How do I add additional maps, my own, to the index?

@renegat74 You can add an external sitemap to your sitemap using the guide here: https://yoast.com/help/add-external-sitemap-to-index/

We understand you may have sitemaps for other parts of your site that you want to add to our sitemap index. For this purpose, we introduced the wpseo_sitemap_index filter. You will find an example of how to use the filter here: https://gist.github.com/amboutwe/8cfb7a3d8f05e580867341d4ff84141d

Thank you for your response. Could you please specify where I should add the appropriate filters?

@renegat74

It should be added to the functions.php file of your theme

Ok. Thank you.

I added code but it doesn’t work. The pages in the list are not displayed.

Hey @renegat74,

Thank you for your reply.

Sorry to hear that. Have you had a look at the few steps under “Troubleshooting” in the help article linked before? If that doesn’t help, I’m afraid to say that giving support on customizing our plugin or adding custom code is beyond the scope of our support team.
