Hello,
Thank you for getting in touch with us.
1. Are the tags indexable? You can check from WordPress Dashboard > Rank Math > Titles & Meta > Tags
2. Is the sitemap for tags enabled? You can check that from WordPress Dashboard > Rank Math > Sitemap Settings > Tags.
Please note that we do not recommend making the tag archives indexable. Please only do it if you know what you are doing. Else, your best bet is to keep tags set to noindex and don’t create their sitemaps.
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
