* Rank Math normally generates the correct meta tags and JSON-LD schema for initial uncached requests.
* However, once a page is cached and served statically, the **dynamic schema data** (for example, generated name, birth date, and codice fiscale results) does not update — it keeps showing the cached user’s data for all subsequent visitors.
* This leads to **structured data mismatches** and incorrect meta information (title, description, and schema fields) being shown to users and crawlers.
* I’ve tried enabling object cache bypass for logged-out users and purging dynamic URLs, but Rank Math’s schema still appears to be tied to the first cached instance of the page.

Could you please advise how Rank Math can handle **dynamic schema and meta rendering** in server-cached environments where pages depend on user input?
Is there a way to isolate Rank Math’s output from static cache or force real-time regeneration of schema and meta tags using a hook (e.g. rank_math/json_ld or rank_math/head)?

This issue is particularly critical for calculator-type sites like mine, where metadata must reflect user-specific dynamic values for accuracy and SEO compliance.

Thank you for your time and for continuously improving Rank Math — your plugin is invaluable for technical SEO work.

Hello,

We apologize for the issue you are facing with schema markup and meta tags not updating correctly due to server-side caching. This can indeed be a complex situation, especially for sites that rely on dynamic user input like yours.

When using full-page caching, it’s common for dynamic content, such as schema data generated based on user input, to be cached along with the rest of the page. Here are a few suggestions to help you manage this issue:
1. Dynamic Caching Configuration: Ensure that your caching plugin (LiteSpeed Cache) is configured to bypass caching for specific pages or user roles. You might want to set rules that prevent caching on pages where dynamic content is generated.
2. Use of AJAX: Consider using AJAX to fetch and display dynamic content without relying on full-page caching. This way, the initial page load can be cached, but the dynamic elements can be loaded separately, ensuring they are always up-to-date.
3. Rank Math Hooks: You can use hooks like rank_math/json_ld to modify the JSON-LD output dynamically. This allows you to inject real-time data into the schema markup based on user input. Here’s a basic example:
```
add_filter('rank_math/json_ld', function($data) {
   // Modify $data based on user input
   return $data;
});
```
  Similarly, you can use rank_math/head to adjust meta tags dynamically.
4. Cache Purging: Make sure to implement cache purging strategies whenever a user submits new data that should affect the schema or meta tags. This could involve purging specific URLs or using cache tags if supported by your caching solution.
5. Testing and Validation: After implementing changes, use tools like Google’s Rich Results Testing Tool to validate that your schema is being generated correctly and reflects the expected dynamic values.
If these suggestions do not resolve the issue, please reply to this ticket with any additional details or specific configurations you have in place, and a human agent from our support team will assist you further.
