How to automatically populate the Subtitle field | CyberSEO Pro | CyberSEO support forum

CyberSEO Pro does not have a predefined custom field for subtitles. The subtitle field in your WordPress post editor is generated by your WordPress theme or a third-party plugin.

While CyberSEO Pro can generate a subtitle using Claude or any other LLM, and save it to that field, the plugin needs to know the exact meta key of the custom field. Since the field belongs to your active theme, its impossible to tell what the meta key is.

There are two ways you can find the correct custom field name yourself. One way is to use your browser's web inspector tool on the post editor page and look at the ID of the subtitle input field, as it often matches the meta key name. Alternatively, you can create a test post, fill in the subtitle field, publish the post, and check the standard WordPress custom fields block to see which key was saved to the database.

Once you find the exact name of the custom field, you can put any value there using the following code:

This code saves the value to the custom field with the name you specified. Just open a post created by the plugin and check its custom fields (you can access them in the top-right corner, where it says Screen options). If the subtitle doesn't appear, it means the actual name of the custom field for it isn't "jnews_post_subtitle", but something else. Contact the developer of your WordPress theme for clarification.
